Ring is a popular Rust cryptography library which has support for generating cryptographic keys from a single input key using HKDF, the HMAC-based Extract-and-Expand Key Derivation Function. As you will see in this post, the ring::hkdf module supports securely generating pseudorandom bytes using the Salt::extract and Prk::expand methods implemented in… Read More »Deriving Cryptographic Keys with HKDF in Rust using Ring
Ring is one of the most popular Rust cryptography libraries and it provides a way to securely generate random numbers by using the ring::rand module. In this post I will show you how to generate random numbers correctly using the types provided by Ring. PRNGs vs CSPRNGs Computers are deterministic… Read More »Generating Random Numbers in Rust using Ring
In my previous post I introduced the Rust cryptography library Ring (see here). In this post I will show you how to use Ring to sign and verify messages using the HMAC algorithm. Introduction to HMAC First a bit of cryptography theory. There are four main properties which we would… Read More »Signing and Verifying Messages with HMAC in Rust using Ring
Ring is an open source cryptography library that implements cryptographic primitives and is designed to have an easy to use interface. It is implemented in Rust, C and assembly and most of the C and assembly language code in ring comes from BoringSSL. It supports the following features: You can find the… Read More »Cryptographic Hash Functions in Rust using Ring
