I just got reminded by timehop of something I shared a few years back and wanted to share it again but talk about it a little more in dept. It’s an interesting subject if you know the ideas and problems addressed by cryptography, this one is about base64. It address the issue that, if we encode something in base64, then encode the result using the same method, the more we repeat this the closer we come to a fixed point the method hits. That is to say base64 has point where it will give you the same answer as the product you passed in.

This issue was looked into by Fran Mota who is a computer science student (according to his website at the time of writing) at Cornell University. Fran created the post The Base64 Encoder Has A Fixed Point back in 2013, so all credit to him for his…
