swanky: A suite of rust libraries for secure computation

swanky provides a suite of rust libraries for doing secure computation.

• fancy-garbling: Boolean and arithmetic garbled circuits.
  • twopac: Two-party garbled-circuit-based secure computation.
• humidor: Implementation of the Ligero zero knowledge proof system.
• keyed_arena: Bump allocator which allows for random access to its allocations.
• inferno: An implementation of the Limbo zero-knowledge proof system.
• ocelot: Oblivious transfer and oblivious PRFs.
• popsicle: Private-set intersection.
• scuttlebutt: Core primitives used by other swanky crates.
• simple-arith-circuit: Simple flat arithmetic circuit representation.

A note on security

swanky is currently considered prototype software. Do not deploy it in production, or trust it with sensitive data.

Using swanky

Preferred Way

The preferred way to use swanky is to fork this monorepo, and add your code to your fork. This approach makes it easy for your code to inherit the configuration of the swanky repo.

Alternative Way

It is also possible to use swanky as traditional Rust crates. The downside of this approach is that you won't automatically get the configuration of the swanky repo. swanky is only tested against the pinned rust version in the repository and the pinned dependency versions.

To use a swanky crate in your project, add the following line to the [dependencies] entry in Cargo.toml:

<crate-name> = { git = "https://github.com/GaloisInc/swanky", rev = "xxxxxx" }

where <crate-name> is one of the crates listed above and rev is the particular revision to use.

Note: As swanky is currently considered prototype software, it is best to pin a particular revision of swanky, as there is no guarantee that future versions of swanky will maintain backwards compatibility.

It is also advisable to copy over swanky's .cargo/config file, and to enable LTO in your release builds (lto = true in your Cargo.toml file).
