ASCII Font URL Encryption

I was looking at some source code the other day and found some 3D ASCII text.

It brought back memories of using UNIX and PINE for e-mail during my college days.

I decided to go on a hunt for the 3D ASCII font and found this siteโ€ฆ http://patorjk.com/software/taag/

Once you find the font that you likeโ€ฆ

then you can create a link to share with others, but I noticed something strange in the URL

http://patorjk.com/textart/msg1.php?font=Larry%203D.flf&hs=true&bg=%23FFFFFF&fc=%23000000&align=left&txt=Ryvwnu

Do you notice anything strange about the txt URL parameter? โ€œRyvwnuโ€โ€ฆ what is that? Well, it stands for โ€œElijahโ€

I put on my cracker hat and found that it was a simple character substitution algorithm. Take the letter you want โ€œEโ€ and add 13 characters to it โ€œRโ€.

How is that for some advanced encryption ;)
