Expand description

Something that can verify a client certificate chain

Required methods

Returns the subject names of the client authentication trust anchors to share with the client when requesting client authentication.

Return None to abort the connection.

sni is the server name quoted by the client in its ClientHello; it has been validated as a proper DNS name but is otherwise untrusted.

Verify a certificate chain. presented_certs is the certificate chain from the client.

sni is the server name quoted by the client in its ClientHello; it has been validated as a proper DNS name but is otherwise untrusted.

Provided methods

Returns true to enable the server to request a client certificate and false to skip requesting a client certificate. Defaults to true.

Return Some(true) to require a client certificate and Some(false) to make client authentication optional. Return None to abort the connection. Defaults to Some(self.offer_client_auth()).

sni is the server name quoted by the client in its ClientHello; it has been validated as a proper DNS name but is otherwise untrusted.

Verify a signature allegedly by the given server certificate.

message is not hashed, and needs hashing during the verification. The signature and algorithm are within dss. cert contains the public key to use.

cert is the same certificate that was previously validated by a call to verify_server_cert.

If and only if the signature is valid, return HandshakeSignatureValid. Otherwise, return an error – rustls will send an alert and abort the connection.

This method is only called for TLS1.2 handshakes. Note that, in TLS1.2, SignatureSchemes such as SignatureScheme::ECDSA_NISTP256_SHA256 are not in fact bound to the specific curve implied in their name.

This trait method has a default implementation that uses webpki to verify the signature.

Verify a signature allegedly by the given server certificate.

This method is only called for TLS1.3 handshakes.

This method is very similar to verify_tls12_signature: but note the tighter ECDSA SignatureScheme semantics – eg SignatureScheme::ECDSA_NISTP256_SHA256 must only validate signatures using public keys on the right curve – rustls does not enforce this requirement for you.

This trait method has a default implementation that uses webpki to verify the signature.

Return the list of SignatureSchemes that this verifier will handle, in verify_tls12_signature and verify_tls13_signature calls.

This should be in priority order, with the most preferred first.

This trait mehod has a default implementation that reflects the schemes supported by webpki.
