Computes the Amazon Glacier SHA256 linear hash for a file.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

JavaScript

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

var crypt = new CkCrypt2();

// The "linear hash" is simply the SHA256 hash of the file bytes.
crypt.HashAlgorithm = "sha256";

// Return the hash in lowercase hexidecimal format.
crypt.EncodingMode = "hexlower";

var linearHashHex = crypt.HashFileENC("qa_data/jpg/penguins.jpg");
console.log("SHA256 linear hash = " + linearHashHex);
