Struct web3_async_native_tls::TlsConnector

pub struct TlsConnector { /* fields omitted */ }

Connect a client to a remote server.

Examples

use async_std::prelude::*;
use async_std::net::TcpStream;
use async_native_tls::TlsConnector;

let stream = TcpStream::connect("google.com:443").await?;
let mut stream = TlsConnector::new()
    .use_sni(true)
    .connect("google.com", stream)
    .await?;
stream.write_all(b"GET / HTTP/1.0\r\n\r\n").await?;

let mut res = Vec::new();
stream.read_to_end(&mut res).await?;
println!("{}", String::from_utf8_lossy(&res));

Implementations

impl TlsConnector

pub fn new() -> Self

Create a new instance.

pub fn identity(self, identity: Identity) -> Self

Sets the identity to be used for client certificate authentication.

pub fn min_protocol_version(self, protocol: Option<Protocol>) -> Self

Sets the minimum supported protocol version.

A value of None enables support for the oldest protocols supported by the implementation. Defaults to Some(Protocol::Tlsv10).

pub fn max_protocol_version(self, protocol: Option<Protocol>) -> Self

Sets the maximum supported protocol version.

A value of None enables support for the newest protocols supported by the implementation. Defaults to None.

pub fn add_root_certificate(self, cert: Certificate) -> Self

Adds a certificate to the set of roots that the connector will trust.

The connector will use the system’s trust root by default. This method can be used to add to that set when communicating with servers not trusted by the system. Defaults to an empty set.

pub fn danger_accept_invalid_certs(self, accept_invalid_certs: bool) -> Self

Controls the use of certificate validation.

Defaults to false.

Warning

You should think very carefully before using this method. If invalid certificates are trusted, any certificate for any site will be trusted for use. This includes expired certificates. This introduces significant vulnerabilities, and should only be used as a last resort.

pub fn use_sni(self, use_sni: bool) -> Self

Controls the use of Server Name Indication (SNI).

Defaults to true.

pub fn danger_accept_invalid_hostnames(
    self,
    accept_invalid_hostnames: bool
) -> Self

Controls the use of hostname verification.

Defaults to false.

Warning

You should think very carefully before using this method. If invalid hostnames are trusted, any valid certificate for any site will be trusted for use. This introduces significant vulnerabilities, and should only be used as a last resort.

pub async fn connect<S>(
    &self,
    host: impl Into<Host>,
    stream: S
) -> Result<TlsStream<S>> where
    S: AsyncRead + AsyncWrite + Unpin, 

Connect to a remote server.

Examples

use async_std::prelude::*;
use async_std::net::TcpStream;
use async_native_tls::TlsConnector;

let stream = TcpStream::connect("google.com:443").await?;
let mut stream = TlsConnector::new()
    .use_sni(true)
    .connect("google.com", stream)
    .await?;
stream.write_all(b"GET / HTTP/1.0\r\n\r\n").await?;

let mut res = Vec::new();
stream.read_to_end(&mut res).await?;
println!("{}", String::from_utf8_lossy(&res));
