<p>Cryptography is a method of protecting information and communication through the use of code so only those for whom the information is intended can read and process it. Cryptography is used for many things from online banking to GitHub commits. Today we’ll dive into the basics of cryptography. Let’s get started!</p> <h1>Show Notes</h1> <ul> <li>[0:25] Our experience with cryptography</li> <li>[03:08] What is cryptography?</li> <li>[04:21] Four objectives of cryptography</li> <li>[09:44] Types of cryptography</li> <li>[23:34] Historical Cryptography</li> <li>[30:54] How to learn cryptography</li> <li>[32:34] Shoutouts</li> </ul> <p>We got this note about RSA private/public keys from a listener: </p> <p>"The point of having public and private keys is that the public key can only encrypt a message, and only the private key can decrypt the message. So the public key is safe for anyone to have, since you can’t use it to read anyone else’s message. The private key needs to stay private so only you can read messages encrypted by the public key"</p> <p>Thanks for the clarification, Brad!</p> <h1>Resources</h1> <ul> <li>Coursera course - <a href="https://www.coursera.org/learn/crypto#syllabus" rel="nofollow">https://www.coursera.org/learn/crypto#syllabus</a></li> <li>Crash course - <a href="https://www.youtube.com/watch?v=jhXCTbFnK8o" rel="nofollow">https://www.youtube.com/watch?v=jhXCTbFnK8o</a></li> <li>Khan academy - <a href="https://www.khanacademy.org/computing/computer-science/cryptography" rel="nofollow">https://www.khanacademy.org/computing/computer-science/cryptography</a></li> <li>Passport JS - <a href="http://www.passportjs.org/" rel="nofollow">http://www.passportjs.org/</a></li> <li>OAuth - <a href="https://oauth.net/2/" rel="nofollow">https://oauth.net/2/</a></li> <li>Episode with Tailor Tolliver on security - https://www.ladybug.dev/episodes/web-security?rq=security</li> <li>The Code Book by Simon Singh - <a href="https://www.amazon.com/Code-Book-Science-Secrecy-Cryptography/dp/0385495323" rel="nofollow">https://www.amazon.com/Code-Book-Science-Secrecy-Cryptography/dp/0385495323</a></li> <li>Carcassonne - <a href="https://boardgamegeek.com/boardgame/822/carcassonne" rel="nofollow">https://boardgamegeek.com/boardgame/822/carcassonne</a></li> <li>Auth0 - <a href="https://auth0.com/" rel="nofollow">https://auth0.com/</a></li> <li>Amazon Cognito - <a href="https://aws.amazon.com/cognito/" rel="nofollow">https://aws.amazon.com/cognito/</a></li> </ul> <h1>Transcript</h1> <p><a href="https://github.com/ladybug-podcast/ladybug-website/blob/master/transcripts/67-cryptography.md" rel="nofollow">https://github.com/ladybug-podcast/ladybug-website/blob/master/transcripts/67-cryptography.md</a></p>
