This class provides the functionality of a secret (symmetric) key generator.

Key generators are constructed using one of the getInstance class methods of this class.

KeyGenerator objects are reusable, i.e., after a key has been generated, the same KeyGenerator object can be re-used to generate further keys.

There are two ways to generate a key: in an algorithm-independent manner, and in an algorithm-specific manner. The only difference between the two is the initialization of the object:

• Algorithm-Independent Initialization

  All key generators share the concepts of a keysize and a source of randomness. There is an init method in this KeyGenerator class that takes these two universally shared types of arguments. There is also one that takes just a keysize argument, and uses the SecureRandom implementation of the highest-priority installed provider as the source of randomness (or a system-provided source of randomness if none of the installed providers supply a SecureRandom implementation), and one that takes just a source of randomness.

  Since no other parameters are specified when you call the above algorithm-independent init methods, it is up to the provider what to do about the algorithm-specific parameters (if any) to be associated with each of the keys.

• Algorithm-Specific Initialization

  For situations where a set of algorithm-specific parameters already exists, there are two init methods that have an AlgorithmParameterSpec argument. One also has a SecureRandom argument, while the other uses the SecureRandom implementation of the highest-priority installed provider as the source of randomness (or a system-provided source of randomness if none of the installed providers supply a SecureRandom implementation).

Aes Key Absent

You can use the keytool shipped with the encryption proxy distribution to create AES 128-bit and AES 256-bit encryption keys. Product documentation Docs. Key generator chief architect x8. Create encryption keys using the Java KeyStore keytool. Save as PDF Selected topic Topic & subtopics All topics in contents. 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. For example, I have a secret key for AES on my server and a counter in my database. Each time I want to generate a random number I increment the counter then encrypt it with AES using the secret key on my server then transform the resulting bits into the right number. Wouldn't this produce secure random number as long as my secret key is not found? AES-256 Encryption with Java and JCEKS. Generate SecretKey. This is the flag indicating the creation of a synchronous key which will become our AES key. The AES key is nothing more than a. A strong AES key will be 16, 24, or 32 bytes long. If you restrict the key to bytes that map to printable US-ASCII characters, the key will be weaker than expected, because its range is limited (to about 100 bits, rather than 128—many millions of times weaker). Generate a random 128-bit key (k1), a random 128-bit IV, and a random salt (64 bits is probably sufficient). Use PBKDF2 to generate a 256-bit key from your password and the salt, then split that into two 128-bit keys (k2, k3). Make sure your algorithm's native output is at least 256 bits, or this will be slow. PBKDF2- SHA256 is a good choice.

In case the client does not explicitly initialize the KeyGenerator (via a call to an init method), each provider must supply (and document) a default initialization.

Every implementation of the Java platform is required to support the following standard KeyGenerator algorithms with the keysizes in parentheses:

• AES (128)
• DES (56)
• DESede (168)
• HmacSHA1
• HmacSHA256

These algorithms are described in the KeyGenerator section of the Java Cryptography Architecture Standard Algorithm Name Documentation. Consult the release documentation for your implementation to see if any other algorithms are supported.
