#  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 using MD2

#  Hash using MD5
crypt.put_HashAlgorithm("md5")

#  Hash using SHA-256

#  Hash using SHA-384

#  Hash using SHA-512

#  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
