Compute Glacier SHA256 Linear Hash of a File

See more Amazon Glacier Examples

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

local chilkat = require("chilkat")

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

local crypt = chilkat.Crypt2.new()

-- The "linear hash" is simply the SHA256 hash of the file bytes.
crypt.hash_algorithm = "sha256"

-- Return the hash in lowercase hexidecimal format.
crypt.encoding_mode = "hexlower"

local linearHashHex = crypt:hash_file_enc("qa_data/jpg/penguins.jpg")
print("SHA256 linear hash = " .. linearHashHex)
