Computes the Amazon Glacier SHA256 linear hash for a file. Visual FoxPro

LOCAL loCrypt
LOCAL lcLinearHashHex

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

loCrypt = CreateObject('Chilkat.Crypt2')

* The "linear hash" is simply the SHA256 hash of the file bytes.
loCrypt.HashAlgorithm = "sha256"

* Return the hash in lowercase hexidecimal format.
loCrypt.EncodingMode = "hexlower"

lcLinearHashHex = loCrypt.HashFileENC("qa_data/jpg/penguins.jpg")
? "SHA256 linear hash = " + lcLinearHashHex
