attachMethodRelationship()

attachMethodRelationship(didUrl, relationship): boolean

verifyJws()

verifyJws(jws, options, signatureVerifier?, detachedPayload?): DecodedJws

Decodes and verifies the provided JWS according to the passed options and signatureVerifier. If a signatureVerifier is provided it will be used when verifying decoded JWS signatures, otherwise a default verifier capable of handling the EdDSA, ES256, ES256K algorithms will be used.

Regardless of which options are passed the following conditions must be met in order for a verification attempt to take place.

The JWS must be encoded according to the JWS compact serialization.
The kid value in the protected header must be an identifier of a verification method in this DID document, or set explicitly in the options.

Parameters

detachedPayload?

null | string

Returns

DecodedJws
