- The Java KeyPairGenerator class (java.security.KeyPairGenerator) is used to generate asymmetric encryption / decryption key pairs. An asymmetric key pair consists of two keys. The first key is typically used to encrypt data. The second key which is used to decrypt data encrypted with the first key. Public Key, Private Key Type Key Pairs.
- 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.
- Java Code Examples for javax.crypto.KeyGenerator. The following are top voted examples for showing how to use javax.crypto.KeyGenerator. These examples are extracted from open source projects. You can vote up the examples you like and your votes will be used in our system to generate more good examples.
- What is the recommended way of generating a secure, random AES key in Java, using the standard JDK? In other posts, I have found this, but using a SecretKeyFactory might be a better idea: KeyGene.
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. In this Java KeyGenerator tutorial I will show you how to generate symmetric encryption keys.
Download Java License Generator for free. Jicense is a license generator for the products or projects developed using Java language. You could customize your license generator set by implementing the jicense core api or make use of one of the existing demo sources.
Creating a KeyGenerator Instance
Before you can use the Java KeyGenerator class you must create a KeyGenerator instance. You create a KeyGenerator instance by calling the static method getInstance() passing as parameter the name of the encryption algorithm to create a key for. Here is an example of creating a Java KeyGenerator instance:

This example creates a KeyGenerator instance which can generate keys for the AES encryption algorithm.
Initializing the KeyGenerator
After creating the KeyGenerator instance you must initialize it. Initializing a KeyGenerator instance is done by calling its init() method. Here is an example of initializing a KeyGenerator instance:
Openssl generate certificate from key. The KeyGeneratorinit() method takes two parameters: The bit size of the keys to generate, and a SecureRandom that is used during key generation.
