Question

How to encode and decode a string to base64 in Rust

Answer 1

use base64::{engine::general_purpose::STANDARD, Engine as _};
use std::str;

fn base64_encode(input: &str) -> String {
    STANDARD.encode(input.as_bytes())
}

fn base64_decode(encoded: &str) -> String {
    let bytes = STANDARD.decode(encoded).expect("Failed to decode Base64");

    str::from_utf8(&bytes).expect("Invalid UTF-8").to_string()
}

fn main() {
    let encoded = base64_encode("rust programming");
    println!("{}", encoded);

    let decoded = base64_decode(&encoded);
    println!("{}", decoded);
}
