java.lang.Object

org.waarp.common.crypto.KeyObject

org.waarp.common.crypto.Des

public class Des
extends KeyObject

This class handles methods to crypt and decrypt messages with DES algorithm (very efficient: 40000/s).

Usage:

• Create a Des object: Des key = new Des();
• Create a key:
  • Generate: key.generateKey();
    The method key.getSecretKeyInBytes() allow getting the key in Bytes.
  • From an external source: key.setSecretKey(arrayOfBytes);
• To crypt a String in a Base64 format: String myStringCrypt = key.cryptToString(myString);
• To decrypt one string from Base64 format to the original String: String myStringDecrypt = key.decryptStringInString(myStringCrypte);
