Compute Glacier SHA256 Linear Hash of a File

See more Amazon Glacier Examples

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

require 'chilkat'

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

crypt = Chilkat::CkCrypt2.new()

# The "linear hash" is simply the SHA256 hash of the file bytes.
crypt.put_HashAlgorithm("sha256")

# Return the hash in lowercase hexidecimal format.
crypt.put_EncodingMode("hexlower")

linearHashHex = crypt.hashFileENC("qa_data/jpg/penguins.jpg")
print "SHA256 linear hash = " + linearHashHex + "\n";
