baseid-did

The DID crate implements creation and resolution for did:key, did:web, and did:jwk methods.

Installation

[dependencies]
baseid-did = "0.1.0-alpha.1"

Create a DID

use baseid_core::types::KeyType;
use baseid_crypto::KeyPair;
use baseid_did::DidKeyResolver;

let kp = KeyPair::generate(KeyType::Ed25519)?;
let doc = DidKeyResolver::create(&kp.public)?;
println!("DID: {}", doc.id);

Resolve a DID

use baseid_did::resolve;

// did:key resolves locally
let doc = resolve("did:key:z6MkhaXg...").await?;

// did:web fetches over HTTPS
let doc = resolve("did:web:example.com").await?;

pub struct DidDocument {
    pub id: String,
    pub verification_method: Vec<VerificationMethod>,
    pub authentication: Vec<String>,
    pub assertion_method: Vec<String>,
    pub key_agreement: Vec<String>,
}
