Encryption secures messages so that they can be verified as accurate and protected from interception. Python’s cryptography support includes
hashlib for generating signatures of message content using standard algorithms, such as MD5 and SHA, and
hmac for verifying that a message has not been altered in transmission.
Purpose Generate cryptographic hashes and message digests.
Python Version 2.5 and later
hashlib module deprecates the separate
sha modules and makes their API consistent. To work with a specific hash algorithm, use the appropriate constructor function to create a hash object. From there, the objects use the same API, no matter what algorithm is being used.
