Adapters

Choose the implementation explicitly

WeaveIdentityAdapter defines asynchronous key generation, identity derivation, signing, verification, parsing and control checks. create_agent_identity returns (KeyPair, Identity). Signing uses the keypair; verification uses the identity.

use weave_identity::{Ed25519Adapter, WeaveIdentityAdapter};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let adapter = Ed25519Adapter::new();
    let (keypair, identity) = adapter.create_agent_identity(Some("example")).await?;
    let message = b"adapter round-trip";
    let signature = adapter.sign(&keypair, message).await?;
    assert!(adapter.verify(&identity, message, &signature).await?);
    println!("{}", identity.id());
    Ok(())
}

There are two distinct Ed25519Adapter types: the resolver/delegation implementation exported by weave_identity, and the separate weave_identity_ed25519 package with parser/formatter configuration. Select the qualified import matching the behavior you need. The trait does not automatically supply HSM, FROST, chain registration or payload canonicalization.
