=head1 DESCRIPTION
-SSL_library_init() registers the available ciphers and digests.
+SSL_library_init() registers the available SSL/TLS ciphers and digests.
OpenSSL_add_ssl_algorithms() and SSLeay_add_ssl_algorithms() are synonyms
for SSL_library_init().
=head1 WARNING
-SSL_library_init() only registers ciphers. Another important initialization
-is the seeding of the PRNG (Pseudo Random Number Generator), which has to
-be performed separately.
+SSL_library_init() adds ciphers and digests used directly and indirectly by
+SSL/TLS.
=head1 EXAMPLES
A typical TLS/SSL application will start with the library initialization,
-will provide readable error messages and will seed the PRNG.
+and provide readable error messages.
SSL_load_error_strings(); /* readable error messages */
SSL_library_init(); /* initialize library */
- actions_to_seed_PRNG();
=head1 RETURN VALUES
SSL_library_init() always returns "1", so it is safe to discard the return
value.
+=head1 NOTES
+
+OpenSSL 0.9.8o and 1.0.0a and later added SHA2 algorithms to SSL_library_init().
+Applications which need to use SHA2 in earlier versions of OpenSSL should call
+OpenSSL_add_all_algorithms() as well.
