Struct physis::blowfish::Blowfish

pub struct Blowfish { /* private fields */ }

Implementation of the Blowfish block cipher, specialized for encrypting and decrypting SqexArg - the technique used to encrypt game arguments by the launcher.

Example

let key = b"abcdefgh";
let data = b"foobar  ";

let fish = Blowfish::new(key);
let encrypted = fish.encrypt(data).unwrap();
let decrypted = fish.decrypt(&encrypted).unwrap();

Implementations

impl Blowfish

pub fn new(key: &[u8]) -> Blowfish

Initializes a new Blowfish session with a key.

pub fn encrypt(&self, data: &[u8]) -> Option<Vec<u8>>

Encrypts a block of data. If the encryption for any reason fails, returns None.

pub fn decrypt(&self, data: &[u8]) -> Option<Vec<u8>>

Decrypts a block of data. If the decryption fails due to buffer overflow issues, will return None - but this does not indicate that the wrong key was used.
