Hash the Contents of a File (SHA256 and other hash algorithms)

See more Encryption Examples

Demonstrates how to hash the contents of a file using SHA256, SHA384, SHA512, MD2, MD5, HAVAL, RIPEMD, etc. AutoIt

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

$oCrypt = ObjCreate("Chilkat.Crypt2")

;  Choose the hash algorithm.
;  Can be  "sha1", "sha256", "sha384", "sha512", "md2", "md5", "haval", "ripemd128", "ripemd160","ripemd256", or "ripemd320".
$oCrypt.HashAlgorithm = "sha256"

Local $oHashBytes
$oHashBytes = $oCrypt.HashFile("qa_data/jpg/starfish.jpg")

;  Let's examine the hash as a hex string.
$oSb = ObjCreate("Chilkat.StringBuilder")
$oSb.AppendEncoded($oHashBytes,"hex")
ConsoleWrite("SHA256 hash = " & $oSb.GetAsString() & @CRLF)
