The trickyness of this -translation is that it needs to be aware of certain special names contained -in the structure `SpecialNames`. Indeed, while the Rust AST treats the application -enum constructors like function applications, the hacspec AST considers them as -proper injection so we need to distinguish them in the Rust AST. For that, we -need to know all declared enums at this point of the program. - -Enums and other `SpecialNames` are also defined in the `ExternalData` that -contains the signatures and types imported in crates used by the hacspec -program being compiled. - -### Name resolution - -When the translation from Rust AST is finished, the identifiers for all -variables inside function bodies are of the following type: - -```rust, noplaypen -pub enum Ident { - Unresolved(String), - Local(LocalIdent), - TopLevel(TopLevelIdent), -} -``` - -More precisely, they are still in the `Ident::Unresolved` case. The compiler -pass in `name_resolution.rs` resolves the identifiers by linking them to local or global identifiers, -each one having a unique ID. hacspec does not feature De Bruijn variable -handling, instead relying on unique fresh IDs for differentiating local -and global variables from each other. - -### External data - -A hacspec file can never (in principal) be considered alone, as it usually imports -at least several other crates like the hacspec standard library. These external -crates must pre-populate the typechecking context with the types and function -signatures that they define. - -It's the job of `hir_to_rustspec.rs` to retrieve this data. The critical -piece of code in this file is [the following](https://github.com/hacspec/hacspec/blob/cc609254b0aa978646f494291b9c91a92fe107ee/language/src/hir_to_rustspec.rs#L733-L737): - -```rust, noplaypen -let num_def_ids = crate_store.num_def_ids_untracked(*krate_num); -let def_ids = (0..num_def_ids).into_iter().map(|id| DefId { - krate: *krate_num, - index: DefIndex::from_usize(id), -}); -``` - -First, we retrieve the number of exported symbols by an external crate using -`num_def_ids_untracked`, a function that is [specifically labeled](https://github.com/rust-lang/rust/pull/85889) -as critical to the hacspec compiler in the Rust compiler codebase. Then, -we manufacture definition IDs for all these exported symbols, relying on the -invariant that they are numbered from 0 to the number of exported symbols -in Rust's compiled crate metadata format. - -Then, we use those definition IDs (`DefId`) to query the Rust compiler -via the central [`TyCtxt`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/ty/struct.TyCtxt.html) -data structure. If the `DefId` corresponds to a type definition, we examine the -type definition structurally and check whether it corresponds to a hacspec-compatible -type definition. Notably, the type definitions generated by macros like `array!` -or `nat_mod!` are only seen here in their expanded version, so we have to retro-engineer -which expanded version corresponds to which macro expansion. This is a vulnerability -of the compiler since it's possible to break the abstraction of the language -by smuggling in a type not defined via a hacspec macro this way. That's why hacspec -developers should be very careful about which dependencies they import in order -to have a 100% safety guarantee. - -For `DefId`s corresponding to functions, the signature of the function is analysed -and if it fits the subset of types expected by hacspec, the function is imported -along with its type in a pre-populated typechecking context. - -Note that it is not possible any more at this point to retrieve the `#[in_hacspec]`, -`#[unsafe_hacspec]`, etc. attributes that would tag the external definitions, -since these attributes get erased by the Rust compiler before reaching the -compiled crates metadata. - - -### Typechecking - -The typechecking is done in `typechecker.rs` and follows a very regular structure, -making heavy use of immutable data structures to not mess up the various -context manipulations. - -Note that we need to perform a full typechecking complete with method resolution -because the proof backends need very fine-grained typechecking information -to generate correct code. - -Be careful: types often need to be de-aliased with `dealias_type` before -being matched on structurally. Forgetting to dealias will lead to bugs with -type aliases. - -### Proof backends - -The different proof backends (`rustspec_to_fstar.rs`, etc) all enjoy a similar -structure that ought to be refactored to showcase their commonality. The backends -don't use an intermediate AST to generate the code in the proof assistant but -rather directly print code as string using the [`pretty`](https://crates.io/crates/pretty) -pretty-printing library. If you want to start a new proof backend, the easiest -solution is probably to copy an existing proof backend and tweak it until -you get the right result. - -The code generation has to be fine-tuned to interface with a replica of the -hacspec standard library in the host proof assistant, whose correspondence with -the original hacspec library in Rust is part of the trusted code base.

Cryspen also supports an experimental backend for +[ProVerif](https://bblanche.gitlabpages.inria.fr/proverif/). + +With this initial release, hax can process a significant subset of Rust code. +Both the frontend, which extracts a JSON AST from the Rust compiler, and the +engine, which lowers the code to the backends, have undergone major +improvements and stabilization throughout 2024. + +Our new website provides a central hub for all things hax. +Users can explore the [manual](../../manual/index.md), experiment with the +interactive [hax playground](https://hax-playground.cryspen.com/), +and delve into a diverse collection of [examples](https://github.com/cryspen/hax/tree/main/examples) +showcasing hax's capabilities. + +We will work on improving the manual and developer documentation over the next +few months. + +#### Hax in Action + +Over the past year, hax has proven its versatility in various projects: + +- [Verifying Bertie](https://cryspen.com/post/hax-pv/): A TLS 1.3 implementation, verified with the ProVerif backend +- [Verifying ML-KEM](https://cryspen.com/post/ml-kem-verification): A post quantum cryptographic algorithm verified with the F\* backend +- [Verifying Smart Contracts](https://github.com/hacspec/hacspec.github.io/blob/master/coqpl24-paper9-13.pdf): Leveraging the Rocq backend for enhanced security verification. + +#### The Road Ahead + +While hax can handle a substantial portion of Rust code, certain limitations +remain. +Features like Generic Associated Types (GATs), some Rust nightly features, specific +loop and pattern structures, and a range of mutations are not yet supported. + +???

+# Introduction
+
+hax is a tool for high assurance translations of a large subset of
+Rust into formal languages such as [F\*](https://www.fstar-lang.org/) or [Rocq](https://rocq-prover.org/).
+
+## Usage
+
+Hax is a cargo subcommand. 
+The command `cargo hax` accepts the following subcommands:
+
+* **`into`** (`cargo hax into BACKEND`): translate a Rust crate to the backend `BACKEND` (e.g. `fstar`, `coq`).
+* **`json`** (`cargo hax json`): extract the typed AST of your crate as a JSON file.
+ 
+Note:
+
+* `BACKEND` can be `fstar`, `coq`, `easycrypt` or `pro-verif`. `cargo hax into --help`
+   gives the full list of supported backends.
+* The subcommands `cargo hax`, `cargo hax into` and `cargo hax into
+   ` takes options. For instance, you can `cargo hax into
+   fstar --z3rlimit 100`. Use `--help` on those subcommands to list
+   all options.
+
+## Installation
+
+### Manual installation
+
+1. Make sure to have the following installed on your system:
+
+      - [`opam`](https://opam.ocaml.org/) (`opam switch create 5.1.1`)
+      - [`rustup`](https://rustup.rs/)
+      - [`nodejs`](https://nodejs.org/)
+      - [`jq`](https://jqlang.github.io/jq/)
+
+2. Clone this repo: `git clone git@github.com:hacspec/hax.git && cd hax`
+3. Run the [setup.sh](./setup.sh) script: `./setup.sh`.
+4. Run `cargo-hax --help`
+
+### Nix
+
+This should work on [Linux](https://nixos.org/download.html#nix-install-linux), [MacOS](https://nixos.org/download.html#nix-install-macos) and [Windows](https://nixos.org/download.html#nix-install-windows).
+
+Prerequisites: Nix package
+manager (with flakes enabled)
+
+  - Either using the [Determinate Nix Installer](https://github.com/DeterminateSystems/nix-installer), with the following bash one-liner:
+    ```bash
+    curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install
+    ```
+  - or following [those steps](https://github.com/mschwaig/howto-install-nix-with-flake-support).
+
++ **Run hax on a crate directly** to get F\*/Coq/... (assuming you are in the crate's folder):
+   - `nix run github:hacspec/hax -- into fstar` extracts F*.
+
++ **Install hax**:  `nix profile install github:hacspec/hax`, then run `cargo hax --help` anywhere
++ **Note**: in any of the Nix commands above, replace `github:hacspec/hax` by `./dir` to compile a local checkout of hax that lives in `./some-dir`
++ **Setup binary cache**: [using Cachix](https://app.cachix.org/cache/hax), just `cachix use hax`
+
+### Docker
+
+1. Clone this repo: `git clone git@github.com:hacspec/hax.git && cd hax`
+2. Build the docker image: `docker build -f .docker/Dockerfile . -t hax`
+3. Get a shell: `docker run -it --rm -v /some/dir/with/a/crate:/work hax bash`
+4. You can now run `cargo-hax --help` (notice here we use `cargo-hax` instead of `cargo hax`)
+
+Note: Please make sure that `$HOME/.cargo/bin` is in your `$PATH`, as
+that is where `setup.sh` will install hax.
