certstream-rs

An unofficial port of certstream-go to Rust.

This library streams Certificate Transparency Log notifications from https://certstream.calidog.io/ (or a custom instance of the certstream-server).

This was done as a small project to learn Rust. All comments/criticism/pull requests welcome -- the code quality is likely terrible.

Example

```

git clone https://github.com/Andoryuuta/certstream-rs cd certstream-rs cargo run --example watch_hostnames ```

Usage

```rust use certstreamrs::CertstreamClient; use futuresutil::{pinmut, StreamExt};

[tokio::main]

async fn main() { // Create the client and open the connection/stream. let client = CertstreamClient::default(); let stream = client.watchcerts(); pinmut!(stream);

// Read from the stream and print the certificate message.
loop {
    let msg = stream.next().await.unwrap().unwrap();

    println!(
        "Source: {} | First Hostname: {}",
        msg.data.source.name,
        msg.data.leaf_cert.all_domains.first().unwrap()
    );
}

} ```
