M2Crypto

M2Crypto is a comprehensive cryptography and SSL toolkit for Python, acting as a wrapper around the well-established OpenSSL library via SWIG. It provides functionalities for RSA, DSA, DH, HMACs, message digests, symmetric ciphers including AES, and TLS for client and server implementations. The library is currently in maintenance mode, with its developers recommending migration to more modern alternatives like PyCA/cryptography. The latest version, 0.47.0, was released on February 8, 2026. While not on a fixed schedule, releases appear periodically.
