(PowerShell) 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.
Add-Type -Path "C:\chilkat\ChilkatDotNet47-9.5.0-x64\ChilkatDotNet47.dll"
# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.
$crypt = New-Object 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.
$crypt.HashAlgorithm = "sha256-tree-hash"
# Return the hash in lowercase hexidecimal format.
$crypt.EncodingMode = "hexlower"
$treeHashHex = $crypt.HashFileENC("qa_data/jpg/penguins.jpg")
$("SHA256 tree hash = " + $treeHashHex)
