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.

Just a quick note to say thanks for providing the service. I use a lot of things on the internet that almost do what you want, but Random.org saved me lots of time and gave me just what I wanted. I used it to generate lengths for some fibre optic lighting I'm having installed, just went through after and modified any adjacent numbers the same and it gave me exactly what I wanted. Easy to set the limits and size and shape of number results—great.
