This package provides another Scrypt module for Python.

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 Cython bindings for MurmurHash2.

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

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 pure Python implementation of the blurhash algorithm.

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.

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.

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.

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 library handles the low-level details of NTLM authentication for use in authenticating with a service that uses NTLM. It will create and parse the 3 different message types in the order required and produce a base64 encoded value that can be attached to the HTTP header.

The goal of this library is to offer full NTLM support including signing and sealing of messages as well as supporting MIC for message integrity and the ability to customise and set limits on the messages sent. Please see Features and Backlog for a list of what is and is not currently supported.

This is a Python implementation of the zxcvbn library created at Dropbox. The original library, written for JavaScript, can be found here. This port includes features such as:

1. Accepts user data to be added to the dictionaries that are tested against (name, birthdate, etc.)

2. Gives a score to the password, from 0 (terrible) to 4 (great).

3. Provides feedback on the password and ways to improve it.

4. Returns time estimates on how long it would take to guess the password in different situations.

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.

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.

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 Python implementation of the SPAKE2 Password-Authenticated Key Exchange algorithm.

This package provides Python bindings for the Rust crate of blake3, a cryptographic hash function.

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.

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

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

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.

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