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

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

LOCAL cHashStr

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

oCrypt := CreateObject("Chilkat.Crypt2")

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

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

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