Struct actix_tls::rustls::ServerConfig

pub struct ServerConfig {
    pub ciphersuites: Vec<&'static SupportedCipherSuite, Global>,
    pub ignore_client_order: bool,
    pub mtu: Option<usize>,
    pub session_storage: Arc<dyn StoresServerSessions + Send + Sync + 'static>,
    pub ticketer: Arc<dyn ProducesTickets + 'static>,

    pub versions: Vec<ProtocolVersion, Global>,
    pub key_log: Arc<dyn KeyLog + 'static>,
    // some fields omitted
}

Common configuration for a set of server sessions.

Making one of these can be expensive, and should be once per process rather than once per connection.

Fields

ciphersuites: Vec<&'static SupportedCipherSuite, Global>

List of ciphersuites, in preference order.

ignore_client_order: bool

Ignore the client’s ciphersuite order. Instead, choose the top ciphersuite in the server list which is supported by the client.

mtu: Option<usize>

Our MTU. If None, we don’t limit TLS message sizes.

session_storage: Arc<dyn StoresServerSessions + Send + Sync + 'static>

How to store client sessions.

ticketer: Arc<dyn ProducesTickets + 'static>

How to produce tickets.

cert_resolver: Arc<dyn ResolvesServerCert + 'static>

How to choose a server cert and key.

alpn_protocols: Vec<Vec<u8, Global>, Global>

Protocol names we support, most preferred first. If empty we don’t do ALPN at all.

versions: Vec<ProtocolVersion, Global>

Supported protocol versions, in no particular order. The default is all supported versions.

key_log: Arc<dyn KeyLog + 'static>

How to output key material for debugging. The default does nothing.

Implementations

impl ServerConfig

pub fn new(
    client_cert_verifier: Arc<dyn ClientCertVerifier + 'static>
) -> ServerConfig

Make a ServerConfig with a default set of ciphersuites, no keys/certificates, and no ALPN protocols. Session resumption is enabled by storing up to 256 recent sessions in memory. Tickets are disabled.

Publicly-available web servers on the internet generally don’t do client authentication; for this use case, client_cert_verifier should be a NoClientAuth. Otherwise, use AllowAnyAuthenticatedClient or another implementation to enforce client authentication.

We don’t provide a default for client_cert_verifier because the safest default, requiring client authentication, requires additional configuration that we cannot provide reasonable defaults for.

pub fn with_ciphersuites(
    client_cert_verifier: Arc<dyn ClientCertVerifier + 'static>,
    ciphersuites: &[&'static SupportedCipherSuite]
) -> ServerConfig

Make a ServerConfig with a custom set of ciphersuites, no keys/certificates, and no ALPN protocols. Session resumption is enabled by storing up to 256 recent sessions in memory. Tickets are disabled.

Publicly-available web servers on the internet generally don’t do client authentication; for this use case, client_cert_verifier should be a NoClientAuth. Otherwise, use AllowAnyAuthenticatedClient or another implementation to enforce client authentication.

We don’t provide a default for client_cert_verifier because the safest default, requiring client authentication, requires additional configuration that we cannot provide reasonable defaults for.

pub fn set_persistence(
    &mut self,
    persist: Arc<dyn StoresServerSessions + Send + Sync + 'static>
)

Sets the session persistence layer to persist.

pub fn set_single_cert(
    &mut self,
    cert_chain: Vec<Certificate, Global>,
    key_der: PrivateKey
) -> Result<(), TLSError>

Sets a single certificate chain and matching private key. This certificate and key is used for all subsequent connections, irrespective of things like SNI hostname.

Note that the end-entity certificate must have the Subject Alternative Name extension to describe, e.g., the valid DNS name. The commonName field is disregarded.

cert_chain is a vector of DER-encoded certificates. key_der is a DER-encoded RSA, ECDSA, or Ed25519 private key.

This function fails if key_der is invalid.

pub fn set_single_cert_with_ocsp_and_sct(
    &mut self,
    cert_chain: Vec<Certificate, Global>,
    key_der: PrivateKey,
    ocsp: Vec<u8, Global>,
    scts: Vec<u8, Global>
) -> Result<(), TLSError>

Sets a single certificate chain, matching private key and OCSP response. This certificate and key is used for all subsequent connections, irrespective of things like SNI hostname.

cert_chain is a vector of DER-encoded certificates. key_der is a DER-encoded RSA, ECDSA, or Ed25519 private key. ocsp is a DER-encoded OCSP response. Ignored if zero length. scts is an SignedCertificateTimestampList encoding (see RFC6962) and is ignored if empty.

This function fails if key_der is invalid.

pub fn set_protocols(&mut self, protocols: &[Vec<u8, Global>])

Set the ALPN protocol list to the given protocol names. Overwrites any existing configured protocols.

The first element in the protocols list is the most preferred, the last is the least preferred.

pub fn set_client_certificate_verifier(
    &mut self,
    verifier: Arc<dyn ClientCertVerifier + 'static>
)

Overrides the default ClientCertVerifier with something else.

Trait Implementations

impl Clone for ServerConfig

pub fn clone(&self) -> ServerConfig

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
