Crate hiae 

HiAE - High-throughput Authenticated Encryption

This crate provides an implementation of the HiAE (High-throughput Authenticated Encryption) algorithm as specified in the IETF Internet-Draft.

HiAE is designed for high-performance authenticated encryption with cross-platform efficiency, particularly optimized for both ARM NEON and x86-64 AES-NI architectures.

Features

• High Performance: Leverages platform-specific SIMD instructions (ARM NEON, x86-64 AES-NI)
• Security: 256-bit keys, 128-bit nonces and tags, constant-time operations
• Cross-Platform: Optimized for both ARM and x86 architectures
• Memory Safe: Implemented in Rust with secure memory management
• No-std Compatible: Can be used in embedded environments

Usage

use hiae::{encrypt, decrypt};

let key = [0u8; 32];      // 256-bit key
let nonce = [0u8; 16];    // 128-bit nonce
let plaintext = b"Hello, world!";
let aad = b"additional data";

// Encrypt
let (ciphertext, tag) = encrypt(plaintext, aad, &key, &nonce)?;

// Decrypt
let decrypted = decrypt(&ciphertext, &tag, aad, &key, &nonce)?;
assert_eq!(decrypted, plaintext);

Enums

Error

Errors that can occur during HiAE operations.

Functions

decrypt
