This article explains the fundamentals of symmetric encryption, presents Python examples for AES and DES using the pycryptodome library, demonstrates how to encrypt API request data, and outlines key management and performance considerations for secure API automation testing.
This tutorial walks readers through building a Python‑based file encrypter using the Pycryptodome library, covering AES‑CBC encryption, PBKDF2 key derivation, functions for encrypting and decrypting files, environment setup on Windows, macOS and Linux, and a simple driver script for testing.
This article explains how to install pycryptodome (or pycryptodomex) to perform SM2 signing and verification in Python, provides complete code examples, and offers guidance for ensuring compatibility with Java's Bouncy Castle SM2 implementation.
This article explains RSA asymmetric encryption, key pair generation, encryption/decryption limits, digital signing and verification, and provides a full Python implementation using PyCryptodome, complete with code snippets, base64 handling, and practical usage tips.
This article explains how to capture a video site's POST data with Fiddler, locate encrypted M3U8 stream URLs, and use Python 3 with the pycryptodome library to decrypt and download the video files for playback or conversion.
This article introduces Python's cryptographic capabilities, covering built‑in hashing with hashlib, key derivation with pbkdf2_hmac, and practical examples using third‑party libraries PyCryptodome and cryptography to perform MD5/SHA hashing, DES and RSA encryption/decryption, and secure file handling.
