Compute Glacier SHA256 Linear Hash of a File

See more Amazon Glacier Examples

Computes the Amazon Glacier SHA256 linear hash for a file. VBScript

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.

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.

outFile.WriteLine("SHA256 linear hash = " & linearHashHex)
