ClientHello

rama::tls::rustls::types::client

Struct ClientHello

pub struct ClientHello { /* private fields */ }

Available on crate feature rustls only.

Expand description

When a client first connects to a server, it is required to send the ClientHello as its first message.

The ClientHello contains random data, cipher suites, legacy content from <= TLS.12 and extensions.

For Rama however we only focus on the parts which a user might want to inspect and/or set.

Implementations§

impl ClientHello

pub fn new( protocol_version: ProtocolVersion, cipher_suites: Vec<CipherSuite>, compression_algorithms: Vec<CompressionAlgorithm>, extensions: Vec<ClientHelloExtension>, ) -> ClientHello

Available on crate feature boring only.

pub fn protocol_version(&self) -> ProtocolVersion

Available on crate feature boring only.

Return all ProtocolVersions defined in this ClientHello.

pub fn cipher_suites(&self) -> &[CipherSuite]

Available on crate feature boring only.

Return all CipherSuites defined in this ClientHello.

Return all ClientHelloExtensions defined in this ClientHello.

pub fn ext_server_name(&self) -> Option<&Domain>

Available on crate feature boring only.

Return the server name (SNI) if it is set in the ClientHelloExtension defined in this ClientHello.

See ClientHelloExtension::ServerName for more information about the server name.

pub fn ext_supported_groups(&self) -> Option<&[SupportedGroup]>

Available on crate feature boring only.

Return the elliptic curves supported by this client if it is set in the ClientHelloExtension defined in this ClientHello.

See ClientHelloExtension::SupportedGroups for more information about these curves.

pub fn ext_ec_point_formats(&self) -> Option<&[ECPointFormat]>

Available on crate feature boring only.

Return the EC point formats supported by this client if it is set in the ClientHelloExtension defined in this ClientHello.

See ClientHelloExtension::ECPointFormats for more information about this.

pub fn ext_signature_algorithms(&self) -> Option<&[SignatureScheme]>

Available on crate feature boring only.

See ClientHelloExtension::SignatureAlgorithms for more information about these algorithms

pub fn ext_alpn(&self) -> Option<&[ApplicationProtocol]>

Available on crate feature boring only.

Return the application layer protocols supported for negotiation by this client if it is set in the ClientHelloExtension defined in this ClientHello.

See ClientHelloExtension::ApplicationLayerProtocolNegotiation for more information about these protocols (ALPN).

pub fn ext_alps(&self) -> Option<&[ApplicationProtocol]>

Available on crate feature boring only.

Return the application layer protocols for which alps is supported if it is set in the ClientHelloExtension defined in this ClientHello.

See ClientHelloExtension::ApplicationSettings for more information about these protocols (ALPS).

pub fn supported_versions(&self) -> Option<&[ProtocolVersion]>

pub fn has_encrypted_client_hello(&self) -> bool

Available on crate feature boring only.

Return true when this ClientHello carries an EncryptedClientHello extension. Useful for triage: trailing trailer-content parse warnings often correlate with ECH-using clients (e.g. recent Firefox builds), and a structured ech field on the parse log lets operators grep ech=true rather than infer.
