Open-source alternatives to Gocrypto

Stream encryption & decryption with libsodium and protobuf

Easy to use cryptographic framework for data protection: secure messaging with forward secrecy and secure data storage. Has unified APIs across 14 platforms.

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

Libsodium is a portable, C-based cryptographic library that provides a collection of modern primitives for encryption, decryption, digital signatures, password hashing, and secure key exchange. It is designed to facilitate secure communication and data integrity across diverse hardware architectures and operating systems. The library distinguishes itself by utilizing constant-time primitive execution to prevent side-channel attacks and employing memory-hard algorithms to increase the difficulty of brute-force password attacks. It abstracts complex mathematical operations into simplified inter

This is a symmetric cryptography library written in C that provides a portable implementation of the Advanced Encryption Standard. It functions as a block cipher implementation supporting 128, 192, and 256 bit key sizes for encrypting and decrypting data. The library includes an AES cipher mode provider that supports electronic codebook, cipher block chaining, and counter modes. These operational modes are decoupled from the core block transformation to allow for different encryption patterns. The implementation utilizes static memory allocation and table-based substitution to avoid dynamic

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.

A library designed to generate cryptographically strong random numbers suitable for managing data such as passwords, account authentication, security tokens, and related secrets.

Clj-crypto is a wrapper for Bouncy Castle which allows you to easily use cryptography in your clojure app.

Modern Cryptography Suite in C++17

This project is a comprehensive cryptographic toolkit that provides a collection of standard security algorithms and protocols for implementing data encryption and network communication. It serves as a foundational library for securing software applications through a wide range of cryptographic functions. The architecture is defined by a modular provider system that allows for the dynamic loading of external cryptographic implementations without requiring modifications to the core application binary. It supports metadata-driven algorithm querying, which resolves security primitives by matchin
