(AutoIt) Compute Glacier SHA256 Tree Hash of a File
Computes the Amazon Glacier SHA256 tree hash for a file.
Note: This example requires Chilkat v9.5.0.78 or greater.
; This example requires the Chilkat API to have been previously unlocked.
; See Global Unlock Sample for sample code.
$oCrypt = ObjCreate("Chilkat.Crypt2")
; For more information about Amazon Glacier tree hashes, see Computing Glacier Checksums
; Chilkat added the "sha256-tree-hash" algorithm in v9.5.0.78 to make it easy to compute the Glacier tree hash checksum
; of a file or from bytes in memory.
$oCrypt.HashAlgorithm = "sha256-tree-hash"
; Return the hash in lowercase hexidecimal format.
$oCrypt.EncodingMode = "hexlower"
Local $sTreeHashHex = $oCrypt.HashFileENC("qa_data/jpg/penguins.jpg")
ConsoleWrite("SHA256 tree hash = " & $sTreeHashHex & @CRLF)
