identity-auth

Authentication: users, sessions, passwords, API keys

What it is for

Authentication library crates for Rust applications.

This crate provides:

• User model (links to Person from identity-parties)
• Session management (compatible with tower-sessions)
• Password hashing with Argon2
• Login attempt tracking for rate limiting
• API key authentication for service accounts

# Example

use identity_auth::{User, Password, Session};

// Create a user
let user = User::new("john@example.com")
.with_password("secure_password")?;

// Verify password
assert!(user.verify_password("secure_password")?);

// Create a session
let session = Session::new(user.id);

Capabilities

No public items.

How to use it

From `examples/gen_hash.rs`:

use identity_auth::Password;
use std::env;

fn main() {
    let password = env::args()
        .nth(1)
        .unwrap_or_else(|| "changeme123".to_string());
    match Password::hash(&password) {
        Ok(hash) => println!("{}", hash),
        Err(e) => eprintln!("Error: {}", e),
    }
}

Module structure

No public modules: the crate root is its whole surface.

Public surface

No public items.

Re-exports. Exported here, defined elsewhere.

Boundary

Reaches into foundation.

Shares tier identity with 7 other crates: identity-identifiers, identity-impersonation, identity-parties, identity-party-places, identity-rbac, identity-tenant, identity-user-prefs.

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._

Feature flags

No Cargo features are defined: every capability is unconditional, so no consumer can receive a half-wired crate.

Targets

Error model

No public error type was detected: no public item declares a type named *Error, and no public signature returns one.

Operational characteristics

No unsafe block, unsafe fn, unsafe impl or unsafe trait was found by the parser anywhere in this crate's source.

Configuration

No environment variable is read with a literal name anywhere in this crate. A variable whose key is computed at run time cannot be listed here, and is not claimed to be absent.

Related capabilities

4 workspace crates depend on this one: application-auth, application-dlp, application-party-api, application-rbac.
