Learning Quantum Cryptography by Doing It

PQSW is a secure transport layer (like TLS) implemented using modern quantum resistant cryptography from scratch, for learning and fun (I can not say it can be used commercially as it has not been audited, but it has been done properly, it is not a toy project.)

We explore one-time-pads, client puzzles, session key derivation, how to optimise the encryption envelops for network traffic, and some other intricancies.
