(PowerBuilder) Calculate MD5 Hash of File (or SHA1, SHA256, and other hash algorithms)

Demonstrates how to calculate a hash for a file's contents.

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

// Use "Chilkat_9_5_0.Crypt2" for versions of Chilkat < 10.0.0

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

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

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