 =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().
