A promise that resolves to the generated compact JWS.

Throws
Will throw an error if the specified algorithm is not supported.

`Static` verify

verify(opts): Promise<string>
Verifies the integrity of a message or resource's signature.
Parameters
- opts: VerifyOptions
  The options required for verification.
