KT2

KeyTree2 (KT2) is a 2nd generation, quantum-resistant cryptographic library used for Atlas' Data Access Layer. It is effectively a wrapper around multiple cryptographic primitives:

• Symmetric encryption: AES-256-GCM from ring
• Signatures: modified Dilithium3 from CRYSTALS (we've reduced SHAKE256's rounds down to 12), taken from crystals-dilithium
• Hashes: BLAKE3 from blake3
• Key encapsulation: Kyber768 from CRYSTALS from safe_pqc_kyber

Build

cargo build --release

How to use

use d3::Keypair;

let keypair = Keypair::generate(Some(&seed));
let sk = keypair.secret;
// pk is also available as keypair.public
let signature = keypair.sign(&msg);
// public key can now be separately derived from the secret key
let pk = PublicKey::from_sk(&sk);
let is_verified = pk.verify(&msg, &signature);

Test

cargo test
