Simple and secure asymmetric cryptography: signing and encryption using Ed25519
no_std SHA512-crypt ($6$) password hashing, ported from Ulrich Drepper's reference implementation. Pluggable crypto backend (aws-lc, BoringSSL, OpenSSL, or RustCrypto) selected by feature.
A flexible binary format for storing and streaming structured data as packets with CRC protection and recoverability from corruption. Built for extensibility and robustness.
A compact and intuitive library that wraps the crypt_guard crate, making its core functionalities easily accessible and manageable. This library provides essential cryptographic operations, including key generation, encryption, decryption, and digital signing, with support for multiple key variants such as Falcon and Dilithium. Its streamlined interface ensures a straightforward integration into your projects, offering robust security mechanisms with minimal complexity.
Implementation of Playfair, Two square and Four square cipher
Pure Rust implementation of the SHA-crypt password hashing algorithm based on SHA-256/SHA-512 as implemented by the POSIX crypt C library, including support for generating and verifying password hash strings in the Modular Crypt Format
Library for encrypting and decrypting secrets within the AWS ecosystem.
Ultra secure encryption/decryption tool using Rust + libsodium with zero secret leakage.
The Crypt library is a pure-ruby implementation of a number of popular encryption algorithms. Block cyphers currently include Blowfish, GOST, IDEA, and Rijndael (AES). Cypher Block Chaining (CBC) has been implemented, and unicode is supported.
Transparent ActiveRecord encryption
Performs the UNIX crypt(3) algorithm using DES (standard 13 character passwords), MD5 (starting with $1$), SHA256 (starting with $5$) and SHA512 (starting with $6$)
ISAAC is a fast, cryptographically secure pseudo random number generator with strong statistical properties. This gem provides both a pure Ruby and a C extension based implementation which conforms to the Ruby 2 api for Random, with some enhancements. So, you should be able to use it as a drop in replacement for Ruby's (Mersenne Twister based) PRNG.
A high-level encryption toolkit providing AES-256-GCM encryption and decryption, key rotation, envelope encryption, PBKDF2 key derivation, secure random generation, configurable hashing (SHA-256/384/512), and constant-time string comparison using Ruby's built-in OpenSSL.
The crypt-rot13 library provides an interface for a simple character substitution cipher known as ROT13, a variation on the Caesar cipher.
