Pretty Good Post Quantum Privacy (PGPQP)

PGP does not currently implement post quantum cryptography. This project aims to provide a PGP-like system that does.

Motivation

I wrote a paper on post quantum cryptography during my sophomore year of my Bachelor's degree in cybersecurity. For the same class--about a week prior--I wrote another paper discussing the importance of consumer end-to-end encryption (E2EE). I thought it would be a good idea to combine the two ideas and create a post quantum cryptography system that could be used in place of PGP.
