Crate hasherkawpow_sys 

hasherkawpow-sys

Low-level Rust bindings for KawPow hashing and verification.

This crate provides two functions:

• hash_kawpow — compute a KawPow hash from a header hash, nonce, and block height.
• verify_kawpow — verify a previously computed KawPow hash.

These functions wrap FFI calls to native implementations via unsafe code, but expose a safe Rust API with fixed-size arrays.

Upstream Source

The underlying C source code is from MintPond’s hasher-kawpow library, which itself adapts most of its native code from the Ravencoin project.

Example

use hasherkawpow_sys::{hash_kawpow, verify_kawpow};

let header_hash = [0u8; 32];
let nonce: u64 = 42;
let block_height = 100;

// Compute a hash
let (mix, hash) = hash_kawpow(&header_hash, &nonce, block_height);

// Verify the hash
assert!(verify_kawpow(&header_hash, &nonce, block_height, &mix, &hash));

Functions

hash_kawpow

Computes a KawPow hash.

verify_kawpow

Verifies a KawPow hash result.
