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

License Key

• Using a 20 letters short serial key, you can store a lot of useful information, such as dates, features, time limits, etc. You can either use the library itself, by adding it as a reference to your Visual Studio project, or by using an already existing GUI - Software Protector.
• What algorithm can I use to generate reasonably secure keys that embed username, product id, and version number, where the resulting license key is no longer than 30 characters and uses only digits and upper-case characters? (If important, we're coding in Java.) So.here's a start.
• 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.

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

Java License Key Generator Open Source 2017

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.

  /software-license-key-generator-open-source.html. 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.

Open Source Java For Windows

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.
