Test vectors

DID.is is tested against published vectors from the specifications it implements. You can use the same vectors to check your own implementation, or to compare its output with DID.is.

did:key

The did:key specification example key:

curl https://did.is/api/v1/resolve/did:key:z6MkhaXgBZDvotDkL5257faiztiGiC2QtKLGpbnnEGta2doK

Expected: verdict.outcome is RESOLVED, one Ed25519 Multikey verification method, and these dimension states:

Dimension	State
integrity	SELF_CERTIFYING
keys	ESTABLISHED
control	SELF_CERTIFYING
origin	NOT_APPLICABLE
transport	NOT_APPLICABLE
history	NOT_APPLICABLE
organization	NOT_ESTABLISHED

Data Integrity: eddsa-jcs-2022

W3C Data Integrity EdDSA Cryptosuites v1.0, example in Appendix B (eddsa-jcs-2022):

• Credential id: urn:uuid:58172aac-d8ba-11ed-83dd-0b3aef56cc33
• Issuer: https://vc.example/issuers/5678
• Verification method: did:key:z6MkrJVnaZkeFzdQyMZu1cgjg7k1pZZ6pvBQ7XJPt4swbTQ2#z6MkrJVnaZkeFzdQyMZu1cgjg7k1pZZ6pvBQ7XJPt4swbTQ2
• proofValue: z2HnFSSPPBzR36zdDgK8PbEHeXbR56YF24jwMpt3R1eHXQzJDMWS93FCzpvJpwTWd3GAVFuUfjoJdcnTMuVor51aX

The proof verifies. Changing any claim (for example alumniOf) makes it invalid.
