The UDC is a shareware program. Therefore unregistered version has some limitations creating inconveniences at work with the program. For instance, unregistered version of progam can not delete single user hash, it allows only clearing the whole list. More than 2 minutes in distributed mode is prohibited, and single-computer evaluations are also time-limited.

Thus, the demo can be used unless for an estimation of speed of performance of attack, and also, for very simple computational problems. In case it is needed to solve more complex computational problem, it is necessary to use the full version of software product.

The full version differs from a demo in content of library NewUDC.dll which represents the basic component of the passwords cracker. Some functions have not been included in a binary code of a demo version, therefore for getting of the fully-functional version it is needed to replace this file. The program uses a hardware-dependent Identification Code for registration, therefore the registered copy can be performed only on that computer for which registration was made.

The cost of the full version is $37.

The Identification Code will be shown at each execution of a demo version. By clicking the reference "Click here to register the program" the registration e-mail will be generated, having sent which on register [at] The-UDC.com and having made translation of the $37 to me, you'll receive by e-mail the installation package containing the full version of NewUDC.dll, corresponding to your Identification Code.

Once you've registered program, if your configuration is changed (just e-mail about it), you'll get the full version of UDC without any additional payment.
