No Chat Reports (NCR) Chat Encryption

This crate implements the No Chat Reports's custom chat encryption. More specifically this implements a fork of No Chat Reports.

All functionalities of the custom chat encryption are implemented. You can still use this crate normally if you are using the original No Chat Reports.

• Caesar, Ecb, Cfb8 and Gcm encryption
• Base64 (old), Base64r, Sus16 and Mc256 encoding
• Passphrase

Examples

Encrypting

use ncr::{
    encoding::Base64rEncoding,
    encryption::{Cfb8Encryption, Encryption},
    utils::prepend_header,
    AesKey,
};

fn main() {
    let key = AesKey::gen_from_passphrase(b"secret");

    let plaintext = prepend_header("I love Minecraft!");
    let ciphertext = Cfb8Encryption(Base64rEncoding).encrypt(&plaintext, &key).unwrap();

    println!("{}", ciphertext);
}

Decrypting

use ncr::{
    encoding::Base64rEncoding,
    encryption::{Cfb8Encryption, Encryption},
    utils::trim_header,
    AesKey,
};

fn main() {
    let key = AesKey::gen_from_passphrase(b"secret");

    let ciphertext = r#"%[2_0»³"!7).«?;!.$¥`¶:8~667ª¸[¬)¢+¤^"#;
    let plaintext = Cfb8Encryption(Base64rEncoding).decrypt(ciphertext, &key).unwrap();

    let plaintext = trim_header(&plaintext).unwrap();

    assert_eq!(plaintext, "I love Minecraft!");
}
