# Coldcard Interface Library

`coldcard` is a library for interfacing with the [Coldcard](https://coldcard.com/) hardware wallet.

## Usage

```rust
use coldcard;
use coldcard::protocol;

// detect all connected Coldcards
let serials = coldcard::detect()?;

// open a particular one
let mut coldcard = serials[0].open()?;

// set a passphrase
coldcard.set_passphrase(protocol::Passphrase::new("secret")?)?;

// after the user confirms
let xpub = coldcard.get_passphrase_done()?;

if let Some(xpub) = xpub {
    println!("The new XPUB is: {}", xpub);
}

// secure logout
coldcard.logout()?;
```
