Available hash algorithms
=========================
`GCRY_MD_NONE'
This is not a real algorithm but used by some functions as an error
return value. This constant is guaranteed to have the value `0'.
`GCRY_MD_SHA1'
This is the SHA-1 algorithm which yields a message digest of 20
bytes.
`GCRY_MD_RMD160'
This is the 160 bit version of the RIPE message digest
(RIPE-MD-160). Like SHA-1 it also yields a digest of 20 bytes.
`GCRY_MD_MD5'
This is the well known MD5 algorithm, which yields a message
digest of 16 bytes.
`GCRY_MD_MD4'
This is the MD4 algorithm, which yields a message digest of 16
bytes.
`GCRY_MD_MD2'
This is an reserved identifier for MD-2; there is no
implementation yet.
`GCRY_MD_TIGER'
This is the TIGER/192 algorithm which yields a message digest of
24 bytes.
`GCRY_MD_HAVAL'
This is an reserved for the HAVAL algorithm with 5 passes and 160
bit. It yields a message digest of 20 bytes. Note that there is no
implementation yet available.
`GCRY_MD_SHA256'
This is the SHA-256 algorithm which yields a message digest of 32
bytes. See FIPS 180-2 for the specification.
`GCRY_MD_SHA384'
This is reserved for SHA-2 with 384 bits. It yields a message
digest of 48 bytes. Note that there is no implementation yet
available.
`GCRY_MD_SHA512'
This is reserved for SHA-2 with 512 bits. It yields a message
digest of 64 bytes. Note that there is no implementation yet
available.
`GCRY_MD_CRC32'
This is the ISO 3309 and ITU-T V.42 cyclic redundancy check. It
yields an output of 4 bytes.
`GCRY_MD_CRC32_RFC1510'
This is the above cyclic redundancy check function, as modified by
RFC 1510. It yields an output of 4 bytes.
`GCRY_MD_CRC24_RFC2440'
This is the OpenPGP cyclic redundancy check function. It yields an
output of 3 bytes.
