Cryptography Fundamentals: Symmetric, Asymmetric, One-Way Functions, Hashing, and Digital Signatures

From symmetric versus asymmetric encryption to the one-way and trapdoor functions behind RSA and ECC, plus hash functions and digital signatures, this article explains the building blocks of cryptography with primary sources. Part 1 of a three-part series that groups public-key uses into signing, encryption, and key exchange.

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.

Three Uses of a Public Key: Signing, Encryption, and Key Exchange

A public key has just three uses: signing, encryption, and key exchange. This article sorts real-world applications such as SSH public-key auth, WebAuthn, mTLS, private_key_jwt, code signing, and container signing into these three, and clarifies how they differ from shared-key schemes such as HMAC, with primary sources.
