Swift implementation of RC4. Usage: let data: NSData // the NSData to crypt let key: String // the key to crypt let encodedData = RC4.crypt(data, key) Or streaming encryption: let key: String let cryptor = RC4(key: key) while true { let data = ... // fetch data let encodedData = cryptor.crypt(data) // handles encodedData // break on finish loading }
