libbruteforce - A Rust library to brute force hashes with multiple threads

This library spawns a thread for each cpu on your system to brute force a password/hash. It offers built-in support for MD5, SHA1, and SHA256, but you can also provide your own hashing function as a parameter.

You can specify your own alphabet to limit search space or use the internally hard-coded symbols (the most common chars).

JUST FOR FUN!

I did this project just for fun to learn new things. Please don't use it to do any harm to someone's privacy!

Maximum Performance

If you use this in a project: To let the Rust compiler produce a binary with maximum performance, follow the steps here: - https://www.reddit.com/r/rust/comments/lyck1u/compiling_for_maximum_performance/ - https://deterministic.space/high-performance-rust.html

MSRV

1.56.1

Works On

Linux, MacOS, Windows (targets with Rusts standard library)

Performance Hint

Always execute binaries that use this library in release mode, e.g. cargo run --bin bench --release. Otherwise, the performance is really poor. For maximum Rust performance, see: https://deterministic.space/high-performance-rust.html

Example usage

```rust use libbruteforce::hashfncs::sha256hashing; use libbruteforce::BasicCrackParameter; use libbruteforce::{symbols, CrackParameter, TargetHashInput}; use simple_logger::SimpleLogger;

/// Minimal example. fn main() { // to get information about trace! logs (like progress) on the console SimpleLogger::new().withutctimestamps().init().unwrap();

let alphabet = symbols::Builder::new()
    .with_lc_letters()
    .with_common_special_chars()
    .build();

// sha256("a+c")
let sha256_hash = "3d7edde33628331676b39e19a3f2bdb3c583960ad8d865351a32e2ace7d8e02d";

// the actual cracking
let res = libbruteforce::crack(CrackParameter::new(
    BasicCrackParameter::new(alphabet, 3, 0, true),
    sha256_hashing(TargetHashInput::HashAsStr(sha256_hash)),
));

if let Some(solution) = res.solution() {
    println!("Password is: {}", solution);
    println!("Took {:.3}s", res.duration_in_seconds());
}

} ```
