141    PKCS12 KDF, SCRYPT, SSH KDF, SSKDF, TLS1 PRF, X9.42 KDF and X9.63 KDF.
142  * All of the low-level MD2, MD4, MD5, MDC2, RIPEMD160, SHA1, SHA224,
143    SHA256, SHA384, SHA512 and Whirlpool digest functions have been
144    deprecated.
145  * All of the low-level AES, Blowfish, Camellia, CAST, DES, IDEA, RC2,
146    RC4, RC5 and SEED cipher functions have been deprecated.
147  * All of the low-level DH, DSA, ECDH, ECDSA and RSA public key functions
148    have been deprecated.
149  * SSL 3, TLS 1.0, TLS 1.1, and DTLS 1.0 only work at security level 0,
150    except when RSA key exchange without SHA1 is used.
