Class Blowfish

java.lang.Object
  goldengate.common.crypto.KeyObject
      goldengate.common.crypto.Blowfish

public class Blowfish
extends KeyObject

This class handles methods to crypt and decrypt messages with Blowfish (efficient: 4000/s both at 56 and 128 keysize).

Usage:

• Create a Blowfish object: Blowfish key = new Blowfish();
• 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);
