Rnd Module

Properties   Methods   Events   Configuration Settings   Errors  

The Rnd component class is a basic provider of random number generation functionality.

Syntax

nsoftware.SecureBlackbox.Rnd

Remarks

Use Rnd control to generate pseudo-random numbers or sequences. Methods like NextBytes and NextInt return the next PRNG output, whereas SeedBytes or SeedInt seed the generator with outside entropy.

It is a good idea to use one shared (singleton) Rnd object per process, as it helps spread the entropy across many part of the project, resulting in better and more secure randomization.
