▸ EmbeddedJWK(protectedHeader?, token?): Promise<CryptoKey>

Resolves a verification key from an embedded "jwk" (JSON Web Key) Header Parameter. This key resolver opts JWS and JWT verification into trusting a public key supplied by the token. Use the verification function's algorithms option to restrict accepted algorithms.

This function is exported (as a named export) from the main 'jose' module entry point as well as from its subpath export 'jose/jwk/embedded'.

Parameters

Returns

Promise<CryptoKey>

The public key from the JWS "jwk" (JSON Web Key) Header Parameter.
