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

-=head1 DESCRIPTION
-
-When a call to the OpenSSL library fails, this is usually signalled
-by the return value, and an error code is stored in an error queue
-associated with the current thread. The B<err> library provides
-functions to obtain these error codes and textual error messages.
-
-The L<ERR_get_error(3)|ERR_get_error(3)> manpage describes how to
-access error codes.
-
-Error codes contain information about where the error occurred, and
-what went wrong. L<ERR_GET_LIB(3)|ERR_GET_LIB(3)> describes how to
-extract this information. A method to obtain human-readable error
-messages is described in L<ERR_error_string(3)|ERR_error_string(3)>.
-
-L<ERR_clear_error(3)|ERR_clear_error(3)> can be used to clear the
-error queue.
-
-Note that L<ERR_remove_state(3)|ERR_remove_state(3)> should be used to
-avoid memory leaks when threads are terminated.
-
-=head1 ADDING NEW ERROR CODES TO OPENSSL
-
-See L<ERR_put_error(3)> if you want to record error codes in the
-OpenSSL error system from within your application.
-
-The remainder of this section is of interest only if you want to add
-new error codes to OpenSSL or add error codes from external libraries.
-
-=head2 Reporting errors
-
-Each sub-library has a specific macro XXXerr() that is used to report
-errors. Its first argument is a function code B<XXX_F_...>, the second
-argument is a reason code B<XXX_R_...>. Function codes are derived
-from the function names; reason codes consist of textual error
-descriptions. For example, the function ssl23_read() reports a
-"handshake failure" as follows:
-
- SSLerr(SSL_F_SSL23_READ, SSL_R_SSL_HANDSHAKE_FAILURE);
-
-Function and reason codes should consist of upper case characters,
-numbers and underscores only. The error file generation script translates
-function codes into function names by looking in the header files
-for an appropriate function name, if none is found it just uses
-the capitalized form such as "SSL23_READ" in the above example.
-
-The trailing section of a reason code (after the "_R_") is translated
-into lower case and underscores changed to spaces.
-
-When you are using new function or reason codes, run B<make errors>.
-The necessary B<#define>s will then automatically be added to the
-sub-library's header file.
-
-Although a library will normally report errors using its own specific
-XXXerr macro, another library's macro can be used. This is normally
-only done when a library wants to include ASN1 code which must use
-the ASN1err() macro.
-
-=head2 Adding new libraries
-
-When adding a new sub-library to OpenSSL, assign it a library number
-B<ERR_LIB_XXX>, define a macro XXXerr() (both in B<err.h>), add its
-name to B<ERR_str_libraries[]> (in B<crypto/err/err.c>), and add
-C<ERR_load_XXX_strings()> to the ERR_load_crypto_strings() function
-(in B<crypto/err/err_all.c>). Finally, add an entry
-
- L XXX xxx.h xxx_err.c
-
-to B<crypto/err/openssl.ec>, and add B<xxx_err.c> to the Makefile.
-Running B<make errors> will then generate a file B<xxx_err.c>, and
-add all error codes used in the library to B<xxx.h>.
-
-Additionally the library include file must have a certain form.
-Typically it will initially look like this:
-
- #ifndef HEADER_XXX_H
- #define HEADER_XXX_H
-
- #ifdef __cplusplus
- extern "C" {
- #endif
-
- /* Include files */
-
- #include <openssl/bio.h>
- #include <openssl/x509.h>
-
- /* Macros, structures and function prototypes */
-
-
- /* BEGIN ERROR CODES */
-
-The B<BEGIN ERROR CODES> sequence is used by the error code
-generation script as the point to place new error codes, any text
-after this point will be overwritten when B<make errors> is run.
-The closing #endif etc will be automatically added by the script.
-
-The generated C error code file B<xxx_err.c> will load the header
-files B<stdio.h>, B<openssl/err.h> and B<openssl/xxx.h> so the
-header file must load any additional header files containing any
-definitions it uses.
-
-=head1 USING ERROR CODES IN EXTERNAL LIBRARIES
-
-It is also possible to use OpenSSL's error code scheme in external
-libraries. The library needs to load its own codes and call the OpenSSL
-error code insertion script B<mkerr.pl> explicitly to add codes to
-the header file and generate the C error code file. This will normally
-be done if the external library needs to generate new ASN1 structures
-but it can also be used to add more general purpose error code handling.
-
-TBA more details
-
-=head1 INTERNALS
-
-The error queues are stored in a hash table with one B<ERR_STATE>
-entry for each pid. ERR_get_state() returns the current thread's
-B<ERR_STATE>. An B<ERR_STATE> can hold up to B<ERR_NUM_ERRORS> error
-codes. When more error codes are added, the old ones are overwritten,
-on the assumption that the most recent errors are most important.
-
-Error strings are also stored in hash table. The hash tables can
-be obtained by calling ERR_get_err_state_table(void) and
-ERR_get_string_table(void) respectively.

+=head1 DESCRIPTION
+
+Since the introduction of the ENGINE API, the recommended way of controlling
+default implementations is by using the ENGINE API functions. The default
+B<RAND_METHOD>, as set by RAND_set_rand_method() and returned by
+RAND_get_rand_method(), is only used if no ENGINE has been set as the default
+"rand" implementation. Hence, these two functions are no longer the recommened
+way to control defaults.
+
+If an alternative B<RAND_METHOD> implementation is being used (either set
+directly or as provided by an ENGINE module), then it is entirely responsible
+for the generation and management of a cryptographically secure PRNG stream. The
+mechanisms described below relate solely to the software PRNG implementation
+built in to OpenSSL and used by default.
+
+These functions implement a cryptographically secure pseudo-random
+number generator (PRNG). It is used by other library functions for
+example to generate random keys, and applications can use it when they
+need randomness.
+
+A cryptographic PRNG must be seeded with unpredictable data such as
+mouse movements or keys pressed at random by the user. This is
+described in L<RAND_add(3)|RAND_add(3)>. Its state can be saved in a seed file
+(see L<RAND_load_file(3)|RAND_load_file(3)>) to avoid having to go through the
+seeding process whenever the application is started.
+
+L<RAND_bytes(3)|RAND_bytes(3)> describes how to obtain random data from the
+PRNG.
+
+=head1 INTERNALS
+
+The RAND_SSLeay() method implements a PRNG based on a cryptographic
+hash function.
+
+The following description of its design is based on the SSLeay
+documentation:
+
+First up I will state the things I believe I need for a good RNG.
+
+=over 4
+
+=item 1
+
+A good hashing algorithm to mix things up and to convert the RNG 'state'
+to random numbers.
+
+=item 2
+
+An initial source of random 'state'.
+
+=item 3
+
+The state should be very large. If the RNG is being used to generate
+4096 bit RSA keys, 2 2048 bit random strings are required (at a minimum).
+If your RNG state only has 128 bits, you are obviously limiting the
+search space to 128 bits, not 2048. I'm probably getting a little
+carried away on this last point but it does indicate that it may not be
+a bad idea to keep quite a lot of RNG state. It should be easier to
+break a cipher than guess the RNG seed data.
+
+=item 4
+
+Any RNG seed data should influence all subsequent random numbers
+generated. This implies that any random seed data entered will have
+an influence on all subsequent random numbers generated.
+
+=item 5
+
+When using data to seed the RNG state, the data used should not be
+extractable from the RNG state. I believe this should be a
+requirement because one possible source of 'secret' semi random
+data would be a private key or a password. This data must
+not be disclosed by either subsequent random numbers or a
+'core' dump left by a program crash.
+
+=item 6
+
+Given the same initial 'state', 2 systems should deviate in their RNG state
+(and hence the random numbers generated) over time if at all possible.
+
+=item 7
+
+Given the random number output stream, it should not be possible to determine
+the RNG state or the next random number.
+
+=back
+
+The algorithm is as follows.
+
+There is global state made up of a 1023 byte buffer (the 'state'), a
+working hash value ('md'), and a counter ('count').
+
+Whenever seed data is added, it is inserted into the 'state' as
+follows.
+
+The input is chopped up into units of 20 bytes (or less for
+the last block). Each of these blocks is run through the hash
+function as follows: The data passed to the hash function
+is the current 'md', the same number of bytes from the 'state'
+(the location determined by in incremented looping index) as
+the current 'block', the new key data 'block', and 'count'
+(which is incremented after each use).
+The result of this is kept in 'md' and also xored into the
+'state' at the same locations that were used as input into the
+hash function. I
+believe this system addresses points 1 (hash function; currently
+SHA-1), 3 (the 'state'), 4 (via the 'md'), 5 (by the use of a hash
+function and xor).
+
+When bytes are extracted from the RNG, the following process is used.
+For each group of 10 bytes (or less), we do the following:
+
+Input into the hash function the local 'md' (which is initialized from
+the global 'md' before any bytes are generated), the bytes that are to
+be overwritten by the random bytes, and bytes from the 'state'
+(incrementing looping index). From this digest output (which is kept
+in 'md'), the top (up to) 10 bytes are returned to the caller and the
+bottom 10 bytes are xored into the 'state'.
+
+Finally, after we have finished 'num' random bytes for the caller,
+'count' (which is incremented) and the local and global 'md' are fed
+into the hash function and the results are kept in the global 'md'.
+
+I believe the above addressed points 1 (use of SHA-1), 6 (by hashing
+into the 'state' the 'old' data from the caller that is about to be
+overwritten) and 7 (by not using the 10 bytes given to the caller to
+update the 'state', but they are used to update 'md').
+
+So of the points raised, only 2 is not addressed (but see
+L<RAND_add(3)|RAND_add(3)>).

+
+=head1 DESCRIPTION
+
+OpenSSL can safely be used in multi-threaded applications provided
+that at least two callback functions are set, locking_function and
+threadid_func.
+
+locking_function(int mode, int n, const char *file, int line) is
+needed to perform locking on shared data structures.
+(Note that OpenSSL uses a number of global data structures that
+will be implicitly shared whenever multiple threads use OpenSSL.)
+Multi-threaded applications will crash at random if it is not set.
+
+locking_function() must be able to handle up to CRYPTO_num_locks()
+different mutex locks. It sets the B<n>-th lock if B<mode> &
+B<CRYPTO_LOCK>, and releases it otherwise.
+
+B<file> and B<line> are the file number of the function setting the
+lock. They can be useful for debugging.
+
+threadid_func(CRYPTO_THREADID *id) is needed to record the currently-executing
+thread's identifier into B<id>. The implementation of this callback should not
+fill in B<id> directly, but should use CRYPTO_THREADID_set_numeric() if thread
+IDs are numeric, or CRYPTO_THREADID_set_pointer() if they are pointer-based.
+If the application does not register such a callback using
+CRYPTO_THREADID_set_callback(), then a default implementation is used - on
+Windows and BeOS this uses the system's default thread identifying APIs, and on
+all other platforms it uses the address of B<errno>. The latter is satisfactory
+for thread-safety if and only if the platform has a thread-local error number
+facility.
+
+Once threadid_func() is registered, or if the built-in default implementation is
+to be used;
+
+=over 4
+
+=item *
+CRYPTO_THREADID_current() records the currently-executing thread ID into the
+given B<id> object.
+
+=item *
+CRYPTO_THREADID_cmp() compares two thread IDs (returning zero for equality, ie.
+the same semantics as memcmp()).
+
+=item *
+CRYPTO_THREADID_cpy() duplicates a thread ID value,
+
+=item *
+CRYPTO_THREADID_hash() returns a numeric value usable as a hash-table key. This
+is usually the exact numeric or pointer-based thread ID used internally, however
+this also handles the unusual case where pointers are larger than 'long'
+variables and the platform's thread IDs are pointer-based - in this case, mixing
+is done to attempt to produce a unique numeric value even though it is not as
+wide as the platform's true thread IDs.
+
+=back
+
+Additionally, OpenSSL supports dynamic locks, and sometimes, some parts
+of OpenSSL need it for better performance. To enable this, the following
+is required:
+
+=over 4
+
+=item *
+Three additional callback function, dyn_create_function, dyn_lock_function
+and dyn_destroy_function.
+
+=item *
+A structure defined with the data that each lock needs to handle.
+
+=back
+
+struct CRYPTO_dynlock_value has to be defined to contain whatever structure
+is needed to handle locks.
+
+dyn_create_function(const char *file, int line) is needed to create a
+lock. Multi-threaded applications might crash at random if it is not set.
+
+dyn_lock_function(int mode, CRYPTO_dynlock *l, const char *file, int line)
+is needed to perform locking off dynamic lock numbered n. Multi-threaded
+applications might crash at random if it is not set.
+
+dyn_destroy_function(CRYPTO_dynlock *l, const char *file, int line) is
+needed to destroy the lock l. Multi-threaded applications might crash at
+random if it is not set.
+
+CRYPTO_get_new_dynlockid() is used to create locks. It will call
+dyn_create_function for the actual creation.
+
+CRYPTO_destroy_dynlockid() is used to destroy locks. It will call
+dyn_destroy_function for the actual destruction.
+
+CRYPTO_lock() is used to lock and unlock the locks. mode is a bitfield
+describing what should be done with the lock. n is the number of the
+lock as returned from CRYPTO_get_new_dynlockid(). mode can be combined
+from the following values. These values are pairwise exclusive, with
+undefined behaviour if misused (for example, CRYPTO_READ and CRYPTO_WRITE
+should not be used together):
+
+ CRYPTO_LOCK 0x01
+ CRYPTO_UNLOCK 0x02
+ CRYPTO_READ 0x04
+ CRYPTO_WRITE 0x08
+
+=head1 RETURN VALUES
+
+CRYPTO_num_locks() returns the required number of locks.
+
+CRYPTO_get_new_dynlockid() returns the index to the newly created lock.
+
+The other functions return no values.
+
+=head1 NOTES
+
+You can find out if OpenSSL was configured with thread support:
+
+ #define OPENSSL_THREAD_DEFINES
+ #include <openssl/opensslconf.h>
+ #if defined(OPENSSL_THREADS)
+ // thread support enabled
+ #else
+ // no thread support
+ #endif
+
+Also, dynamic locks are currently not used internally by OpenSSL, but
+may do so in the future.
+
+=head1 EXAMPLES
+
+B<crypto/threads/mttest.c> shows examples of the callback functions on
+Solaris, Irix and Win32.
+
+=head1 HISTORY
+
+CRYPTO_set_locking_callback() is
+available in all versions of SSLeay and OpenSSL.
+CRYPTO_num_locks() was added in OpenSSL 0.9.4.
+All functions dealing with dynamic locks were added in OpenSSL 0.9.5b-dev.
+B<CRYPTO_THREADID> and associated functions were introduced in OpenSSL 1.0.0
+to replace (actually, deprecate) the previous CRYPTO_set_id_callback(),
+CRYPTO_get_id_callback(), and CRYPTO_thread_id() functions which assumed
+thread IDs to always be represented by 'unsigned long'.

-=head1 DESCRIPTION
-
-Since the introduction of the ENGINE API, the recommended way of controlling
-default implementations is by using the ENGINE API functions. The default
-B<RAND_METHOD>, as set by RAND_set_rand_method() and returned by
-RAND_get_rand_method(), is only used if no ENGINE has been set as the default
-"rand" implementation. Hence, these two functions are no longer the recommened
-way to control defaults.
-
-If an alternative B<RAND_METHOD> implementation is being used (either set
-directly or as provided by an ENGINE module), then it is entirely responsible
-for the generation and management of a cryptographically secure PRNG stream. The
-mechanisms described below relate solely to the software PRNG implementation
-built in to OpenSSL and used by default.
-
-These functions implement a cryptographically secure pseudo-random
-number generator (PRNG). It is used by other library functions for
-example to generate random keys, and applications can use it when they
-need randomness.
-
-A cryptographic PRNG must be seeded with unpredictable data such as
-mouse movements or keys pressed at random by the user. This is
-described in L<RAND_add(3)|RAND_add(3)>. Its state can be saved in a seed file
-(see L<RAND_load_file(3)|RAND_load_file(3)>) to avoid having to go through the
-seeding process whenever the application is started.
-
-L<RAND_bytes(3)|RAND_bytes(3)> describes how to obtain random data from the
-PRNG.
-
-=head1 INTERNALS
-
-The RAND_SSLeay() method implements a PRNG based on a cryptographic
-hash function.
-
-The following description of its design is based on the SSLeay
-documentation:
-
-First up I will state the things I believe I need for a good RNG.
-
-=over 4
-
-=item 1
-
-A good hashing algorithm to mix things up and to convert the RNG 'state'
-to random numbers.
-
-=item 2
-
-An initial source of random 'state'.
-
-=item 3
-
-The state should be very large. If the RNG is being used to generate
-4096 bit RSA keys, 2 2048 bit random strings are required (at a minimum).
-If your RNG state only has 128 bits, you are obviously limiting the
-search space to 128 bits, not 2048. I'm probably getting a little
-carried away on this last point but it does indicate that it may not be
-a bad idea to keep quite a lot of RNG state. It should be easier to
-break a cipher than guess the RNG seed data.
-
-=item 4
-
-Any RNG seed data should influence all subsequent random numbers
-generated. This implies that any random seed data entered will have
-an influence on all subsequent random numbers generated.
-
-=item 5
-
-When using data to seed the RNG state, the data used should not be
-extractable from the RNG state. I believe this should be a
-requirement because one possible source of 'secret' semi random
-data would be a private key or a password. This data must
-not be disclosed by either subsequent random numbers or a
-'core' dump left by a program crash.
-
-=item 6
-
-Given the same initial 'state', 2 systems should deviate in their RNG state
-(and hence the random numbers generated) over time if at all possible.
-
-=item 7
-
-Given the random number output stream, it should not be possible to determine
-the RNG state or the next random number.
-
-=back
-
-The algorithm is as follows.
-
-There is global state made up of a 1023 byte buffer (the 'state'), a
-working hash value ('md'), and a counter ('count').
-
-Whenever seed data is added, it is inserted into the 'state' as
-follows.
-
-The input is chopped up into units of 20 bytes (or less for
-the last block). Each of these blocks is run through the hash
-function as follows: The data passed to the hash function
-is the current 'md', the same number of bytes from the 'state'
-(the location determined by in incremented looping index) as
-the current 'block', the new key data 'block', and 'count'
-(which is incremented after each use).
-The result of this is kept in 'md' and also xored into the
-'state' at the same locations that were used as input into the
-hash function. I
-believe this system addresses points 1 (hash function; currently
-SHA-1), 3 (the 'state'), 4 (via the 'md'), 5 (by the use of a hash
-function and xor).
-
-When bytes are extracted from the RNG, the following process is used.
-For each group of 10 bytes (or less), we do the following:
-
-Input into the hash function the local 'md' (which is initialized from
-the global 'md' before any bytes are generated), the bytes that are to
-be overwritten by the random bytes, and bytes from the 'state'
-(incrementing looping index). From this digest output (which is kept
-in 'md'), the top (up to) 10 bytes are returned to the caller and the
-bottom 10 bytes are xored into the 'state'.
-
-Finally, after we have finished 'num' random bytes for the caller,
-'count' (which is incremented) and the local and global 'md' are fed
-into the hash function and the results are kept in the global 'md'.
-
-I believe the above addressed points 1 (use of SHA-1), 6 (by hashing
-into the 'state' the 'old' data from the caller that is about to be
-overwritten) and 7 (by not using the 10 bytes given to the caller to
-update the 'state', but they are used to update 'md').
-
-So of the points raised, only 2 is not addressed (but see
-L<RAND_add(3)|RAND_add(3)>).

-=head1 DESCRIPTION
-
-OpenSSL can safely be used in multi-threaded applications provided
-that at least two callback functions are set, locking_function and
-threadid_func.
-
-locking_function(int mode, int n, const char *file, int line) is
-needed to perform locking on shared data structures.
-(Note that OpenSSL uses a number of global data structures that
-will be implicitly shared whenever multiple threads use OpenSSL.)
-Multi-threaded applications will crash at random if it is not set.
-
-locking_function() must be able to handle up to CRYPTO_num_locks()
-different mutex locks. It sets the B<n>-th lock if B<mode> &
-B<CRYPTO_LOCK>, and releases it otherwise.
-
-B<file> and B<line> are the file number of the function setting the
-lock. They can be useful for debugging.
-
-threadid_func(CRYPTO_THREADID *id) is needed to record the currently-executing
-thread's identifier into B<id>. The implementation of this callback should not
-fill in B<id> directly, but should use CRYPTO_THREADID_set_numeric() if thread
-IDs are numeric, or CRYPTO_THREADID_set_pointer() if they are pointer-based.
-If the application does not register such a callback using
-CRYPTO_THREADID_set_callback(), then a default implementation is used - on
-Windows and BeOS this uses the system's default thread identifying APIs, and on
-all other platforms it uses the address of B<errno>. The latter is satisfactory
-for thread-safety if and only if the platform has a thread-local error number
-facility.
-
-Once threadid_func() is registered, or if the built-in default implementation is
-to be used;
-
-=over 4
-
-=item *
-CRYPTO_THREADID_current() records the currently-executing thread ID into the
-given B<id> object.
-
-=item *
-CRYPTO_THREADID_cmp() compares two thread IDs (returning zero for equality, ie.
-the same semantics as memcmp()).
-
-=item *
-CRYPTO_THREADID_cpy() duplicates a thread ID value,
-
-=item *
-CRYPTO_THREADID_hash() returns a numeric value usable as a hash-table key. This
-is usually the exact numeric or pointer-based thread ID used internally, however
-this also handles the unusual case where pointers are larger than 'long'
-variables and the platform's thread IDs are pointer-based - in this case, mixing
-is done to attempt to produce a unique numeric value even though it is not as
-wide as the platform's true thread IDs.
-
-=back
-
-Additionally, OpenSSL supports dynamic locks, and sometimes, some parts
-of OpenSSL need it for better performance. To enable this, the following
-is required:
-
-=over 4
-
-=item *
-Three additional callback function, dyn_create_function, dyn_lock_function
-and dyn_destroy_function.
-
-=item *
-A structure defined with the data that each lock needs to handle.
-
-=back
-
-struct CRYPTO_dynlock_value has to be defined to contain whatever structure
-is needed to handle locks.
-
-dyn_create_function(const char *file, int line) is needed to create a
-lock. Multi-threaded applications might crash at random if it is not set.
-
-dyn_lock_function(int mode, CRYPTO_dynlock *l, const char *file, int line)
-is needed to perform locking off dynamic lock numbered n. Multi-threaded
-applications might crash at random if it is not set.
-
-dyn_destroy_function(CRYPTO_dynlock *l, const char *file, int line) is
-needed to destroy the lock l. Multi-threaded applications might crash at
-random if it is not set.
-
-CRYPTO_get_new_dynlockid() is used to create locks. It will call
-dyn_create_function for the actual creation.
-
-CRYPTO_destroy_dynlockid() is used to destroy locks. It will call
-dyn_destroy_function for the actual destruction.
-
-CRYPTO_lock() is used to lock and unlock the locks. mode is a bitfield
-describing what should be done with the lock. n is the number of the
-lock as returned from CRYPTO_get_new_dynlockid(). mode can be combined
-from the following values. These values are pairwise exclusive, with
-undefined behaviour if misused (for example, CRYPTO_READ and CRYPTO_WRITE
-should not be used together):
-
- CRYPTO_LOCK 0x01
- CRYPTO_UNLOCK 0x02
- CRYPTO_READ 0x04
- CRYPTO_WRITE 0x08
-
-=head1 RETURN VALUES
-
-CRYPTO_num_locks() returns the required number of locks.
-
-CRYPTO_get_new_dynlockid() returns the index to the newly created lock.
-
-The other functions return no values.
-
-=head1 NOTES
-
-You can find out if OpenSSL was configured with thread support:
-
- #define OPENSSL_THREAD_DEFINES
- #include <openssl/opensslconf.h>
- #if defined(OPENSSL_THREADS)
- // thread support enabled
- #else
- // no thread support
- #endif
-
-Also, dynamic locks are currently not used internally by OpenSSL, but
-may do so in the future.
-
-=head1 EXAMPLES
-
-B<crypto/threads/mttest.c> shows examples of the callback functions on
-Solaris, Irix and Win32.
-
-=head1 HISTORY
-
-CRYPTO_set_locking_callback() is
-available in all versions of SSLeay and OpenSSL.
-CRYPTO_num_locks() was added in OpenSSL 0.9.4.
-All functions dealing with dynamic locks were added in OpenSSL 0.9.5b-dev.
-B<CRYPTO_THREADID> and associated functions were introduced in OpenSSL 1.0.0
-to replace (actually, deprecate) the previous CRYPTO_set_id_callback(),
-CRYPTO_get_id_callback(), and CRYPTO_thread_id() functions which assumed
-thread IDs to always be represented by 'unsigned long'.
