Minicrypto

Tiny, zero-dependency cryptographic primitives library for D language. Its main use case is building custom secure transport layers, e.g. for online games, VoIP and IoT.

Most of it is a direct port of Monocypher C code to D, retaining Monocypher API.

Why another crypto library?

Most existing libraries are bloated with legacy crypto primitives that should not be used for building new stuff. Trying to support every existing standard makes them over-engineered and confuses users. Minicrypto provides only a minimal set of modern algorithms. It is not a binding nor a wrapper around system cryptography, and has no dependencies, which makes usage easy and straightforward. Also Minicrypto is the only known @nogc and betterC-compliant crypto library for D. Manual memory management is preferable in real-time applications and a strict requirement for system development.
