 145     PKCS12 KDF, SCRYPT, SSH KDF, SSKDF, TLS1 PRF, X9.42 KDF and X9.63 KDF.
 146   * All of the low-level MD2, MD4, MD5, MDC2, RIPEMD160, SHA1, SHA224,
 147     SHA256, SHA384, SHA512 and Whirlpool digest functions have been
 148     deprecated.

 150     RC4, RC5 and SEED cipher functions have been deprecated.
