Orthrus: SD card secure RAID USB storage
This project is a hardware mechanism to provide secure "two man control" over a data store. It is a USB microSD card reader, but it requires two cards. The data is striped in the style of RAID 0, but the data is also encrypted with a key that is stored in a key storage block on each card. In essence, each card is useless without the other. With possession of both cards, the data is available without restriction, but with only one, the remaining data is completely opaque.

This allows you to securely transport a data set by writing it onto a pair of cards and separately transporting them to a destination for recombination.

The Illustrated TLS 1.3 Connection: Every Byte Explained
Every byte explained and reproduced

A revised edition in which we dissect the new manner of secure and authenticated data exchange, the TLS 1.3 cryptographic protocol.

In this demonstration a client connects to a server, negotiates a TLS 1.3 session, sends "ping", receives "pong", and then terminates the session.

ALSO: a really cool example of how to present data
