Crate ma_did 

ma-did

DID and message primitives for the did:ma: method.

This crate provides everything needed to create, sign, and verify DID documents and encrypted actor-to-actor messages.

Quick Start — Identity

use ma_did::{generate_identity, Did};

// Generate a complete identity (keys + signed document)
let ipns = "k51qzi5uqu5dj9807pbuod1pplf0vxh8m4lfy3ewl9qbm2s8dsf9ugdf9gedhr";
let identity = generate_identity(ipns).unwrap();

// The document is already signed and valid
identity.document.verify().unwrap();
identity.document.validate().unwrap();

// Serialize to JSON or CBOR
let json = identity.document.marshal().unwrap();
let cbor = identity.document.to_cbor().unwrap();

Quick Start — Messages

use ma_did::{generate_identity, Message, SigningKey, Did};

let alice = generate_identity("k51qzi5uqu5dj9807pbuod1pplf0vxh8m4lfy3ewl9qbm2s8dsf9ugdf9gedhr").unwrap();
let bob = generate_identity("k51qzi5uqu5dl96qbq93mwl5drvk2z83fk4s6h4n7xgqnwrxlscs11i1bja7uk").unwrap();

// Reconstruct signing key from stored private key bytes
let alice_sign_url = Did::new_url(&alice.subject_url.ipns, None::<String>).unwrap();
let alice_signing_key = SigningKey::from_private_key_bytes(
    alice_sign_url,
    hex::decode(&alice.signing_private_key_hex).unwrap().try_into().unwrap(),
).unwrap();

// Create a signed message
let msg = Message::new(
    alice.document.id.clone(),
    bob.document.id.clone(),
    "text/plain",
    b"hello".to_vec(),
    &alice_signing_key,
).unwrap();

// Verify message signature against sender's document
msg.verify_with_document(&alice.document).unwrap();

// Encrypt for recipient as an Envelope
let envelope = msg.enclose_for(&bob.document).unwrap();
