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.
Goals
- No heap allocations.
no_std
-friendly. - Constant-time by default. Variable-time functions are explicitly marked as such.
- Leverage what is possible today with const generics on
stable
rust. - Support
const fn
as 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.
Minimum Supported Rust Version
Rust 1.51 at a minimum.
