Struct MessageVerifier

pub struct MessageVerifier { /* private fields */ }

A MessageVerifier performs the verifications needed for a signed message.

Implementations

impl MessageVerifier

pub fn parse<P>( message: &impl SignedMessage, alg: Option<Algorithm>, pick: P, ) -> Result<Self, ImplementationError>

where P: Fn(&(Key, InnerList)) -> bool,

Parse a message into a structure that is ready for verification against an external key with a suitable algorithm. If alg is not set, a default will be chosen from the alg parameter. pick is a predicate enabling you to choose which message label should be considered as the message to verify - if it is known only one signature is in the message, simply return true.

Errors

Returns ImplementationErrors relevant to verifying and parsing.

pub fn get_details(&self) -> ParameterDetails

Retrieve the parsed ParameterDetails from the message. Useful for logging information about the message.

pub fn verify( self, keyring: &KeyRing, key_id: Option<Thumbprint>, ) -> Result<SignatureTiming, ImplementationError>

Verify the messsage, consuming the verifier in the process. If key_id is not supplied, a key ID to fetch the public key from keyring will be sourced from the keyid parameter within the message. Returns information about how long verification took if successful.

Errors

Returns ImplementationErrors relevant to verifying and parsing.

pub fn is_expired(&self) -> Option<bool>

Whether or not this message is expired, based on its expires value.

Trait Implementations

impl Clone for MessageVerifier

fn clone(&self) -> MessageVerifier

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MessageVerifier

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
