Cryptography is the science of applying algorithms to data in a way that requires at least one key to "unlock" it. It could be as simple as a child's decoder ring, or it could be complex enough to require thousands of computer years to crack.
Crypto is often the only way to protect your privacy on insecure or monitored channels. It seems like a really good time to talk about how to do that!
Let's talk about:
- a brief history of crypto, to show why it's relevant, how governments historically react to crypto, and to put today's crypto in context
- An explain-like-I'm-five demonstration of symmetrical and asymmetrical encryption, and how public key infrastructure (PKI) works
- Cryptographic ciphers, and their current state of security
- Examples of crypto in recent news and court cases, and your rights re: crypto (I am not a lawyer, so do not take this section as legal advice)
- Finally, a practical discussion of free crypto solutions to protect your privacy in email, storage, VPN, and things like onion routing. We could also do an installation workshop if you want to bring your computer or laptop.
I am an information security professional currently getting my MS in Information Security Engineering with an emphasis on digital forensics. Crypto is a personal interest of mine and I'm happy to share based on my desire to share knowledge and protect privacy in the currently invasive world of the Internet.
