The Base64 Encoder Has a Fixed Point

Francisco Mota (via Reddit):

Every time we encode, we get the same string back with a few changes at the end. This isn’t on purpose, this is a purely accidental consequence of base64’s design. There was never any point where the designer of base64 decided “Let there be a long string s that is a prefix to its own representation in base64!”
