Expand description

A verifier for JWS messages.

Required Methods

Verify the signature of a JWS message.

This function needs access to the decoded message headers in order to determine which MAC algorithm to use. It also needs access to the base64-url encoded parts to verify the signature.

If the signature is invalid, the function should return a Error::InvalidSignature error. If the algorithm is not supported by the verifier, it should return a Error::UnsupportedMacAlgorithm error. It may also report any of the other supported error variants.

Args:
  • protected_header: The parsed protected header, if any.
  • unprotected_header: The parsed unprotected header, if any.
  • encoded_header: The base64-url encoded protected header, needed to compute the MAC. If there is no protected header, this is an empty slice.
  • encoded_payload: The base64-url encoded payload, needed to compute the MAC.
  • signature: The signature associated with the message, should be tested against the computed MAC.

Provided Methods

Create a new verifier that accepts a message if either this or the other verifier does.

Create a new verifier that accepts a message if both this and the other verifier does.
