This is a Swift implementation of the Extended Tiny Encryption Algorithm (XTEA).
import XTEAUse the XTEA functions to encipher/decipher data.
let key = XTEA.Key(k0: 0xf5ff9b28, k1: 0xdc32c866, k2: 0xe65d0706, k3: 0xf6a2189c)
let plainText = XTEA.Data(v0: 0x646d1ff0, v1: 0x4ff2dd13)
let encrypted = XTEA.encipher(data: plainText, key: key)
...
val decrypted = XTEA.decipher(data: cipherText, key: key)Optionally, you can specify the number of XTEA rounds to perform (default: 32, the recommended number) using the rounds parameter:
let encrypted = XTEA.encipher(data: plainText, key: key, rounds: 36)
val decrypted = XTEA.decipher(data: cipherText, key: key, rounds: 36)
