156 SHA256, SHA384, SHA512 and Whirlpool digest functions have been
157 deprecated.
158 * All of the low-level AES, Blowfish, Camellia, CAST, DES, IDEA, RC2,
159 RC4, RC5 and SEED cipher functions have been deprecated.
160 * All of the low-level DH, DSA, ECDH, ECDSA and RSA public key functions
161 have been deprecated.
162 * SSL 3, TLS 1.0, TLS 1.1, and DTLS 1.0 only work at security level 0,
