I knew (possibly extra) encryption wasn't necessary at this stage, but I 
also knew that encryption would provide good obfuscation.  Problem is, I 
didn't want an extra C library to install. See the original post.

"... I'd like to protect the recipient against exposure to nefarious 
data by mangling or encrypting the data before it is written to disk. My 
original idea was for the recipient to encrypt using AES.  But I want to 
keep this software pure Python "batteries included" and not require 
installation of other platform-dependent software ... I don't know that 
I really need encryption here, but some type of fast mangling algorithm 
where a bad actor sending a payload can't guess the output ahead of time."
