2. I am interested in creating a licence file which will authenticate the use of a Java application. The application will open showing a window if the licence is not found or is invalid. I also want to create a licence generator program which I can use (probably obvious) to create licence files.
3. License4J License Manager and Library for Software Licensing Features. License4J comes with many licensing features and serial number generation methods and required validation methods implemented.

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.

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. The licence key problem is easy, decide on HOW the licence key will be checked, for example summing the digits adds up to 93, then write a simple function to generate them. Personally, I use a hash code from the registration details, e.g. The user's email. To make an exe is not trivial.

Serial Key Generator is application specially designed for software developers to help protect your applications by serial key registration. Just in a few clicks you are able to generate serial. .

Nor are there any bits that have a specific meaning as in (3)DES parity bits. In principle AES keys can have any value. There are no 'weak keys' as in (3)DES. This means that the code may be optimized for this generation. Java generate aes symmetric key. So generating a key can be as simple as generating a byte array with random values, and creating a SecretKeySpec around it.But there are still advantages to the method you are using: the KeyGenerator is specifically created to generate keys.

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).

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.
