Struct ring::hkdf::Prk

source · [−]

pub struct Prk(_);

Expand description

A HKDF PRK (pseudorandom key).

Implementations

source

impl Prk

source

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.

source

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.
