I was working on a project recently that required unique API keys to be generated for clients connecting to the server. For various reasons, I settled on the style of license key you commonly see for software packages. You know, the kind you always had to read off the back of a CD case and type in when installing the application. Like H8OV7-HNTB5-JLLOH-W8FG2.

Feb 12, 2009  Example Product Key generator - posted in Professional Code: I decided to stray away from using a RSA generated public key as a license key, because it is not easily human readable. Instead, I designed a very simple key generator that outputs keys in the well known 25 character format XXXXX-XXXXX-XXXXX-XXXXX-XXXXX The key generator does not simply generate a unique random product key.

It’s fairly easy to write such a function. Apple developer generate push notification key. The basic idea is to loop around four times—once for each segment—and have a nested loop that runs five times, picking a random character each time. Here’s what I came up with:

The $tokens string contains the characters that are valid in the key, so the loop can pick from it. The $segment_chars and $num_segments variables are the number of characters in a segment and the number of segments in the key, respectively. $key_string is an empty string that the loop will add the characters into.

The first for loop runs four times, assuming the desired result is four segments in the key. The inner loop picks a character out of $tokens at random each time it goes around. (PHP strings are also arrays, with the each character having its own numerical offset.) The characters are tacked onto the $segment string.

Then the segment is joined with the $key_string, and a dash character is applied if the loop isn’t on the final segment yet. End result: something like H8OV7-HNTB5-JLLOH-W8FG2.

You generate a new key string with the function, check to see if it exists in your database, and lather/rinse/repeat until that is no longer the case. Usually you won’t have collisions too often, so it will only need to run once. I’m too lazy to figure out the probability, but considering there are 52,521,875 possible combinations for one 5-character segment…you’re probably not going to run into performance issues anytime soon. And if you do, just add another segment onto your key strings.
