So, I wrote this little thing a couple days ago. I was browsing on Geocaching.com and wanted to decode some of the hints. I found a few ROT13 decoders online, but wanted to write one of my own.

Much to my dismay, I learned geocaching.com has a built-in “decode” link right next to the encoded hints. I didn’t learn about this until about 10 minutes after I had finished writing the Geocaching Hint Encoder/Decoder. Thankfully, I didn’t have more than 20 minutes of work into it, so no big deal.

Geocaching Hint Encoder/Decoder was made with PHP and jQuery. I even put all the code up on Github so you can have a look for yourself!
