How to Use TLS Certificates in Rust

Use the rustls-tls feature in your reqwest dependency to enable TLS with the rustls crate, which is the standard TLS implementation for Rust. Add the following to your Cargo.toml to configure the client to use TLS securely:

[dependencies]
reqwest = { version = "0.12", default-features = false, features = ["rustls-tls"] }

This setup allows your Rust application to make HTTPS requests using rustls without requiring OpenSSL.

TLS certificates secure your internet connections so data can't be read by others. In Rust, you enable this by adding a specific setting to your project file that tells the system to use a built-in security tool called rustls. It's like turning on a lock on your door before you leave the house.
