Arguments

:: CPRG g

=> g

Random number generator

-> JWS

JWS to sign

-> JWSHeader

Header for signature

-> JWK

Key with which to sign

-> (Either Error JWS, g)

JWS with new signature appended

Create a new signature on a JWS.

verifyJWS :: JWK -> JWS -> Bool

Verify a JWS.

Verification succeeds if any signature on the JWS is successfully validated with the given Key.
