Generating 128 bit random key in java. Ask Question Asked 5 years, 11 months ago. Active 3 years, 2 months ago. Viewed 13k times 4. I want to generate a 128 bit. We will need some kind of salt and hashing function to convert a password to the desired key. However, let's assume the password is automatically generated for every file anyway. This means that we can theoretically skip the salt and hash (e.g. Pbkdf2), and just generate a random 256 bit key and 128 bit iv. Random Password Generator. Of transferring byte chain in 128 bit with some. ZIP using the encryption of data with AES with the key length of 256 bit.

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.
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:

The KeyGeneratorinit() method takes two parameters: The bit size of the keys to generate, and a SecureRandom that is used during key generation.
Generating a Key
Once the Java KeyGenerator instance is initialized you can use it to generate keys. Generating a key is done by calling the KeyGeneratorgenerateKey() method. Here is an example of generating a symmetric key:
