axum-password-worker

A module providing a password hashing and verification worker.

This module contains the PasswordWorker struct, which manages bcrypt hashing and verification operations using a combination of a rayon thread pool and crossbeam-channel to efficiently handle these operations asynchronously.

The methods will not block the tokio 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, so it can be used as axum state without an Arc.

Example

```rust

#[tokio::main]

async fn main() -> Result<(), Box> {

use axumpasswordworker::{BcryptConfig, PasswordWorker};

let password = "hunter2"; let cost = 12; // bcrypt cost value let maxthreads = 4; // rayon thread pool max threads let passwordworker = PasswordWorker::newbcrypt(maxthreads)?;

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

let isvalid = passwordworker.verify(password, hashedpassword).await?; println!("Verification result: {:?}", isvalid);

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.
