starkware-crypto-rs

Rust FFI bindings for StarkWare's crypto-cpp library

Note that currently target x86_64-pc-windows-msvc is not supported. If you're building on Windows, you need to use the GNU build of Rust.

Using starknet-crypto instead

Due to a few known issues with this library:

• the underlying crypto-cpp library hasn't been updated for quite a while; and

• the library does not build on Windows with MSVC; and

• the underlying library is relatively slow in terms of performance;

you're advised to use starknet-crypto instead, which is pure-Rust implementation of the same low-level cryptography functions, with better performance and portability.
