axum-password-worker

A module providing a password hashing and verification worker.

This module contains the PasswordWorker struct, which manages hashing and verification operations using a combination of a rayon thread pool and crossbeam-channel to efficiently handle these operations asynchronously. It also makes use of a tokio::sync::oneshot channel but does not require the tokio runtime to be present.

The methods will not block the async runtime. All await operations do not block. They use non-blocking channel implementations to send and receive passwords and hashes to the rayon thread pool.

PasswordWorker is Send + Sync + Clone, and contains no lifetimes. The Clone implementation is a shallow copy that "points" to the same thread pool. It can be used as shared state without an Arc. All methods take &self so a Mutex is also not necessary.

Add as Dependency

```bash cargo add axum-password-worker

OR if you want to also add argon2 support

cargo add axum-password-worker -F rust-argon2 ```

Example

```rust use axumpasswordworker::{BcryptConfig, PasswordWorker};

[tokio::main]

async fn main() -> Result<(), Box> { let password = "hunter2"; let cost = 12; // bcrypt cost value let maxthreads = 4; // rayon thread pool max threads let passwordworker = PasswordWorker::newbcrypt(maxthreads)?;

let hashed_password = password_worker.hash(password, BcryptConfig { cost }).await?;
println!("Hashed password: {:?}", hashed_password);

let is_valid = password_worker.verify(password, hashed_password).await?;
println!("Verification result: {:?}", is_valid);

Ok(())

} ```

Available feature flags

There are some implementations included in the library. Each is tied to optional dependency features. * bcrypt - (default) (dependency), exports the Bcrypt and BcryptConfig types. * rust-argon2 - (dependency), exports the Argon2id and Argon2idConfig types.
