=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() mainly adds ciphers and digests used directly by SSL/TLS.
+In some cases this is not sufficient and errors about unknown algorithms
+will occur: for example when an attempt is made to use a certificate using
+SHA256. This can be resolved by also calling OpenSSL_add_all_algorithms().
