An Example ECDH Key Exchange with HKDF and Authenticated Encryption in Rust

I recently created an example project which implements an ephemeral key exchange between a client and server over TCP. The program uses the Ring cryptography library to compute a shared secret using the X25519 algorithm. Two session keys are derived from the output of the key exchange using HKDF and… Read More »An Example ECDH Key Exchange with HKDF and Authenticated Encryption in Rust

ECDH Key Agreement in Rust using Ring

In this post I show you how to implement an ECDH key exchange using the agreement module of the Rust cryptography library Ring. We will go through generating a public/private key pair, exchanging public keys with a peer and then using the agree_ephemeral function to securely compute a shared secret.… Read More »ECDH Key Agreement in Rust using Ring
