=head1 DESCRIPTION



The B<EVP_PKEY_TLS1_PRF> algorithm implements the PRF key derivation function for

TLS. It has no associated private key and only implements key derivation

using EVP_PKEY_derive().

using L<EVP_PKEY_derive(3)>.



EVP_PKEY_set_tls1_prf_md() sets the message digest associated with the

TLS PRF. EVP_md5_sha1() is treated as a special case which uses the PRF
