cryptomancer

A comprehensive cryptographic library for Crystal providing implementations of fundamental cryptographic algorithms following industry standards and RFC specifications.

Overview

cryptomancer is a pure Crystal implementation of essential cryptographic primitives, designed to be fast, secure, and easy to use. The library focuses on providing well-tested, standards-compliant implementations of hash functions, ciphers, and other cryptographic building blocks.

Features

• Standards-compliant: Implements algorithms according to RFC specifications and industry standards
• Pure Crystal: No external dependencies, written entirely in Crystal
• Well-documented: Comprehensive documentation with examples and use cases
• Type-safe: Leverages Crystal's type system for safer cryptographic operations
• Performance-focused: Optimized implementations for production use
• Extensible: Clean architecture for adding new algorithms

What's Included

• Hash Functions: Cryptographic hash algorithms (BLAKE2b, BLAKE2bp, and more coming)
• Ciphers: Symmetric encryption algorithms (planned)
• Digital Signatures: Signature algorithms (planned)
• Key Exchange: Key agreement protocols (planned)

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     cryptomancer:
       github: qwd666/cryptomancer

2. Run shards install

Usage

require "cryptomancer"

Available Classes
