Jasypt

One more little library that I’ve come to love: jasypt. It’s a simplified veneer over the top of the gargantuan java security apparatus. All I wanted to do was encrypt a String before putting it in a Cookie.

  BasicTextEncryptor encryptor = new BasicTextEncryptor();
  encryptor.setPassword(key);
  String cipherText = encryptor.encrypt(clearText);

It nicely base64 encodes the result, which is ideal for Cookie stuffing.

The reverse operation is just as simple.

  BasicTextEncryptor encryptor = new BasicTextEncryptor();
  encryptor.setPassword(key);
  String recoveredText = encryptor.decrypt(cipherText);
