uuidgen

If you need to identify information in a computer system, you've probably heard about Universally Unique Identifiers, or shortly UUIDs.

uuidgen is one of the applications that can be used to generate these identifiers that are widely used in software development.

A UUID is a 128-bit number that is used to identify information on computer systems, as stated above. You might encounter the term GUID (Globally Unique Identifier), which represents the same thing.

Unlike other numbering techniques, the UUIDs don't depend on a central registration authority and there's no coordination between the parties that are used to generate them, as the probability that two identical UUIDs will be created is near zero.

uuidgen is a lightweight application that can help you generate these random identifiers directly on your computer so that you can use them in software development or other activities.

Since it has been written in Java, it is worth mentioning that you will need Java Runtime Environment to be installed on your computer before attempting to use this app.

Since it is portable, uuidgen doesn't require you to install it on your computer, as simply launching it grants you full control over its functions. More so, it won't create additional files or folders on your computer, nor will it tamper with your Windows Registry entries.

You should also note that, unlike other Java apps, this one doesn't pack a graphical user interface (GUI), but can only be used through a command prompt. In order to use it, open a CMD window and type "java -jar" and the path of the app. If the CMD is already set to the root folder of the app, you simply need to input its name after the "java -jar" fragment.

If you want to generate UUIDs quickly on your computer and have a bit of experience with CMD, you can count on uuidgen, as it has everything you need.
