RustCrypto: Cryptographic Big Integers
Pure Rust implementation of a big integer library which has been designed from the ground-up for use in cryptographic applications.
Provides constant-time, no_std-friendly implementations of modern formulas
using const generics.
- Supports
no_std-friendly stack-allocated big integers. - Constant-time by default. Variable-time functions are explicitly marked as such.
- Leverage what is possible today with const generics on
stablerust. - Support
const fnas much as possible, including decoding big integers from bytes/hex and performing arithmetic operations on them, with the goal of being able to compute values at compile-time.
This crate requires Rust 1.65 at a minimum.
We may change the MSRV in the future, but it will be accompanied by a minor version bump.
