## What it is
A mostly pure-Rust library implementing many common cryptographic algorithms such as AES, SHA-2, ChaCha20, and Ed25519. It aims for practical, auditable implementations with minimal assembly, though it has not been formally audited.

## Use cases
- encrypt and decrypt data with AES in Rust
- compute SHA-2 or SHA-3 hashes in pure Rust
- sign and verify messages with Ed25519
- derive keys with PBKDF2 or Scrypt
- use stream ciphers like ChaCha20 or Salsa20 in Rust

## When to choose
- you need a broad set of crypto algorithms in a single pure-Rust crate
- you want auditable Rust source rather than C bindings
- you need legacy algorithms like MD5, RC4, or Blowfish

## When to avoid
- you need formally audited, production-grade security guarantees
- you only need modern primitives - the RustCrypto ecosystem crates are better maintained
- you require constant-time guarantees verified by experts

## Facets
- artifact type: library
- maturity: maintenance
- function: cryptography, security
- domain: security, developer-tools
- platform: rust, windows
- tags: crypto, aes, sha2, chacha20, ed25519, pure-rust, linux, macos
