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

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.

MCUboot is a secure bootloader for 32-bit MCUs. This package provides a tool to securely sign firmware images for booting by MCUboot.

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.

PyOpenSSL is a high-level wrapper around a subset of the OpenSSL library.

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.

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.

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

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.

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.

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 package provides Cython bindings for MurmurHash2.

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

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

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.

python-secretstorage provides a way for securely storing passwords and other secrets. It uses D-Bus Secret Service API that is supported by GNOME Keyring (since version 2.30) and KSecretsService. SecretStorage supports most of the functions provided by Secret Service, including creating and deleting items and collections, editing items, locking and unlocking collections (asynchronous unlocking is also supported).

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

This package provides another Scrypt module for Python.

This package provides a Python implementation of the SPAKE2 Password-Authenticated Key Exchange algorithm.

Passlib is a password hashing library for Python 2 & 3, which provides cross-platform implementations of over 30 password hashing algorithms, as well as a framework for managing existing password hashes. It's designed to be useful for a wide range of tasks, from verifying a hash found in /etc/shadow, to providing full-strength password hashing for multi-user application.

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.

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

This package contains test vectors for the cryptography package.

The Stateless OpenPGP Command-Line Interface (or sop) is a specification that encourages OpenPGP implementors to provide a common, relatively simple command-line API for purposes of object security.

This Python module helps implementers build such a CLI from any implementation accessible to the Python interpreter.

It does not provide such an implementation itself -- this is just the scaffolding for the command line, which should make it relatively easy to supply a handful of python functions as methods to a class.
