#99011 — Public key encryption example.

This might be a "Let me Google that for you question", I tried.
I am looking for the "simplest" example of sending(encrypting) and
receiving(decrypting) using public key encryption. I am think of something
along the lines of having all the keys in local files and saving and
reading the message from a local file.

Possibly using cryptography library elliptic-curve
https://cryptography.io/en/latest/hazmat/primitives/asymmetric/ec/#elliptic-curve-signature-algorithms

Surly there is an example out there?

It's very easy to make mistakes doing stuff like that.  Your simplest
bet is to shell out to GPG or something comparable.

It's not that hard to pull up a library. I've never done it in Python, though.

Found an example, needs a little updating but then it works (appears to) in
python 3.5.
