VerifyOptions
• Optional algorithms: string[]
A list of accepted JWS "alg" (Algorithm) Header Parameter values. By default all "alg" (Algorithm) values applicable for the used key/secret are allowed. Note: "none" is never accepted.
• Optional crit: Object
An object with keys representing recognized "crit" (Critical) Header Parameter
names. The value for those is either true or false. true when the
Header Parameter MUST be integrity protected, false when it's irrelevant.
This makes the "Extension Header Parameter "${parameter}" is not recognized" error go away.
Use this when a given JWS/JWT/JWE profile requires the use of proprietary non-registered "crit" (Critical) Header Parameters. This will only make sure the Header Parameter is syntactically correct when provided and that it is optionally integrity protected. It will not process the Header Parameter in any way or reject if the operation if it is missing. You MUST still verify the Header Parameter was present and process it according to the profile's validation steps after the operation succeeds.
The JWS extension Header Parameter b64 is always recognized and processed
properly. No other registered Header Parameters that need this kind of
default built-in treatment are currently available.
