Struct VerifierLookup 

Source 
pub struct VerifierLookup<'a> {
    index: CertLookup<'a>,
}
Expand description

An abstraction over a set of OpenpgpCert, to facilitate signature verification.

It can efficiently look up component keys that are appropriate for attempting validation of specific signatures.

Implementations§

Source§

impl<'a> VerifierLookup<'a>

Source

pub fn new(certs: &'a [OpenpgpCert]) -> Self

Creates a new VerifierLookup from a list of OpenpgpCerts.

Source

pub(crate) fn get_matching_verifiers( &self, signature: &OpenpgpSignature, ) -> Vec<(SignatureVerifier, &'a OpenpgpCert)>

Returns a list of [SignatureVerifier] and OpenpgpCert tuples, that are reasonable candidates for attempting to verify an OpenpgpSignature.

Looks up all component keys that match the IssuerFingerprint and/or Issuer subpackets in signature, and returns them as [SignatureVerifier] objects. For informational purposes, each [SignatureVerifier] is accompanied by a reference to the OpenpgpCert that contains it.

Callers of this function will usually want to validate signature with the returned [SignatureVerifier]s.

Source

fn candidate_certs(&self, signature: &Signature) -> Vec<&'a OpenpgpCert>

Returns a list of OpenpgpCerts that match either the IssuerFingerprint or Issuer subpackets in a [Signature].

All component keys of each OpenpgpCert are considered when matching against the IssuerFingerprint and Issuer subpackets of the signature. The returned OpenpgpCerts are deduplicated by their primary [Fingerprint].

§Note

The lookup does not enforce any semantics constraints. It does not guarantee validity of certificates or component keys for any particular purpose. Semantics checks must be performed separately, after this lookup.

Source

fn matches_issuer( signature: &OpenpgpSignature, verifier: &SignatureVerifier, ) -> bool

Checks if a [SignatureVerifier] matches any IssuerFingerprint or Issuer subpacket in an OpenpgpSignature.
