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

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.

OMEMO cryptography library that was forked from python-axolotl.

This package contains test vectors for the cryptography package.

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.

This package provides a Elliptic Curve Library in pure Python.

This package provides a small library, built on top of pyOpenSSL, which allows for creating a custom certificate authority (CA) certificate, and generating on-demand dynamic host certs using that CA certificate. It is most useful for use with a man-in-the-middle HTTPS proxy, for example, for recording or replaying web content.

This is a low-level, pure Python DBus protocol client. It has an I/O-free core, and integration modules for different event loops.

This package provides Ed25519 public-key signatures in Python.

libnacl is used to gain direct access to the functions exposed by NaCl library via libsodium. It has been constructed to maintain extensive documentation on how to use NaCl as well as being completely portable.

This Python package is a high-level wrapper for Kerberos (GSSAPI) operations. The goal is to avoid having to build a module that wraps the entire Kerberos.framework, and instead offer a limited set of functions that do what is needed for client/server Kerberos authentication based on <http://www.ietf.org/rfc/rfc4559.txt>.

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

This is a python wrapper for the curve25519 library with ed25519 signatures. The C code was pulled from libaxolotl-android. At the moment this wrapper is meant for use by python-axolotl.

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

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

This package is a set of Python bindings for the scrypt key derivation function.

Python-oscrypto is a compilation-free encryption library which integrates with the encryption library that is part of the operating system. It supports TLS (SSL) sockets, key generation, encryption, decryption, signing, verification and KDFs using the OS crypto libraries.

Certipy was made to simplify the certificate creation process. To that end, certipy exposes methods for creating and managing certificate authorities, certificates, signing and building trust bundles.

Python-RSA is a pure-Python RSA implementation. It supports encryption and decryption, signing and verifying signatures, and key generation according to PKCS#1 version 1.5. It can be used as a Python library as well as on the command line.

asn1crypto is an ASN.1 parser and serializer with definitions for private keys, public keys, certificates, CRL, OCSP, CMS, PKCS#3, PKCS#7, PKCS#8, PKCS#12, PKCS#5, X.509 and TSP.

This package provides another Scrypt module for Python.

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.

Pyu2f is a Python-based U2F host library. It provides functionality for interacting with a U2F device over USB.

This package provides Cython bindings for MurmurHash2.
