# CO₂: Human ciphers, implemented in Rust.

CO₂ (a.k.a. "Cipherium Dioxide", or perhaps "Cipher Dioxide", or just "C-O-2" if you insist) is an extensible Rust library for "human ciphers" (which are simpler ciphers, such as the Caesar cipher or Vigenère cipher).

## Example (proposed API)

```rs

use co2::prelude::*;

use subst::VigenereBuilder;

fn main() {

    // Build the cipher encoder/decoder for a standard Vigenère cipher

    // with the key `ciphersarecool`. Everything else should be set to

    // the default.

    let c = VigenereBuilder::standard().key("ciphersarecool").build();

    // Encode "Hello, world!" using the Vigenère cipher with the

    // previously set key. This returns a `String`, so to compare

    // it with a `&str`, it needs some coaxing.

    assert_eq!(&c.encode("Hello, world!"), "Jmass, ngrch!");

    // Decode some encoded text with the previously set key.

    // This returns a `String` too.

    assert_eq!(&c.decode("Kb lvvbk!"), "It works!");

}

```
