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.

Thank you for the random number site. Our university, in a campaign of privacy protection, has forbidden us faculty to use any part of student social security numbers to post grades, nor may we use any part of the randomly assigned new student ID numbers that replaced the social security numbers. Using your very friendly site, I was able to generate all the 4-digit numbers I'll ever need to assign to students for grade-posting purposes.
