CryptLib

A Java library for encrypting and decrypting text with AES

WARNING!

Please be sure you know what you are doing!
This is a 128 bit AES/ECB cipher! Not a military encryption!
You should only encrypt text!

Usage

Create an object

CryptLib cipher = new CryptLib();

Printout encrypted string

System.out.println(">" + cipher.encrypt("Test", "Test1234Test1234") + "<");

Printout decrypted string

System.out.println(">" + cipher.decrypt("5c61eZ2k+CbeDThLD2bP/w==", "Test1234Test1234") + "<");

Output:

>5c61eZ2k+CbeDThLD2bP/w==<

>Test<

Or try out the PermKey function:

Create an object

CryptLib cipher = new CryptLib("Test1234Test1234");

Printout encrypted string

System.out.println(">" + cipher.encrypt("Test") + "<");

Printout decrypted string

System.out.println(">" + cipher.decrypt("5c61eZ2k+CbeDThLD2bP/w==") + "<");

Output:

>5c61eZ2k+CbeDThLD2bP/w==<

>Test<
