Struct ring::hkdf::Prk

pub struct Prk(_);

A HKDF PRK (pseudorandom key).

Methods

impl Prk

pub fn new_less_safe(algorithm: Algorithm, value: &[u8]) -> Self

Construct a new Prk directly with the given value.

Usually one can avoid using this. It is useful when the application intentionally wants to leak the PRK secret, e.g. to implement SSLKEYLOGFILE functionality.

pub fn expand<'a, L: KeyType>(
    &'a self,
    info: &'a [&'a [u8]],
    len: L
) -> Result<Okm<'a, L>, Unspecified>

The HKDF-Expand operation.

Fails if (and only if) len is too large.

Trait Implementations

impl<'_> From<Okm<'_, Algorithm>> for Prk

fn from(okm: Okm<Algorithm>) -> Self

Performs the conversion.

impl Clone for Prk

fn clone(&self) -> Prk

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
