What format should I use to sign with DID?

Use Compact JWS (detached) with {"alg":"EdDSA","b64":false,"crit":["b64"],"kid":""} and sign the canonicalized post content (same text you would sign with OpenPGP).

Frequently Asked Questions

Common questions about Signed Posts

Once you've finished your post, click the three dots in the top-right corner of the Gutenberg editor. When the options menu opens, select "Copy all blocks." That is the content you should sign.

You can host it on any service that offers direct links and allows CORS (Cross-Origin Resource Sharing) access.

The plugin will display a warning message indicating that the signature doesn't match the content or the public key, which can be a sign of content tampering.

The impact on the server is minimal, as the verification is performed entirely in the visitor's browser. The only additional resource is the download of the public key, which is usually very small.

Use Compact JWS (detached) with {"alg":"EdDSA","b64":false,"crit":["b64"],"kid":"<your did#key>"} and sign the canonicalized post content (same text you would sign with OpenPGP).

In your User Profile, in the "Decentralized Identifiers (DID)" field. For did:web, ensure your did.json is hosted at https://<host>/.well-known/did.json.
