This example is showing you how to use the Jasypt API to write a simple code to do string encryption and decryption. In this example we are going to use the BasicTextEncryptor class which use the PBEWithMD5AndDES algorithm. This class is an implementation of the TextEncryoptor interface.

You can download the library from their website, it’s already included with the dependency libraries required by Jasypt such as the commons-codec and commons-lang.

package org.kodejava.jasypt;

import org.jasypt.util.text.BasicTextEncryptor;

public class TextEncryptorDemo {
    public static void main(String[] args) {
        String text = "The quick brown fox jumps over the lazy dog";
        System.out.println("Text      = " + text);

        BasicTextEncryptor bte = new BasicTextEncryptor();
        bte.setPassword("HelloWorld");

        String encrypted = bte.encrypt(text);
        System.out.println("Encrypted = " + encrypted);

        String original = bte.decrypt(encrypted);
        System.out.println("Original  = " + original);
    }
}

The result produced by the code above:

Text      = The quick brown fox jumps over the lazy dog
Encrypted = kYXn3rL/YChh9EraGYh3cyuRxLo+dKocd+W33yW53TfgQecTpLRcIt5AH974d0YFDcFFXUTfNAk=
Original  = The quick brown fox jumps over the lazy dog
