Module did 

NDN DID method — encode NDN names as W3C Decentralized Identifiers and resolve DID Documents over the NDN network or via bridged methods.

did:ndn encoding

A did:ndn DID is the base64url (no padding) encoding of the complete NDN Name TLV wire format, including the outer 07 <length> bytes:

did:ndn:<base64url(Name TLV)>

This single form handles all NDN names unambiguously — GenericNameComponents, BLAKE3_DIGEST zone roots, versioned components, etc. — without type-specific special cases. See encoding for backward-compat parsing of older forms.

Resolution

Use UniversalResolver to resolve any supported DID method:

use ndn_security::did::{UniversalResolver, KeyDidResolver};

let resolver = UniversalResolver::new();
let doc = resolver.resolve_document("did:key:z6Mkfriq3r5SBo8EdoHpBVQBjEPdmBLWGcWHMU3KCi4bXD3m").await?;
println!("{}", doc.id);

DID URL dereferencing

use ndn_security::did::{DidUrl, deref_did_url};
use ndn_security::did::document::DidDocument;

let url = DidUrl::parse("did:ndn:com:acme:alice#key-0").unwrap();
if let Some(resource) = deref_did_url(&url, doc) {
    println!("found resource for fragment");
}
