44 +=head1 DESCRIPTION
45 +
46 +The B<passwd> command computes the hash of a password typed at
47 +run-time or the hash of each password in a list. The password list is
48 +taken from the named file for option B<-in file>, from stdin for
49 +option B<-stdin>, or from the command line, or from the terminal otherwise.
50 +The Unix standard algorithm B<crypt> and the MD5-based BSD password
51 +algorithm B<1> and its Apache variant B<apr1> are available.

512 -=head1 DESCRIPTION
513 -
514 -When a call to the OpenSSL library fails, this is usually signalled
515 -by the return value, and an error code is stored in an error queue
516 -associated with the current thread. The B<err> library provides
517 -functions to obtain these error codes and textual error messages.
518 -
519 -The L<ERR_get_error(3)|ERR_get_error(3)> manpage describes how to
520 -access error codes.
521 -
522 -Error codes contain information about where the error occurred, and
523 -what went wrong. L<ERR_GET_LIB(3)|ERR_GET_LIB(3)> describes how to
524 -extract this information. A method to obtain human-readable error
525 -messages is described in L<ERR_error_string(3)|ERR_error_string(3)>.
526 -
527 -L<ERR_clear_error(3)|ERR_clear_error(3)> can be used to clear the
528 -error queue.
529 -
530 -Note that L<ERR_remove_state(3)|ERR_remove_state(3)> should be used to
531 -avoid memory leaks when threads are terminated.
532 -
533 -=head1 ADDING NEW ERROR CODES TO OPENSSL
534 -
535 -See L<ERR_put_error(3)> if you want to record error codes in the
536 -OpenSSL error system from within your application.
537 -
538 -The remainder of this section is of interest only if you want to add
539 -new error codes to OpenSSL or add error codes from external libraries.
540 -
541 -=head2 Reporting errors
542 -
543 -Each sub-library has a specific macro XXXerr() that is used to report
544 -errors. Its first argument is a function code B<XXX_F_...>, the second
545 -argument is a reason code B<XXX_R_...>. Function codes are derived
546 -from the function names; reason codes consist of textual error
547 -descriptions. For example, the function ssl23_read() reports a
548 -"handshake failure" as follows:
549 -
550 - SSLerr(SSL_F_SSL23_READ, SSL_R_SSL_HANDSHAKE_FAILURE);
551 -
552 -Function and reason codes should consist of upper case characters,
553 -numbers and underscores only. The error file generation script translates
554 -function codes into function names by looking in the header files
555 -for an appropriate function name, if none is found it just uses
556 -the capitalized form such as "SSL23_READ" in the above example.
557 -
558 -The trailing section of a reason code (after the "_R_") is translated
559 -into lower case and underscores changed to spaces.
560 -
561 -When you are using new function or reason codes, run B<make errors>.
562 -The necessary B<#define>s will then automatically be added to the
563 -sub-library's header file.
564 -
565 -Although a library will normally report errors using its own specific
566 -XXXerr macro, another library's macro can be used. This is normally
567 -only done when a library wants to include ASN1 code which must use
568 -the ASN1err() macro.
569 -
570 -=head2 Adding new libraries
571 -
572 -When adding a new sub-library to OpenSSL, assign it a library number
573 -B<ERR_LIB_XXX>, define a macro XXXerr() (both in B<err.h>), add its
574 -name to B<ERR_str_libraries[]> (in B<crypto/err/err.c>), and add
575 -C<ERR_load_XXX_strings()> to the ERR_load_crypto_strings() function
576 -(in B<crypto/err/err_all.c>). Finally, add an entry
577 -
578 - L XXX xxx.h xxx_err.c
579 -
580 -to B<crypto/err/openssl.ec>, and add B<xxx_err.c> to the Makefile.
581 -Running B<make errors> will then generate a file B<xxx_err.c>, and
582 -add all error codes used in the library to B<xxx.h>.
583 -
584 -Additionally the library include file must have a certain form.
585 -Typically it will initially look like this:
586 -
587 - #ifndef HEADER_XXX_H
588 - #define HEADER_XXX_H
589 -
590 - #ifdef __cplusplus
591 - extern "C" {
592 - #endif
593 -
594 - /* Include files */
595 -
596 - #include <openssl/bio.h>
597 - #include <openssl/x509.h>
598 -
599 - /* Macros, structures and function prototypes */
600 -
601 -
602 - /* BEGIN ERROR CODES */
603 -
604 -The B<BEGIN ERROR CODES> sequence is used by the error code
605 -generation script as the point to place new error codes, any text
606 -after this point will be overwritten when B<make errors> is run.
607 -The closing #endif etc will be automatically added by the script.
608 -
609 -The generated C error code file B<xxx_err.c> will load the header
610 -files B<stdio.h>, B<openssl/err.h> and B<openssl/xxx.h> so the
611 -header file must load any additional header files containing any
612 -definitions it uses.
613 -
614 -=head1 USING ERROR CODES IN EXTERNAL LIBRARIES
615 -
616 -It is also possible to use OpenSSL's error code scheme in external
617 -libraries. The library needs to load its own codes and call the OpenSSL
618 -error code insertion script B<mkerr.pl> explicitly to add codes to
619 -the header file and generate the C error code file. This will normally
620 -be done if the external library needs to generate new ASN1 structures
621 -but it can also be used to add more general purpose error code handling.
622 -
623 -TBA more details
624 -
625 -=head1 INTERNALS
626 -
627 -The error queues are stored in a hash table with one B<ERR_STATE>
628 -entry for each pid. ERR_get_state() returns the current thread's
629 -B<ERR_STATE>. An B<ERR_STATE> can hold up to B<ERR_NUM_ERRORS> error
630 -codes. When more error codes are added, the old ones are overwritten,
631 -on the assumption that the most recent errors are most important.
632 -
633 -Error strings are also stored in hash table. The hash tables can
634 -be obtained by calling ERR_get_err_state_table(void) and
635 -ERR_get_string_table(void) respectively.

805 +associated with the current thread. The B<err> library provides
806 +functions to obtain these error codes and textual error messages.
807 +
808 +The L<ERR_get_error(3)|ERR_get_error(3)> manpage describes how to
809 +access error codes.
810 +
811 +Error codes contain information about where the error occurred, and
812 +what went wrong. L<ERR_GET_LIB(3)|ERR_GET_LIB(3)> describes how to
813 +extract this information. A method to obtain human-readable error
814 +messages is described in L<ERR_error_string(3)|ERR_error_string(3)>.
815 +
816 +L<ERR_clear_error(3)|ERR_clear_error(3)> can be used to clear the
817 +error queue.
818 +
819 +Note that L<ERR_remove_state(3)|ERR_remove_state(3)> should be used to
820 +avoid memory leaks when threads are terminated.
821 +
822 +=head1 ADDING NEW ERROR CODES TO OPENSSL
823 +
824 +See L<ERR_put_error(3)> if you want to record error codes in the
825 +OpenSSL error system from within your application.
826 +
827 +The remainder of this section is of interest only if you want to add
828 +new error codes to OpenSSL or add error codes from external libraries.
829 +
830 +=head2 Reporting errors
831 +
832 +Each sub-library has a specific macro XXXerr() that is used to report
833 +errors. Its first argument is a function code B<XXX_F_...>, the second
834 +argument is a reason code B<XXX_R_...>. Function codes are derived
835 +from the function names; reason codes consist of textual error
836 +descriptions. For example, the function ssl23_read() reports a
837 +"handshake failure" as follows:
838 +
839 + SSLerr(SSL_F_SSL23_READ, SSL_R_SSL_HANDSHAKE_FAILURE);
840 +
841 +Function and reason codes should consist of upper case characters,
842 +numbers and underscores only. The error file generation script translates
843 +function codes into function names by looking in the header files
844 +for an appropriate function name, if none is found it just uses
845 +the capitalized form such as "SSL23_READ" in the above example.
846 +
847 +The trailing section of a reason code (after the "_R_") is translated
848 +into lower case and underscores changed to spaces.
849 +
850 +When you are using new function or reason codes, run B<make errors>.
851 +The necessary B<#define>s will then automatically be added to the
852 +sub-library's header file.
853 +
854 +Although a library will normally report errors using its own specific
855 +XXXerr macro, another library's macro can be used. This is normally
856 +only done when a library wants to include ASN1 code which must use
857 +the ASN1err() macro.
858 +
859 +=head2 Adding new libraries
860 +
861 +When adding a new sub-library to OpenSSL, assign it a library number
862 +B<ERR_LIB_XXX>, define a macro XXXerr() (both in B<err.h>), add its
863 +name to B<ERR_str_libraries[]> (in B<crypto/err/err.c>), and add
864 +C<ERR_load_XXX_strings()> to the ERR_load_crypto_strings() function
865 +(in B<crypto/err/err_all.c>). Finally, add an entry
866 +
867 + L XXX xxx.h xxx_err.c
868 +
869 +to B<crypto/err/openssl.ec>, and add B<xxx_err.c> to the Makefile.
870 +Running B<make errors> will then generate a file B<xxx_err.c>, and
871 +add all error codes used in the library to B<xxx.h>.
872 +
873 +Additionally the library include file must have a certain form.
874 +Typically it will initially look like this:
875 +
876 + #ifndef HEADER_XXX_H
877 + #define HEADER_XXX_H
878 +
879 + #ifdef __cplusplus
880 + extern "C" {
881 + #endif
882 +
883 + /* Include files */
884 +
885 + #include <openssl/bio.h>
886 + #include <openssl/x509.h>
887 +
888 + /* Macros, structures and function prototypes */
889 +
890 +
891 + /* BEGIN ERROR CODES */
892 +
893 +The B<BEGIN ERROR CODES> sequence is used by the error code
894 +generation script as the point to place new error codes, any text
895 +after this point will be overwritten when B<make errors> is run.
896 +The closing #endif etc will be automatically added by the script.
897 +
898 +The generated C error code file B<xxx_err.c> will load the header
899 +files B<stdio.h>, B<openssl/err.h> and B<openssl/xxx.h> so the
900 +header file must load any additional header files containing any
901 +definitions it uses.
902 +
903 +=head1 USING ERROR CODES IN EXTERNAL LIBRARIES
904 +
905 +It is also possible to use OpenSSL's error code scheme in external
906 +libraries. The library needs to load its own codes and call the OpenSSL
907 +error code insertion script B<mkerr.pl> explicitly to add codes to
908 +the header file and generate the C error code file. This will normally
909 +be done if the external library needs to generate new ASN1 structures
910 +but it can also be used to add more general purpose error code handling.
911 +
912 +TBA more details
913 +
914 +=head1 INTERNALS
915 +
916 +The error queues are stored in a hash table with one B<ERR_STATE>
917 +entry for each pid. ERR_get_state() returns the current thread's
918 +B<ERR_STATE>. An B<ERR_STATE> can hold up to B<ERR_NUM_ERRORS> error
919 +codes. When more error codes are added, the old ones are overwritten,
920 +on the assumption that the most recent errors are most important.
921 +
922 +Error strings are also stored in hash table. The hash tables can
923 +be obtained by calling ERR_get_err_state_table(void) and
924 +ERR_get_string_table(void) respectively.

980 +=head1 DESCRIPTION
981 +
982 +Since the introduction of the ENGINE API, the recommended way of controlling
983 +default implementations is by using the ENGINE API functions. The default
984 +B<RAND_METHOD>, as set by RAND_set_rand_method() and returned by
985 +RAND_get_rand_method(), is only used if no ENGINE has been set as the default
986 +"rand" implementation. Hence, these two functions are no longer the recommened
987 +way to control defaults.
988 +
989 +If an alternative B<RAND_METHOD> implementation is being used (either set
990 +directly or as provided by an ENGINE module), then it is entirely responsible
991 +for the generation and management of a cryptographically secure PRNG stream. The
992 +mechanisms described below relate solely to the software PRNG implementation
993 +built in to OpenSSL and used by default.
994 +
995 +These functions implement a cryptographically secure pseudo-random
996 +number generator (PRNG). It is used by other library functions for
997 +example to generate random keys, and applications can use it when they
998 +need randomness.
999 +
1000 +A cryptographic PRNG must be seeded with unpredictable data such as
1001 +mouse movements or keys pressed at random by the user. This is
1002 +described in L<RAND_add(3)|RAND_add(3)>. Its state can be saved in a seed file
1003 +(see L<RAND_load_file(3)|RAND_load_file(3)>) to avoid having to go through the
1004 +seeding process whenever the application is started.
1005 +
1006 +L<RAND_bytes(3)|RAND_bytes(3)> describes how to obtain random data from the
1007 +PRNG.
1008 +
1009 +=head1 INTERNALS
1010 +
1011 +The RAND_SSLeay() method implements a PRNG based on a cryptographic
1012 +hash function.
1013 +
1014 +The following description of its design is based on the SSLeay
1015 +documentation:
1016 +
1017 +First up I will state the things I believe I need for a good RNG.
1018 +
1019 +=over 4
1020 +
1021 +=item 1
1022 +
1023 +A good hashing algorithm to mix things up and to convert the RNG 'state'
1024 +to random numbers.
1025 +
1026 +=item 2
1027 +
1028 +An initial source of random 'state'.
1029 +
1030 +=item 3
1031 +
1032 +The state should be very large. If the RNG is being used to generate
1033 +4096 bit RSA keys, 2 2048 bit random strings are required (at a minimum).
1034 +If your RNG state only has 128 bits, you are obviously limiting the
1035 +search space to 128 bits, not 2048. I'm probably getting a little
1036 +carried away on this last point but it does indicate that it may not be
1037 +a bad idea to keep quite a lot of RNG state. It should be easier to
1038 +break a cipher than guess the RNG seed data.
1039 +
1040 +=item 4
1041 +
1042 +Any RNG seed data should influence all subsequent random numbers
1043 +generated. This implies that any random seed data entered will have
1044 +an influence on all subsequent random numbers generated.
1045 +
1046 +=item 5
1047 +
1048 +When using data to seed the RNG state, the data used should not be
1049 +extractable from the RNG state. I believe this should be a
1050 +requirement because one possible source of 'secret' semi random
1051 +data would be a private key or a password. This data must
1052 +not be disclosed by either subsequent random numbers or a
1053 +'core' dump left by a program crash.
1054 +
1055 +=item 6
1056 +
1057 +Given the same initial 'state', 2 systems should deviate in their RNG state
1058 +(and hence the random numbers generated) over time if at all possible.
1059 +
1060 +=item 7
1061 +
1062 +Given the random number output stream, it should not be possible to determine
1063 +the RNG state or the next random number.
1064 +
1065 +=back
1066 +
1067 +The algorithm is as follows.
1068 +
1069 +There is global state made up of a 1023 byte buffer (the 'state'), a
1070 +working hash value ('md'), and a counter ('count').
1071 +
1072 +Whenever seed data is added, it is inserted into the 'state' as
1073 +follows.
1074 +
1075 +The input is chopped up into units of 20 bytes (or less for
1076 +the last block). Each of these blocks is run through the hash
1077 +function as follows: The data passed to the hash function
1078 +is the current 'md', the same number of bytes from the 'state'
1079 +(the location determined by in incremented looping index) as
1080 +the current 'block', the new key data 'block', and 'count'
1081 +(which is incremented after each use).
1082 +The result of this is kept in 'md' and also xored into the
1083 +'state' at the same locations that were used as input into the
1084 +hash function. I
1085 +believe this system addresses points 1 (hash function; currently
1086 +SHA-1), 3 (the 'state'), 4 (via the 'md'), 5 (by the use of a hash
1087 +function and xor).
1088 +
1089 +When bytes are extracted from the RNG, the following process is used.
1090 +For each group of 10 bytes (or less), we do the following:
1091 +
1092 +Input into the hash function the local 'md' (which is initialized from
1093 +the global 'md' before any bytes are generated), the bytes that are to
1094 +be overwritten by the random bytes, and bytes from the 'state'
1095 +(incrementing looping index). From this digest output (which is kept
1096 +in 'md'), the top (up to) 10 bytes are returned to the caller and the
1097 +bottom 10 bytes are xored into the 'state'.
1098 +
1099 +Finally, after we have finished 'num' random bytes for the caller,
1100 +'count' (which is incremented) and the local and global 'md' are fed
1101 +into the hash function and the results are kept in the global 'md'.
1102 +
1103 +I believe the above addressed points 1 (use of SHA-1), 6 (by hashing
1104 +into the 'state' the 'old' data from the caller that is about to be
1105 +overwritten) and 7 (by not using the 10 bytes given to the caller to
1106 +update the 'state', but they are used to update 'md').
1107 +
1108 +So of the points raised, only 2 is not addressed (but see
1109 +L<RAND_add(3)|RAND_add(3)>).

1186 +=head1 DESCRIPTION
1187 +
1188 +OpenSSL can safely be used in multi-threaded applications provided
1189 +that at least two callback functions are set, locking_function and
1190 +threadid_func.
1191 +
1192 +locking_function(int mode, int n, const char *file, int line) is
1193 +needed to perform locking on shared data structures.
1194 +(Note that OpenSSL uses a number of global data structures that
1195 +will be implicitly shared whenever multiple threads use OpenSSL.)
1196 +Multi-threaded applications will crash at random if it is not set.
1197 +
1198 +locking_function() must be able to handle up to CRYPTO_num_locks()
1199 +different mutex locks. It sets the B<n>-th lock if B<mode> &
1200 +B<CRYPTO_LOCK>, and releases it otherwise.
1201 +
1202 +B<file> and B<line> are the file number of the function setting the
1203 +lock. They can be useful for debugging.
1204 +
1205 +threadid_func(CRYPTO_THREADID *id) is needed to record the currently-executing
1206 +thread's identifier into B<id>. The implementation of this callback should not
1207 +fill in B<id> directly, but should use CRYPTO_THREADID_set_numeric() if thread
1208 +IDs are numeric, or CRYPTO_THREADID_set_pointer() if they are pointer-based.
1209 +If the application does not register such a callback using
1210 +CRYPTO_THREADID_set_callback(), then a default implementation is used - on
1211 +Windows and BeOS this uses the system's default thread identifying APIs, and on
1212 +all other platforms it uses the address of B<errno>. The latter is satisfactory
1213 +for thread-safety if and only if the platform has a thread-local error number
1214 +facility.
1215 +
1216 +Once threadid_func() is registered, or if the built-in default implementation is
1217 +to be used;
1218 +
1219 +=over 4
1220 +
1221 +=item *
1222 +CRYPTO_THREADID_current() records the currently-executing thread ID into the
1223 +given B<id> object.
1224 +
1225 +=item *
1226 +CRYPTO_THREADID_cmp() compares two thread IDs (returning zero for equality, ie.
1227 +the same semantics as memcmp()).
1228 +
1229 +=item *
1230 +CRYPTO_THREADID_cpy() duplicates a thread ID value,
1231 +
1232 +=item *
1233 +CRYPTO_THREADID_hash() returns a numeric value usable as a hash-table key. This
1234 +is usually the exact numeric or pointer-based thread ID used internally, however
1235 +this also handles the unusual case where pointers are larger than 'long'
1236 +variables and the platform's thread IDs are pointer-based - in this case, mixing
1237 +is done to attempt to produce a unique numeric value even though it is not as
1238 +wide as the platform's true thread IDs.
1239 +
1240 +=back
1241 +
1242 +Additionally, OpenSSL supports dynamic locks, and sometimes, some parts
1243 +of OpenSSL need it for better performance. To enable this, the following
1244 +is required:
1245 +
1246 +=over 4
1247 +
1248 +=item *
1249 +Three additional callback function, dyn_create_function, dyn_lock_function
1250 +and dyn_destroy_function.
1251 +
1252 +=item *
1253 +A structure defined with the data that each lock needs to handle.
1254 +
1255 +=back
1256 +
1257 +struct CRYPTO_dynlock_value has to be defined to contain whatever structure
1258 +is needed to handle locks.
1259 +
1260 +dyn_create_function(const char *file, int line) is needed to create a
1261 +lock. Multi-threaded applications might crash at random if it is not set.
1262 +
1263 +dyn_lock_function(int mode, CRYPTO_dynlock *l, const char *file, int line)
1264 +is needed to perform locking off dynamic lock numbered n. Multi-threaded
1265 +applications might crash at random if it is not set.
1266 +
1267 +dyn_destroy_function(CRYPTO_dynlock *l, const char *file, int line) is
1268 +needed to destroy the lock l. Multi-threaded applications might crash at

1298 +
1299 +You can find out if OpenSSL was configured with thread support:
1300 +
1301 + #define OPENSSL_THREAD_DEFINES
1302 + #include <openssl/opensslconf.h>
1303 + #if defined(OPENSSL_THREADS)
1304 + // thread support enabled
1305 + #else
1306 + // no thread support
1307 + #endif
1308 +
1309 +Also, dynamic locks are currently not used internally by OpenSSL, but
1310 +may do so in the future.

1316 +
1317 +=head1 HISTORY
1318 +
1319 +CRYPTO_set_locking_callback() is
1320 +available in all versions of SSLeay and OpenSSL.
1321 +CRYPTO_num_locks() was added in OpenSSL 0.9.4.
1322 +All functions dealing with dynamic locks were added in OpenSSL 0.9.5b-dev.
1323 +B<CRYPTO_THREADID> and associated functions were introduced in OpenSSL 1.0.0
1324 +to replace (actually, deprecate) the previous CRYPTO_set_id_callback(),
1325 +CRYPTO_get_id_callback(), and CRYPTO_thread_id() functions which assumed
1326 +thread IDs to always be represented by 'unsigned long'.

1426 -=head1 DESCRIPTION
1427 -
1428 -Since the introduction of the ENGINE API, the recommended way of controlling
1429 -default implementations is by using the ENGINE API functions. The default
1430 -B<RAND_METHOD>, as set by RAND_set_rand_method() and returned by
1431 -RAND_get_rand_method(), is only used if no ENGINE has been set as the default
1432 -"rand" implementation. Hence, these two functions are no longer the recommened
1433 -way to control defaults.
1434 -
1435 -If an alternative B<RAND_METHOD> implementation is being used (either set
1436 -directly or as provided by an ENGINE module), then it is entirely responsible
1437 -for the generation and management of a cryptographically secure PRNG stream. The
1438 -mechanisms described below relate solely to the software PRNG implementation
1439 -built in to OpenSSL and used by default.
1440 -
1441 -These functions implement a cryptographically secure pseudo-random
1442 -number generator (PRNG). It is used by other library functions for
1443 -example to generate random keys, and applications can use it when they
1444 -need randomness.
1445 -
1446 -A cryptographic PRNG must be seeded with unpredictable data such as
1447 -mouse movements or keys pressed at random by the user. This is
1448 -described in L<RAND_add(3)|RAND_add(3)>. Its state can be saved in a seed file
1449 -(see L<RAND_load_file(3)|RAND_load_file(3)>) to avoid having to go through the
1450 -seeding process whenever the application is started.
1451 -
1452 -L<RAND_bytes(3)|RAND_bytes(3)> describes how to obtain random data from the
1453 -PRNG.
1454 -
1455 -=head1 INTERNALS
1456 -
1457 -The RAND_SSLeay() method implements a PRNG based on a cryptographic
1458 -hash function.
1459 -
1460 -The following description of its design is based on the SSLeay
1461 -documentation:
1462 -
1463 -First up I will state the things I believe I need for a good RNG.
1464 -
1465 -=over 4
1466 -
1467 -=item 1
1468 -
1469 -A good hashing algorithm to mix things up and to convert the RNG 'state'
1470 -to random numbers.
1471 -
1472 -=item 2
1473 -
1474 -An initial source of random 'state'.
1475 -
1476 -=item 3
1477 -
1478 -The state should be very large. If the RNG is being used to generate
1479 -4096 bit RSA keys, 2 2048 bit random strings are required (at a minimum).
1480 -If your RNG state only has 128 bits, you are obviously limiting the
1481 -search space to 128 bits, not 2048. I'm probably getting a little
1482 -carried away on this last point but it does indicate that it may not be
1483 -a bad idea to keep quite a lot of RNG state. It should be easier to
1484 -break a cipher than guess the RNG seed data.
1485 -
1486 -=item 4
1487 -
1488 -Any RNG seed data should influence all subsequent random numbers
1489 -generated. This implies that any random seed data entered will have
1490 -an influence on all subsequent random numbers generated.
1491 -
1492 -=item 5
1493 -
1494 -When using data to seed the RNG state, the data used should not be
1495 -extractable from the RNG state. I believe this should be a
1496 -requirement because one possible source of 'secret' semi random
1497 -data would be a private key or a password. This data must
1498 -not be disclosed by either subsequent random numbers or a
1499 -'core' dump left by a program crash.
1500 -
1501 -=item 6
1502 -
1503 -Given the same initial 'state', 2 systems should deviate in their RNG state
1504 -(and hence the random numbers generated) over time if at all possible.
1505 -
1506 -=item 7
1507 -
1508 -Given the random number output stream, it should not be possible to determine
1509 -the RNG state or the next random number.
1510 -
1511 -=back
1512 -
1513 -The algorithm is as follows.
1514 -
1515 -There is global state made up of a 1023 byte buffer (the 'state'), a
1516 -working hash value ('md'), and a counter ('count').
1517 -
1518 -Whenever seed data is added, it is inserted into the 'state' as
1519 -follows.
1520 -
1521 -The input is chopped up into units of 20 bytes (or less for
1522 -the last block). Each of these blocks is run through the hash
1523 -function as follows: The data passed to the hash function
1524 -is the current 'md', the same number of bytes from the 'state'
1525 -(the location determined by in incremented looping index) as
1526 -the current 'block', the new key data 'block', and 'count'
1527 -(which is incremented after each use).
1528 -The result of this is kept in 'md' and also xored into the
1529 -'state' at the same locations that were used as input into the
1530 -hash function. I
1531 -believe this system addresses points 1 (hash function; currently
1532 -SHA-1), 3 (the 'state'), 4 (via the 'md'), 5 (by the use of a hash
1533 -function and xor).
1534 -
1535 -When bytes are extracted from the RNG, the following process is used.
1536 -For each group of 10 bytes (or less), we do the following:
1537 -
1538 -Input into the hash function the local 'md' (which is initialized from
1539 -the global 'md' before any bytes are generated), the bytes that are to
1540 -be overwritten by the random bytes, and bytes from the 'state'
1541 -(incrementing looping index). From this digest output (which is kept
1542 -in 'md'), the top (up to) 10 bytes are returned to the caller and the
1543 -bottom 10 bytes are xored into the 'state'.
1544 -
1545 -Finally, after we have finished 'num' random bytes for the caller,
1546 -'count' (which is incremented) and the local and global 'md' are fed
1547 -into the hash function and the results are kept in the global 'md'.
1548 -
1549 -I believe the above addressed points 1 (use of SHA-1), 6 (by hashing
1550 -into the 'state' the 'old' data from the caller that is about to be
1551 -overwritten) and 7 (by not using the 10 bytes given to the caller to
1552 -update the 'state', but they are used to update 'md').
1553 -
1554 -So of the points raised, only 2 is not addressed (but see
1555 -L<RAND_add(3)|RAND_add(3)>).

1698 -=head1 DESCRIPTION
1699 -
1700 -OpenSSL can safely be used in multi-threaded applications provided
1701 -that at least two callback functions are set, locking_function and
1702 -threadid_func.
1703 -
1704 -locking_function(int mode, int n, const char *file, int line) is
1705 -needed to perform locking on shared data structures.
1706 -(Note that OpenSSL uses a number of global data structures that
1707 -will be implicitly shared whenever multiple threads use OpenSSL.)
1708 -Multi-threaded applications will crash at random if it is not set.
1709 -
1710 -locking_function() must be able to handle up to CRYPTO_num_locks()
1711 -different mutex locks. It sets the B<n>-th lock if B<mode> &
1712 -B<CRYPTO_LOCK>, and releases it otherwise.
1713 -
1714 -B<file> and B<line> are the file number of the function setting the
1715 -lock. They can be useful for debugging.
1716 -
1717 -threadid_func(CRYPTO_THREADID *id) is needed to record the currently-executing
1718 -thread's identifier into B<id>. The implementation of this callback should not
1719 -fill in B<id> directly, but should use CRYPTO_THREADID_set_numeric() if thread
1720 -IDs are numeric, or CRYPTO_THREADID_set_pointer() if they are pointer-based.
1721 -If the application does not register such a callback using
1722 -CRYPTO_THREADID_set_callback(), then a default implementation is used - on
1723 -Windows and BeOS this uses the system's default thread identifying APIs, and on
1724 -all other platforms it uses the address of B<errno>. The latter is satisfactory
1725 -for thread-safety if and only if the platform has a thread-local error number
1726 -facility.
1727 -
1728 -Once threadid_func() is registered, or if the built-in default implementation is
1729 -to be used;
1730 -
1731 -=over 4
1732 -
1733 -=item *
1734 -CRYPTO_THREADID_current() records the currently-executing thread ID into the
1735 -given B<id> object.
1736 -
1737 -=item *
1738 -CRYPTO_THREADID_cmp() compares two thread IDs (returning zero for equality, ie.
1739 -the same semantics as memcmp()).
1740 -
1741 -=item *
1742 -CRYPTO_THREADID_cpy() duplicates a thread ID value,
1743 -
1744 -=item *
1745 -CRYPTO_THREADID_hash() returns a numeric value usable as a hash-table key. This
1746 -is usually the exact numeric or pointer-based thread ID used internally, however
1747 -this also handles the unusual case where pointers are larger than 'long'
1748 -variables and the platform's thread IDs are pointer-based - in this case, mixing
1749 -is done to attempt to produce a unique numeric value even though it is not as
1750 -wide as the platform's true thread IDs.
1751 -
1752 -=back
1753 -
1754 -Additionally, OpenSSL supports dynamic locks, and sometimes, some parts
1755 -of OpenSSL need it for better performance. To enable this, the following
1756 -is required:
1757 -
1758 -=over 4
1759 -
1760 -=item *
1761 -Three additional callback function, dyn_create_function, dyn_lock_function
1762 -and dyn_destroy_function.
1763 -
1764 -=item *
1765 -A structure defined with the data that each lock needs to handle.
1766 -
1767 -=back
1768 -
1769 -struct CRYPTO_dynlock_value has to be defined to contain whatever structure
1770 -is needed to handle locks.
1771 -
1772 -dyn_create_function(const char *file, int line) is needed to create a
1773 -lock. Multi-threaded applications might crash at random if it is not set.
1774 -
1775 -dyn_lock_function(int mode, CRYPTO_dynlock *l, const char *file, int line)
1776 -is needed to perform locking off dynamic lock numbered n. Multi-threaded
1777 -applications might crash at random if it is not set.
1778 -
1779 -dyn_destroy_function(CRYPTO_dynlock *l, const char *file, int line) is
1780 -needed to destroy the lock l. Multi-threaded applications might crash at
1781 -random if it is not set.
1782 -
1783 -CRYPTO_get_new_dynlockid() is used to create locks. It will call
1784 -dyn_create_function for the actual creation.
1785 -
1786 -CRYPTO_destroy_dynlockid() is used to destroy locks. It will call
1787 -dyn_destroy_function for the actual destruction.
1788 -
1789 -CRYPTO_lock() is used to lock and unlock the locks. mode is a bitfield
1790 -describing what should be done with the lock. n is the number of the
1791 -lock as returned from CRYPTO_get_new_dynlockid(). mode can be combined
1792 -from the following values. These values are pairwise exclusive, with
1793 -undefined behaviour if misused (for example, CRYPTO_READ and CRYPTO_WRITE
1794 -should not be used together):
1795 -
1796 - CRYPTO_LOCK 0x01
1797 - CRYPTO_UNLOCK 0x02
1798 - CRYPTO_READ 0x04
1799 - CRYPTO_WRITE 0x08
1800 -
1801 -=head1 RETURN VALUES
1802 -
1803 -CRYPTO_num_locks() returns the required number of locks.
1804 -
1805 -CRYPTO_get_new_dynlockid() returns the index to the newly created lock.
1806 -
1807 -The other functions return no values.
1808 -
1809 -=head1 NOTES
1810 -
1811 -You can find out if OpenSSL was configured with thread support:
1812 -
1813 - #define OPENSSL_THREAD_DEFINES
1814 - #include <openssl/opensslconf.h>
1815 - #if defined(OPENSSL_THREADS)
1816 - // thread support enabled
1817 - #else
1818 - // no thread support
1819 - #endif
1820 -
1821 -Also, dynamic locks are currently not used internally by OpenSSL, but
1822 -may do so in the future.
1823 -
1824 -=head1 EXAMPLES
1825 -
1826 -B<crypto/threads/mttest.c> shows examples of the callback functions on
1827 -Solaris, Irix and Win32.
1828 -
1829 -=head1 HISTORY
1830 -
1831 -CRYPTO_set_locking_callback() is
1832 -available in all versions of SSLeay and OpenSSL.
1833 -CRYPTO_num_locks() was added in OpenSSL 0.9.4.
1834 -All functions dealing with dynamic locks were added in OpenSSL 0.9.5b-dev.
1835 -B<CRYPTO_THREADID> and associated functions were introduced in OpenSSL 1.0.0
1836 -to replace (actually, deprecate) the previous CRYPTO_set_id_callback(),
1837 -CRYPTO_get_id_callback(), and CRYPTO_thread_id() functions which assumed
1838 -thread IDs to always be represented by 'unsigned long'.
