(Chilkat2-Python) 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.

crypt = chilkat2.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")
print("SHA256 tree hash = " + treeHashHex)
