pkce-rs

A very simple library for generating code verifiers and challenges to use for OAuth Proof Key for Code Exchange. It is not rocket science.

extern crate pkce;
 
fn main() {
    // Generate a random 128-byte code verifier (must be between 43 and 128 bytes)
    let code_verify = pkce::code_verifier(128);
    // Generate an encrypted code challenge accordingly
    let code_challenge = pkce::code_challenge(&code_verify);

    println!("Code challenge generated: {}", code_challenge);
}

Wow, it really is that simple.
