> **OxiTLS vendored fork.** This is a copy of
> [`rustls-rustcrypto`](https://github.com/RustCrypto/rustls-rustcrypto) vendored
> into the OxiTLS workspace as the `oxitls-rustcrypto-provider` crate. It exists
> to fix **RUSTSEC-2026-0104** — a CRL-parsing panic in `rustls-webpki` 0.102.x.
> The patched copy drops the vulnerable `rustls-webpki` dependency and routes
> `alg_id` through `rustls-pki-types` instead. It **is** a full workspace member
> (see the root `Cargo.toml` `[workspace] members` list); the root `Cargo.toml`
> resolves the `rustls-rustcrypto` workspace dependency to this crate via a
> package rename (`rustls-rustcrypto = { package = "oxitls-rustcrypto-provider",
> ... }`), not a `[patch.crates-io]` override. The original upstream README
> follows unchanged.

[RustCrypto]-based provider implementation for version 0.23 of [rustls], maintained by the RustCrypto organization.
## ⚠️USE THIS AT YOUR OWN RISK! DO NOT USE THIS IN PRODUCTION⚠️
Not only that this is incomplete that only few selected TLS suites implemented (it should be well enough to cover 70% of the usage), but the elephant in the room is that neither did rustls nor RustCrypto packages were formally verified and certified with FIPS compliance.
Note that RustCrypto performance is generally inferior than ring, but in exchange you got a pure Rust implementation that theoretically compiles everywhere Rust was ported to. In our case, we need to have `std` but foundational support for future `no_std` expansion is already here.
