How to use

extension ViewController: UITextFieldDelegate{
  func textFieldDidBeginEditing(_ textField: UITextField) {
    _ = textField.resignFirstResponder()
    let vc = IKCryptoKeyBoardViewController()
    vc.delegate = self
    self.present(vc, animated: true)
  }
}
extension ViewController: IKCryptoKeyBoardViewControllerDelegate {
  // get encrypted data from IKCryptoKeyBoardViewController
  func didEncrypted(plain: String, encryptedData: Array<UInt8>) {
    // `plain` is replaced password as "aaaaa..."
    // `encryptedData` is encrypted password
  }
  // for debug
  func didDecrypted(decryptedData: Array<UInt8>) {
  // `decryptedData` is password
  }
}

Customize

The Rules.

If you keep the rules, you can use all of the languages keyboard.

var configure = IKCryptoKeyBoardConfigure()
vc.configure = configure

Custom Example

• Deutsch Crypto Keyboard
  ``` swift
  configure.isUseSubKeys = false
  configure.informationText = “This is Deutsch Crypto Keyboard”
  configure.mainQwerty.firstLine = “qwertzuiopü”
  configure.mainQwerty.secondLine = “asdfghjklöä”
  configure.mainQwerty.thirdLine = “yxcvbnm”

configure.shiftMainQwerty.firstLine = “QWERTZUIOPÜ”
configure.shiftMainQwerty.secondLine = “ASDFGHJKLÖÄ”
configure.shiftMainQwerty.thirdLine = “YXCVBNM”

configure.color.defaultKeyBackground = UIColor(red:0.83, green:0.72, blue:0.21, alpha:1.0)
configure.color.touchedKeyBackground = .gray
configure.color.functionKeyBackground = UIColor(red:0.70, green:0.08, blue:0.08, alpha:1.0)
configure.color.keyboardBackground = UIColor(red:0.17, green:0.14, blue:0.14, alpha:1.0)
configure.color.functionKeyText = .black
configure.color.defaultKeyText = .black
configure.color.background = .white

<img src="/Screenshots/Deutsch.png" />
- Ressian Crypto Keyboard
``` swift
configure.isUseSubKeys = false
configure.informationText = "This is Ressian Crypto Keyboard"
configure.mainQwerty.firstLine = "йцукенгшщзх"
configure.mainQwerty.secondLine = "фывапролджэ"
configure.mainQwerty.thirdLine = "ячсмитьбю"
configure.shiftMainQwerty.firstLine = "ЙЦУКЕНГШЩЗХ"
configure.shiftMainQwerty.secondLine = "ФЫВАПРОЛДЖЭ"
configure.shiftMainQwerty.thirdLine = "ЯЧСМИТЬБЮ"
configure.color.defaultKeyBackground = UIColor(red:0.13, green:0.33, blue:0.99, alpha:1.0)
configure.color.touchedKeyBackground = .gray
configure.color.keyboardBackground = UIColor(red:0.99, green:0.99, blue:0.99, alpha:1.0)
configure.color.functionKeyBackground = UIColor(red:0.83, green:0.27, blue:0.27, alpha:1.0)
configure.color.functionKeyText = .white
configure.color.defaultKeyText = .white
configure.color.background = .white

Use Custom Cipher

if you want custom cipher encrypt & decrypt,

let vc = IKCryptoKeyBoardViewController()
var configure = IKCryptoKeyBoardConfigure()
vc.configure.cipher.type = .custom // default is aes
vc.configure = configure
extension ViewController: IKCryptoKeyBoardViewControllerDelegate {
  func doEncrypt(plain: String) -> Array<UInt8> {
    // describe encrypt function
  }
  // for debug
  func doDecrypt(encrypted: Array<UInt8>) -> Array<UInt8> {
    // describe decrypt function
  }
}
