Trait PasswordProvider 

pub trait PasswordProvider: Send + Sync {
    // Required method
    fn get_password(
        &self,
        key: Option<&Key<'_>>,
        context: &str,
    ) -> Option<Cow<'_, str>>;
}

What the library calls when it needs a passphrase to unlock a secret key.

Implementations return the password as Cow<str>; it is copied into the librnp-provided buffer before the callback returns.
