Keyczar - Toolkit for safe and simple cryptography

  •        2413

KeyczarKeyczar is an open source cryptographic toolkit designed to make it easier and safer for devlopers to use cryptography in their applications. Keyczar supports authentication and encryption with both symmetric and asymmetric keys. Keyczar was originally developed by members of the Google Security Team.
Keyczar is designed to be open, extensible, and cross-platform compatible. It is not intended to replace existing cryptographic libraries like OpenSSL, PyCrypto, or the Java JCE, and in fact is built on these libraries.

Cryptography - Package designed to expose cryptographic primitives and recipes to Python developers

  •    Python

cryptography is a package which provides cryptographic recipes and primitives to Python developers. Our goal is for it to be your "cryptographic standard library". It supports Python 2.7, Python 3.4+, and PyPy 5.3+. cryptography includes both high level recipes and low level interfaces to common cryptographic algorithms such as symmetric ciphers, message digests, and key derivation functions. For example, to encrypt something with cryptography's high level symmetric encryption recipe.
