SSL_library_init() registers the available SSL/TLS ciphers and digests.

       OpenSSL_add_ssl_algorithms() is a synonym for SSL_library_init() and is implemented as a macro.

       The SSL_library_init() and OpenSSL_add_ssl_algorithms() functions were deprecated in OpenSSL 1.1.0 by
       OPENSSL_init_ssl().

SSL_library_init() must be called before any other action takes place.  SSL_library_init() is not
       reentrant.

SSL_library_init() always returns "1", so it is safe to discard the return value.

        int SSL_library_init(void);

        int OpenSSL_add_ssl_algorithms(void);

SSL_library_init() adds ciphers and digests used directly and indirectly by SSL/TLS.
