Java provides KeyGenerator class this class is used to generate secret keys and objects of this class are reusable. To generate keys using the KeyGenerator class follow the steps given below. Step 1: Create a KeyGenerator object. The KeyGenerator class provides getInstance method which accepts a String variable representing the required key-generating algorithm and returns a KeyGenerator. Jul 06, 2016  Given a message, We would like to encrypt & decrypt plain/cipher text using AES CBC algorithm in java. We will perform following operations: Generate symmetric key using AES-128.; Generate initialization vector used for CBC (Cipher Block Chaining).; Encrypt message using symmetric key and initialization vector.; Decrypt the encrypted message using symmetric key and initialization. AES is block cipher capable of handling 128 bit blocks, using keys sized at 128, 192, and 256 bits. Each cipher encrypts and decrypts data in blocks of 128 bits using cryptographic keys of 128-, 192- and 256-bits, respectively. It uses the same key for encrypting and decrypting. The Java KeyGenerator class (javax.crypto.KeyGenerator) is used to generate symmetric encryption keys.A symmetric encryption key is a key that is used for both encryption and decryption of data, by a symmetric encryption algorithm.

Secret Key Skin Care

Java provides KeyGeneratorWindows xp service pack 2 product key generator and activator. class this class is used to generate secret keys and objects of this class are reusable.

To generate keys using the KeyGenerator class follow the steps given below.

Generate 128-bit Aes Secret Key In Java Version

Step 1: Create a KeyGenerator object

The KeyGenerator class provides getInstance() method which accepts a String variable representing the required key-generating algorithm and returns a KeyGenerator object that generates secret keys.

Create KeyGenerator object using the getInstance() method as shown below.

Step 2: Create SecureRandom object

The SecureRandom class of the java.Security package provides a strong random number generator which is used to generate random numbers in Java. Instantiate this class as shown below.

Step 3: Initialize the KeyGenerator

The KeyGenerator class provides a method named init() this method accepts the SecureRandom object and initializes the current KeyGenerator.

Initialize the KeyGenerator object created in the previous step using the init() method.

Example

Following example demonstrates the key generation of the secret key using the KeyGenerator class of the javax.crypto package.

Output

The above program generates the following output −
