=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.

=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.
