In several things that I do, I require some form of randomness (for example, secure primary keys for databases, with almost no chance of collision error). To do this, I use your site to create them. A simple generation of numbers between 0 and 35, and then change them into their base-36 equivalent, however long the sequence needs to be, and you have an virtually unguessable primary key sequence. You can’t guess what the next key in the sequence will be. Very useful for keeping people from being able to hack your customer list and finding out who does business with you (they might be able to guess one, but the next won’t be sequential, so they would have to start all over again to find the next). I also use it in my writing, to generate datasets for locations and people by assigning integers to various items and using the site to pick the ones that apply.

It was a pleasure using your extremely quick and efficient random number generator service.

I'm currently using it to assign authentication codes to the users of my PBX system, so I know who's authorized to make international calls, etc. I was facing the problem that if I started assigning authentication codes in serial order, people might guess others' authentication codes and misuse them.

I wish to thank you for putting up this free service for the use of one-shot users like me, I really appreciate it.
