At this MeetUp, Chris Campbell - a big fan of cold war history and spy tactics - will dive deep into an application he developed to take care of a small but important task: sharing secrets.

A dead drop is a method of exchanging secrets between two agents, whereby the secret is stored in a safe, predetermined location for collection, thus meaning that the two agents never have to meet and are able to maintain operational security. Where there is concern that a drop may be compromised, an additional key to decrypt the secret may be transferred using a different channel. This method was incredibly popular and effective during the cold war, and served as the inspiration for Chris' application "DeadDrop (https://deaddrop.jadeworld.com/)". In fact, the inspiration for DeadDrop goes beyond the time of the cold war and into the present, realising that there is a decreasing level of trust in service providers - so also offers a "host proof" mode of operation and is open-sourced. Gone are the days of transferring secrets (e.g. credentials) in plaintext emails and texts.

This session will look into a few aspects of DeadDrop:

• A short history lesson: the inspiration for DeadDrop

• The importance of OPSEC in our daily lives

• The theory behind effective secret sharing

• Cryptography 101.

• .NET and JS cryptographic considerations

• Code breaking 101.Chris • Wed, 8:11 PM
