hello fellow programmers,
It's about ios(Swift3) encrypt/decrypt: I'm an ios swift beginner. I followed a tutorial at https://www.funboxpower.com/php_android_ios_aes to complete encrypt/decrypt between Android and PHP.
Now I wanna to do the same on iOS(Swift3), the author mentioned ios(object-c) method as this Wanted Compatible AES code Encrypt/Decrypt for Iphone, Android, Windows/XP
so I find CryptoSwift and it help me to encrypt my string. but the result is not same as Android and PHP. How can I do that use iOS(Swift3) with CryptoSwift to encrypt/decrypt like the tutorial(Android/PHP) ?
Here is the code for encryption on Swift:
import CryptoSwift
class LoginViewController: UIViewController {
@IBAction func loginAction(sender: AnyObject) {
let account = self.accountTextField.text
let password = self.passwordTextField.text
let key = "itakeylengthtotalis32keykeykey00"
let iv = "0000000000000000"
let encryptedAccount = try! account?.aesEncrypt(key:key, iv: iv)
let encryptedPassword = try! password?.aesEncrypt(key:key, iv: iv)
//result here ------------------------------
print( "encryptedAccount: " + encryptedAccount! )
print( "encryptedPassword: " + encryptedPassword! )
}
}
extension String {
func aesEncrypt(key: String, iv: String) -> String? {
var result: String?
do {
// 用UTF8的编碼方式將字串轉成Data / use Data func for a UT8 string
let data: Data = self.data(using: String.Encoding.utf8, allowLossyConversion: true)!
// 用AES的方式將Data加密 / use AES to encrypt Data
let aecEnc: AES = try AES(key: key, iv: iv, blockMode: .CBC, padding:PKCS7())
let enc = try aecEnc.encrypt(data.bytes)
// 使用Base64編碼方式將Data轉回字串 / use Base64 to encode string
let encData: Data = Data(bytes: enc, count: enc.count)
result = encData.base64EncodedString()
} catch {
print("\(error.localizedDescription)")
}
return result
}
