Expand description

Types which are able to verify DNS based signatures

Required Methods§

source

fn algorithm(&self) -> Algorithm

Return the algorithm which this Verifier covers

source

fn key(&self) -> ProtoResult<PublicKeyEnum<'_>>

Return the public key associated with this verifier

Provided Methods§

source

fn verify(&self, hash: &[u8], signature: &[u8]) -> ProtoResult<()>

Verifies the hash matches the signature with the current key.

Arguments
  • hash - the hash to be validated, see rrset_tbs
  • signature - the signature to use to verify the hash, extracted from an RData::RRSIG for example.
Return value

True if and only if the signature is valid for the hash. false if the key.

source

fn verify_message<M: BinEncodable>( &self, message: &M, signature: &[u8], sig0: &SIG ) -> ProtoResult<()>

Verifies a message with the against the given signature, i.e. SIG0

Arguments
  • message - the message to verify
  • signature - the signature to use for validation
Return value

true if the message could be validated against the signature, false otherwise

source

fn verify_rrsig( &self, name: &Name, dns_class: DNSClass, sig: &RRSIG, records: &[Record] ) -> ProtoResult<()>

Verifies an RRSig with the associated key, e.g. DNSKEY

Arguments
  • name - name associated with the rrsig being validated
  • dns_class - DNSClass of the records, generally IN
  • sig - signature record being validated
  • records - Records covered by SIG

Object Safety§

This trait is not object safe.
