Rust secret integers

This simple crate provides integer wrappers that guarantee that they are being used in a constant-time fashion. Hence, division and direct comparison are disallowed. Using Rust's type system, this crate will help the compiler check systematically whether your cryptographic code is constant-time relative to secret inputs.

To use the crate, just import everything (use secret_integers::*;) and replace your integer types with uppercase versions of their names (e.g. u8 -> U8).

Examples

Two examples show how to use the crate : Dalek and Chacha20. To build theses examples, use

cargo build --example dalek
cargo build --example chacha20
