What will be an ideal response?
The algorithms supported are as follows:
* MD2: The MD2 message digest algorithm defined in RFC 1319.
* MD5: The MD5 message digest algorithm defined in RFC 1321.
* SHA-1: The Secure Hash Algorithm defined in Secure Hash Standard, NIST FIPS 180-1.
* SHA-256, SHA-384, and SHA-512: Hash algorithms from the draft Federal Information Processing Standard 180-2, Secure Hash Standard (SHS). SHA-256 is a 256-bit hash function providing 128 bits of security against collision attacks. SHA-512 is a 512-bit hash function providing 256 bits of security.
