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 contains a pure-Python implementation of the AES block cipher algorithm and the common modes of operation (CBC, CFB, CTR, ECB and OFB).

The Stateless OpenPGP Command-Line Interface (or sop) is a specification that encourages OpenPGP implementers 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.

This package contains test vectors for the cryptography package.

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

This package provides utilities for generating and using Bitcoin Hierarchical Deterministic wallets (BIP0032).

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.

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).

Argon2 is a secure password hashing algorithm. It is designed to have both a configurable runtime as well as memory consumption. This means that you can decide how long it takes to hash a password and how much memory is required.

This package provides a reference implementation of the SLIP-0010 (see: https://github.com/satoshilabs/slips, slip-0010.md) specification,which generalizes the BIP-0032 (see: https://github.com/bitcoin/bips/tree, bip-0032.mediawiki) derivation scheme for private and public key pairs in hierarchical deterministic wallets for the curves secp256k1, NIST P-256, ed25519 and curve25519.

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

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.

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

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

This library allows you to write entries to a KeePass database. It supports KDBX3 and KDBX4.

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.

PyCryptodome is a self-contained Python package of low-level cryptographic primitives. It's not a wrapper to a separate C library like OpenSSL. To the largest possible extent, algorithms are implemented in pure Python. Only the pieces that are extremely critical to performance (e.g., block ciphers) are implemented as C extensions.

You are expected to have a solid understanding of cryptography and security engineering to successfully use these primitives. You must also be able to recognize that some are obsolete (e.g., TDES) or even insecure (RC4).

It provides many enhancements over the last release of PyCrypto (2.6.1):

• Authenticated encryption modes (GCM, CCM, EAX, SIV, OCB)

• Accelerated AES on Intel platforms via AES-NI

• First-class support for PyPy

• Elliptic curves cryptography (NIST P-256 curve only)

• Better and more compact API (nonce and iv attributes for ciphers, automatic generation of random nonces and IVs, simplified CTR cipher mode, and more)

• SHA-3 (including SHAKE XOFs) and BLAKE2 hash algorithms

• Salsa20 and ChaCha20 stream ciphers

• scrypt and HKDF

• Deterministic (EC)DSA

• Password-protected PKCS#8 key containers

• Shamir’s Secret Sharing scheme

• Random numbers get sourced directly from the OS (and not from a CSPRNG in userspace)

• Cleaner RSA and DSA key generation (largely based on FIPS 186-4)

• Major clean-ups and simplification of the code base

This package provides drop-in compatibility with PyCrypto. It is one of two PyCryptodome variants, the other being python-pycryptodomex.

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

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

cryptography is a package which provides cryptographic recipes and primitives to Python developers. It aims to be the “cryptographic standard library” for Python. The package includes both high level recipes, and low level interfaces to common cryptographic algorithms such as symmetric ciphers, message digests and key derivation functions.

This package provides async versions of Kivy functions to avoid the callback-heavy mode of interaction typical in some Kivy applications.

This package provides Kivy widgets that approximate Google's Material Design spec without sacrificing ease of use or application performance.

ModernGL is a Python wrapper over OpenGL Core. ModernGL simplifies the creation of graphics applications like scientific simulations, games or user interfaces. Usually, acquiring in-depth knowledge of OpenGL requires a steep learning curve. In contrast, ModernGL is easy to learn and use. ModernGL is capable of rendering with high performance and quality, with less code written.

Pyglet is a Python library for developing games and other visually-rich applications. It supports windowing, user interface event handling, Joysticks, OpenGL graphics, loading images and videos, playing sounds and music.
