(VBScript) Compute Glacier SHA256 Linear Hash of a File
Computes the Amazon Glacier SHA256 linear hash for a file.
Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)
' This example requires 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")
set crypt = CreateObject("Chilkat.Crypt2")
' 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"
linearHashHex = crypt.HashFileENC("qa_data/jpg/penguins.jpg")
outFile.WriteLine("SHA256 linear hash = " & linearHashHex)
outFile.Close
