Expand description

A TLS 1.2 cipher suite supported by rustls.

Fields§

§common: CipherSuiteCommon

Common cipher suite fields.

§kx: KeyExchangeAlgorithm

How to exchange/agree keys.

§sign: &'static [SignatureScheme]

How to sign messages for authentication.

§fixed_iv_len: usize

How long the fixed part of the ‘IV’ is.

This isn’t usually an IV, but we continue the terminology misuse to match the standard.

§explicit_nonce_len: usize

This is a non-standard extension which extends the key block to provide an initial explicit nonce offset, in a deterministic and safe way. GCM needs this, chacha20poly1305 works this way by design.

Implementations§

source§

impl Tls12CipherSuite

source

pub fn resolve_sig_schemes( &self, offered: &[SignatureScheme] ) -> Vec<SignatureScheme>

Resolve the set of supported SignatureSchemes from the offered SupportedSignatureSchemes. If we return an empty set, the handshake terminates.

source

pub fn hash_algorithm(&self) -> &'static Algorithm

Which hash function to use with this suite.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
