Trait engine::vault::BoxProvider[−][src]

pub trait BoxProvider: Sized + Ord + PartialOrd {
    fn box_key_len() -> usize;

    fn box_overhead() -> usize;

    fn box_seal(key: &Key<Self>, ad: &[u8], data: &[u8]) -> Result<Vec<u8>>;

    fn box_open(key: &Key<Self>, ad: &[u8], data: &[u8]) -> Result<Vec<u8>>;

    fn random_buf(buf: &mut [u8]) -> Result<()>;

    fn random_vec(len: usize) -> Result<Vec<u8>> { ... }
}

A provider interface between the vault and a crypto box. See libsodium’s secretbox for an example.

Required methods

fn box_key_len() -> usize[src]

function for the key length of the crypto box

fn box_overhead() -> usize[src]

gets the crypto box’s overhead

fn box_seal(key: &Key<Self>, ad: &[u8], data: &[u8]) -> Result<Vec<u8>>[src]

seals some data into the crypto box using the key and the ad

fn box_open(key: &Key<Self>, ad: &[u8], data: &[u8]) -> Result<Vec<u8>>[src]

opens a crypto box to get data using the key and the ad.

fn random_buf(buf: &mut [u8]) -> Result<()>[src]

fills a buffer buf with secure random bytes.
