hash4lf
Fast hashing for large files
A rewritten version of imohash in Rust.
Usage
Add this to your Cargo.toml:
[dependencies]
hash4lf = "0.1"
then
use hash4lf::Hasher;
// Creates a new hasher using default sample parameters
let hasher = Hasher::new();
//or creates with custom sample parameters
let hasher = Hasher::with_sample_size_and_threshold(3, 45);
// Hashes a byte slice
let hash_value = hasher.sum("hello".as_bytes()).unwrap();
// Hashes a file
let hash_value = hasher.sum_file("samples/system.evtx").unwrap();
Algorithm
Consult the documentation for more information.
Misuses
Because hash4lf only reads a small portion of a file's data, it is not suitable for:
- file verification or integrity monitoring
- cases where fixed-size files are manipulated
- anything cryptographic
