# lib2fas.rs
**`lib2fas`** is an unofficial implementation of the [2fas](https://2fas.com/) platform for Rust, providing tools for
managing and interacting with two-factor authentication (2FA) services as a library.
## Installation
Add `lib2fas` to your `Cargo.toml`:
```shell
cargo add lib2fas
```
Or add it manually with a specific version:
```toml
# Cargo.toml
[dependencies]
lib2fas = "x.y.z"
```
## Usage
### Loading and Querying 2FA Services
```rust
use lib2fas::load_services;
#[tokio::main]
async fn main() {
let maybe_storage = load_services("path/to/services.2fas", Some("your-passphrase")).await;
match maybe_storage {
Ok(storage) => {
println!("Loaded {} services", storage.len());
if let Some(service) = storage.find_first("example-service") {
println!("Found service: {}", service.name);
if let Some(otp) = service.totp() {
println!("Current OTP: {}", otp);
}
if let Some(next_otp) = service.totp_next() {
println!("Next OTP: {}", next_otp);
}
if let Some(current_otp_u32) = service.totp_u32() {
println!("Current OTP (as number): {}", current_otp_u32);
}
} else {
println!("Service not found.");
}
}
Err(err) => {
eprintln!("Failed to load services: {}", err);
}
}
}
```
