This package contains a very thin Python wrapper for libdeflate.

pyzopfli is a straight forward wrapper around the ZlibCompress method of the the zopfli library.

The Python keyring lib provides a easy way to access the system keyring service from python. It can be used in any application that needs safe password storage.

This package provides a Python implementation of the JOSE protocol (Javascript Object Signing and Encryption).

Paramiko is a python implementation of the SSHv2 protocol, providing both client and server functionality. While it leverages a Python C extension for low level cryptography (PyCrypto), Paramiko itself is a pure Python interface around SSH networking concepts.

This package provides a pure Python implementation of the DES and TRIPLE DES encryption algorithms.

This is a set of python bindings for keyutils, a key management suite that leverages the infrastructure provided by the Linux kernel for safely storing and retrieving sensitive information in your programs.

Certifi is a Python library that contains a CA certificate bundle, which is used by the Requests library to verify HTTPS requests.

This package provides Cython bindings for MurmurHash2.

M2Crypto is a complete Python wrapper for OpenSSL featuring RSA, DSA, DH, EC, HMACs, message digests, symmetric ciphers (including AES); TLS functionality to implement clients and servers; HTTPS extensions to Python's httplib, urllib, and xmlrpclib; unforgeable HMAC'ing AuthCookies for web session management; FTP/TLS client and server; S/MIME; M2Crypto can also be used to provide TLS for Twisted. Smartcards supported through the Engine interface.

service_identity aspires to give you all the tools you need for verifying whether a certificate is valid for the intended purposes. In the simplest case, this means host name verification. However, service_identity implements RFC 6125 fully and plans to add other relevant RFCs too.

argon2-cffi-bindings provides low-level CFFI bindings to the official implementation of the Argon2 password hashing algorithm.

Privy is a small and fast utility for password-protecting secret data such as API keys, cryptocurrency wallets, or seeds for digital signatures.

PyNaCl is a Python binding to libsodium, which is a fork of the Networking and Cryptography library. These libraries have a stated goal of improving usability, security and speed.

Base58 and Base58Check implementation compatible with what is used by the Bitcoin network.

Keyrings in this package may have security risks or other implications. These backends were extracted from the main keyring project to make them available for those who wish to employ them, but are discouraged for general production use. Include this module and use its backends at your own risk.

This is an easy-to-use implementation of ECDSA cryptography (Elliptic Curve Digital Signature Algorithm), implemented purely in Python. With this library, you can quickly create key pairs (signing key and verifying key), sign messages, and verify the signatures. The keys and signatures are very short, making them easy to handle and incorporate into other protocols.

Python module for generating objects that compute the Cyclic Redundancy Check.

This package provides a Python ECDSA library, optimized for speed but without C extensions.

This package provides Ed25519 public-key signatures in Python.

Currently, PGPy can load keys and signatures of all kinds in both ASCII armored and binary formats.

It can create and verify RSA, DSA, and ECDSA signatures, at the moment. It can also encrypt and decrypt messages using RSA and ECDH.

This package provides a Python implementation of the HMAC Key Derivation function (HKDF) defined in RFC 5869.

trustme is a tiny Python package that does one thing: it gives you a fake certificate authority (CA) that you can use to generate fake TLS certs to use in your tests.

This is a python port of libaxolotl-android. This is a ratcheting forward secrecy protocol that works in synchronous and asynchronous messaging environments.
