(Visual FoxPro) 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.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Crypt2')
loCrypt = CreateObject('Chilkat.Crypt2')

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

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

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