Hash File: SHA-1, HAVAL, MD2, MD5, SHA-256, SHA-384, SHA-512

Computing the hash for a file of any size.

#  Any string argument automatically begins the 30-day trial.

#  Any type of file may be hashed.
#  There is  no size limitation because the file is consumed
#  in streaming mode internally.

#  Other possible EncodingMode settings are:
#  "quoted-printable", "base64", and "url"

hash = crypt.hashFileENC(filename)
print "SHA1:"
print hash

#  Hash using MD2
crypt.put_HashAlgorithm("md2")
hash = crypt.hashFileENC(filename)
print "MD2:"
print hash

#  Hash using MD5
crypt.put_HashAlgorithm("md5")
hash = crypt.hashFileENC(filename)
print "MD5:"
print hash

#  Hash using SHA-256
crypt.put_HashAlgorithm("sha256")
hash = crypt.hashFileENC(filename)
print "SHA256:"
print hash

#  Hash using SHA-384
crypt.put_HashAlgorithm("sha384")
hash = crypt.hashFileENC(filename)
print "SHA384:"
print hash

#  Hash using SHA-512
crypt.put_HashAlgorithm("sha512")
hash = crypt.hashFileENC(filename)
print "SHA512:"
print hash

#  Hash using HAVAL
#  There are two additional properties relevant to HAVAL:
#  HavalRounds, and KeyLength.
#  HavalRounds can have values of 3, 4, or 5.
#  KeyLength can have values of 128, 160, 192, 224, or 256
crypt.put_HashAlgorithm("haval")
crypt.put_HavalRounds(5)
crypt.put_KeyLength(256)
hash = crypt.hashFileENC(filename)
print "Haval:"
print hash
