Java DES Encrypt/Decrypt methods

Question

I need to create two simple methods for string DES encryption/decruption. The goal is to have these two methods in the following form

public static String desEcnrypt(String key, String clearMessage) { ..... }

public static String desDecrypt(String key, String encryptedMessage) { ..... }

I haven't found yet any example in this form.

Answer 1

Use the "not-yet-commons-ssl.jar" from http://juliusdavies.ca/commons-ssl/.

http://juliusdavies.ca/commons-ssl/pbe.html

PBE code example (DES-3):*

char[] password = {'c','h','a','n','g','e','i','t'};
byte[] data = "Hello World!".getBytes();

// Encrypt!
byte[] encrypted = OpenSSL.encrypt("des3", password, data);
System.out.println("ENCRYPTED: [" + new String(encrypted) + "]");

// Decrypt results of previous!
data = OpenSSL.decrypt("des3", password, encrypted);
System.out.println("DECRYPTED: [" + new String(data) + "]");


OUTPUT:
=======================
ENCRYPTED: [U2FsdGVkX19qplb9qVDVVEYxH8wjJDGpMS+F4/2pS2c=]
DECRYPTED: [Hello World!]
