How do I encrypt or decrypt bytes information using StandardPBEByteEncryptor?

By Wayan in Jasypt 0 Comment

This code demonstrate how to use the StandardPBEByteEncryptor class to encrypt and decrypt bytes information.

package org.kodejava.jasypt;

import org.jasypt.encryption.pbe.StandardPBEByteEncryptor;

import java.util.Arrays;

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

        StandardPBEByteEncryptor encryptor = new StandardPBEByteEncryptor();
        encryptor.setAlgorithm("PBEWithMD5AndDES");
        encryptor.setPassword("HelloWorld");

        byte[] encrypted = encryptor.encrypt(text.getBytes());
        System.out.println("Encrypted = " + Arrays.toString(encrypted));

        byte[] original = encryptor.decrypt(encrypted);
        System.out.println("Original  = " + Arrays.toString(original));
    }
}

The results of our code are:

Text      = [84, 104, 101, 32, 113, 117, 105, 99, 107, 32, 98, 114, 111, 119, 110, 32, 102, 111, 120, 32, 106, 117, 109, 112, 115, 32, 111, 118, 101, 114, 32, 116, 104, 101, 32, 108, 97, 122, 121, 32, 100, 111, 103]
Encrypted = [64, -99, -51, -21, -2, -6, -1, 76, -46, 87, 119, 62, -83, -74, 30, -90, 0, -97, 92, 0, 116, 32, -97, 67, -121, 57, -116, -11, 52, -73, 0, -104, -85, -109, -28, 106, 100, -76, -75, 55, -12, 49, 16, 65, -37, 88, 78, -68, 39, 14, 96, -22, 56, 63, -26, 18]
Original  = [84, 104, 101, 32, 113, 117, 105, 99, 107, 32, 98, 114, 111, 119, 110, 32, 102, 111, 120, 32, 106, 117, 109, 112, 115, 32, 111, 118, 101, 114, 32, 116, 104, 101, 32, 108, 97, 122, 121, 32, 100, 111, 103]
