Perl Password Poetry Producer

There’s a fun little geeky comic online that you may have heard of, XKCD.

A while back the author had comic that resonated with me about password security. I’m not buff enough in my math skills to keep up understand the equation but I could follow the principle. The idea is that four (or so) random words is more secure than making an extremely complex password that has numbers and special characters embedded and replacing letters. The challenge with this somewhat standard practice of l33tspeak is it has to be written down. But… since we are people that love stories, four random words in real English will be more memorable because we can make up a story to remember it.

Here’s the famous comic.

Recently, while I was working on one of my other Perl scripts, I was on an online forum and saw a post about how to make a random sentence. That tickled my fancy and I came up with a quick and dirty little CGI script to generate a random sentence suitable for passwords. Unfortunately a lot of places have requirements to still include special characters and numbers but this little script will meet those requirements. The spaces meet special character requirements (most of the time) and a number between 1 and 99 is included.

The results? They are often amusing and poetic. Sometimes they are risque. It just depends on what is in your system’s local dictionary. Download Perl Password Poetry Producer
