LibTomCrypt is a fairly comprehensive, modular and portable cryptographic toolkit that provides developers with a vast array of well known published block ciphers, one-way hash functions, chaining modes, pseudo-random number generators, public key cryptography and a plethora of other routines.

Simple and secure hashing in Swift with the SipHash algorithm

This is an implementation of RSA signing for MicroPython. It's writter in pure Python, and based on python-rsa version 4.0.

A full-featured Swift library for JOSE standards with first-class support for CryptoKit keys, providing JWS, JWT, SD-JWT, and JWE with signing, encryption, and JWK key management.

BCrypt.Net - Bringing updates to the original bcrypt package

This is a header-only library, as such most of its functional documentation is contained within the "header section" of the source code in the form of comments. It is highly recommended that you read said documentation before using this library.

Extensible JOSE library for Scala

MicroPython bindings for ECDSA keys basic functionality and x509 cert/csr utilities. Supports both PEM and DER formats

Welcome to the Ada Crypto Library (ACL) aka libadacrypt This library is an ongoing project that provides the Ada community to strong cryptography primitives and schemes, focused to ensure data confidentiality and data integrity.

Mbed TLS is an open-source TLS and DTLS library with a small footprint, designed for embedded systems and IoT devices. It provides a portable cryptographic library that includes symmetric ciphers, hashing, and public-key cryptography, along with a reference implementation of the PSA Cryptography API for standardized cryptographic operations across platforms. The library also offers X.509 certificate management for parsing, validating, and managing certificate chains in secure communications. The library is built around a platform abstraction layer that decouples it from OS-specific services t

Library and command line tool to detect SHA-1 collision in a file

Basic implementations of standard cryptography algorithms, like AES and SHA-1.

xxHash is a high-performance, non-cryptographic hash library designed for rapid checksum generation and data integrity verification. It functions as an incremental hashing engine, allowing for the processing of large or streaming data inputs by maintaining a persistent internal state across sequential chunks. The library is engineered as a computational framework that maximizes throughput by utilizing wide CPU registers and branchless instruction pipelining. It achieves high-speed performance by aligning data access with CPU cache lines and employing multi-stage mixing functions that ensure c

OpenSSL D interface

A (mostly) pure-Rust implementation of various cryptographic algorithms.

This project implements the Keccak family of sponge functions and related constructions using the SPARK 2014 programming language, with static proof of type safety and good performance.

Implementation of Fletcher_16 sum. Only computation of the sum is performed.

Implementation of hashids (http://hashids.org) in Python. Compatible with Python 2 and Python 3

php-encryption is a symmetric encryption library for PHP that provides tools for authenticated encryption and key derivation to ensure data confidentiality and integrity. It functions as a cryptography toolkit that wraps complex primitives into simplified interfaces to prevent common implementation errors. The library includes a binary-safe ciphertext serializer to maintain data structure during storage and transmission, as well as a password-based key derivation tool that transforms low-entropy passwords into cryptographically strong keys through iterative processes. The project covers a br

I'm thrilled to announce that enigmapython, my powerful Enigma machine emulator, is now available on MicroPython! 🚀

Crystal wrapper for the libsodium crypto API

A minimal bitcoin library for MicroPython and Python 3.10+ with a focus on embedded systems.

Micropython package for doing fast rsa and elliptic curve cryptography, specifically digital signatures. ECDSA API design inspired from fastecdsa and implementation based on tomsfastmath.
