From Python 3.9 to 3.12 the standard library adds a suite of ready‑to‑use functions—such as str.removeprefix/removesuffix, math.dist, math.comb, zoneinfo, hashlib.blake2b, and tomllib—that eliminate repetitive code, boost performance, and let developers focus on core logic.
This article explains how Python's hashlib and hmac modules can be applied in API automation to compute hashes, generate salted password hashes, create HMACs, verify data integrity, encrypt sensitive information, and produce secure tokens, providing ten practical code examples.
Learn how to automatically identify and delete duplicate files in Python by first comparing file sizes and then using MD5 hashes, with a concise script that leverages pathlib for path handling and hashlib for checksum calculation, offering a fast, reliable solution for everyday file management tasks.
This article introduces Python’s hashlib module, explains the principles and characteristics of common hash algorithms such as MD5, SHA‑1, SHA‑224, SHA‑256, SHA‑384, and SHA‑512, demonstrates how to compute their digests with code examples, and shows simple key‑based encryption techniques.
This article explains Python's hashlib module, demonstrates basic MD5 hashing, shows how to compute file checksums, and discusses secure password storage with salting techniques, providing complete code examples for each use case.
