# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

$crypt = New-Object Chilkat.Crypt2

# Set the name of the hash algorithm.
# Other choices include "sha1", "sha256", "sha384", "sha512", "md2", "md5", and "haval". 
$crypt.HashAlgorithm = "md5"

# EncodingMode specifies the encoding of the hash output.
# It may be "hex", "url", "base64", or "quoted-printable".
$crypt.EncodingMode = "hex"

# Files of any type may be hashed -- it doesn't matter
# if the file is binary or text...
