Trait Rotation

pub trait Rotation {
    // Required method
    fn rotate(&mut self) -> Result<(), BwError>;
}

The Rotation trait encapsulates the best practice of rotating cryptographic or sensitive materials, minimizing the potential impact of key compromise or algorithmic predictions.

Secure systems often implement rotation to limit the utility of compromised keys and to periodically refresh cryptographic materials, ensuring persistent protection against evolving threats.

Example

let key = EdDsaKey::generate().expect("Key generation failed");
let mut expiring_key = AutoExpiring::new(Duration::seconds(10), key).unwrap();
expiring_key.rotate().expect("Key generation failed");

Good Practices

Implement the Rotation trait for entities in your application where periodical change or refreshment is vital for sustaining security, especially for cryptographic keys, tokens, or salts.

Required Methods

fn rotate(&mut self) -> Result<(), BwError>
