Cryptography in Practice: TLS, JWT, and SSH

How everyday protocols such as TLS, JWT/JWS, and SSH combine symmetric keys, public keys, signatures, key exchange, and PKI, viewed through the three uses of a public key and backed by RFCs. The final part of a three-part cryptography series.

Key Exchange and PKI: Diffie-Hellman, Certificates, and Certificate Authorities

How Diffie-Hellman shares a symmetric key safely, how ECDHE adds forward secrecy, and how PKI binds a public key to its owner through certificates, CAs, and a chain of trust. Backed by primary sources such as RFCs. Part 2 of a three-part cryptography series.

HTTP and SSL/TLS

Understand how HTTPS works: TLS handshake after TCP, confidentiality/integrity/authenticity, the history from SSL vulnerabilities to TLS 1.2/1.3, and why universal HTTPS adoption happened.
