I had tried to do AES256 encryption in Swift3, by using many libraries like CryptoSwift, but couldnt get proper result.
let aes = try AES(key: anykey, iv: "") let ciphertext = try aes.encrypt(data) The mode I want to try is as below.
Algorithm: Rijndael-256 MODE: ECB IV: NULL if there is mistake in my code, or any better way to AES256 encrypt in Swift3, answer me please.
RNCryptor is a useful framework for AES256 encryption and decryption.
// Encryption let data ... // Some data you want to encrypt let password = "0Bfy8q9475jgjjbsu" let ciphertext = RNCryptor.encryptData(data, password: password) // Decryption do { let originalData = try RNCryptor.decryptData(ciphertext, password: password) } catch let error { print("Can not Decrypt With Error: \n\(error)\n") } 
You could also try the CommonCrypto C library which RNCryptor wraps. This comes as standard with XCode. Unfortunately it doesn't have a swift framework setup for it. This project creates a framework for easy use in swift https://github.com/sergejp/CommonCrypto/tree/master/CommonCrypto
You can find example code using the CommonCrypto library here https://github.com/adam-fowler/swift-library/blob/master/data/aes.swift.
