Expand description

A verifier for JWS messages.

Required Methods§

Source

fn verify( &self, protected_header: Option<&JsonObject>, unprotected_header: Option<&JsonObject>, encoded_header: &[u8], encoded_payload: &[u8], signature: &[u8], ) -> Result<()>

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§

Source

fn or<Other: Verifier>(self, other: Other) -> OrVerifier<Self, Other>

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

Source

fn and<Other: Verifier>(self, other: Other) -> AndVerifier<Self, Other>

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

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
