[!CAUTION]

Development in Progress

This project is currently in development and not yet ready for production use.

Expect changes to occur from time to time, and at this stage, some features may be unavailable.

About

openssl_provider_forge is a Rust crate which contains FFI (Foreign Function Interface) bindings for OpenSSL 3.2+, specifically for its Core and Provider API.

This is different from the rust-openssl crate, which provides OpenSSL bindings for Rust applications.

In this crate, instead, we define constants and types useful to author OpenSSL Providers written in Rust. The goal of this crate is to facilitate interactions with OpenSSL Core, without a need to actually link or depend on a specific OpenSSL binary.

Particularly these abstractions cover:

• openssl-core
• openssl-provider-base

(and their dependencies).

[!NOTE] Note on naming conventions

The name of the repository follows Github conventions, while the name of the corresponding crate follows crates.io conventions, so the former is openssl-provider-forge-rs while the latter is openssl_provider_forge.
