bsa3-hash provides a Rust implementation of the hash function used in BSA files for The Elder Scrolls III: Morrowind.

Usage

Add bsa3-hash to your Cargo.toml:

[dependencies]
bsa3-hash = "^3.0.0"

Then call bsa3_hash::calculate as needed:

fn main() {
    assert_eq!(
        bsa3_hash::calculate(r"meshes\m\probe_journeyman_01.nif".as_bytes()),
        0x0002_0336, 0xBB50_0695
    );
}

Benchmarking

bsa3-hash supports benchmarking via criterion. Currently we test and benchmark against three data sets: the filename/hash lists from Morrowind.bsa, Tribunal.bsa and Bloodmoon.bsa. To run the benchmarks, simply do the following:

  • Install cargo-criterion, if you haven't already done so:
    cargo install cargo-criterion
    
  • Run cargo-criterion in the crate directory:
    cargo criterion
