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

set crypt [new_CkCrypt2]

# The output will be Hex, so set the EncodingMode:
CkCrypt2_put_EncodingMode $crypt "hex"

# Set the hash algorithm:
# Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
