134 deprecated.
135 * All of the low-level AES, Blowfish, Camellia, CAST, DES, IDEA, RC2,
136 RC4, RC5 and SEED cipher functions have been deprecated.
137 * All of the low-level DH, DSA, ECDH, ECDSA and RSA public key functions
138 have been deprecated.
139 * SSL 3, TLS 1.0, TLS 1.1, and DTLS 1.0 only work at security level 0,
140 except when RSA key exchange without SHA1 is used.
