AES (Block Cipher)

import 'package:encrypt/encrypt.dart';

void main() {
  final key = 'my32lengthsupersecretnooneknows1';

  final encrypter = new Encrypter(new AES(key));
  final plainText = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit ........';

  final encryptedText = encrypter.encrypt(plainText);
  final decryptedText = encrypter.decrypt(encryptedText);

  print(encryptedText); // db066ce180f62f020617eb720b891c1efcc48b217cb83272812a8efe3b30e7eae4373ddcede4ea77bdae77d126d95457b3759b1983bf4cb4a6a5b051a5690bdf
  print(decryptedText); // Lorem ipsum dolor sit amet, consectetur adipiscing elit ........
}

Salsa20 (Stream Cipher)

import 'package:encrypt/encrypt.dart';

void main() {
  final key = 'private!!!!!!!!!';
  final iv = '8bytesiv'; // https://en.wikipedia.org/wiki/Initialization_vector
  final plainText = 'Secret';

  final encrypter = new Encrypter(new Salsa20(key, iv));

  final encrypted = encrypter.encrypt(plainText);
  final decrypted = encrypter.decrypt(encrypted);

  print(encrypted); // c5cc91943cf0
  print(decrypted); // Secret
}

Salsa20 With Chinese

import 'package:encrypt/encrypt.dart';

void main() {
  final key = '1234567890123456';
  final iv = '8bytesiv';
  final encryptor = Encrypter(Salsa20(key, iv));
  String text = '你好';
  String base64Text = base64.encode(utf8.encode(text));
  String encText  = encryptor.encrypt(base64Text);
  var decStr = utf8.decode(base64.decode(encryptor.decrypt(encText)));

  print('origin:'+text);//你好
  print('base64Text:'+base64Text);//5L2g5aW9
  print('enc text:'+encText);//c72f29fd34b15145
  print('dec text:'+decStr);//你好
}
