Struct Prk

pub struct Prk { /* private fields */ }

A HKDF PRK (pseudorandom key).

Implementations

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.

Panics

Panics if the given Prk length exceeds the limit

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

The HKDF-Expand operation.

Errors

Returns error::Unspecified if:

• len is more than 255 times the digest algorithm’s output length.

Trait Implementations

impl Clone for Prk

fn clone(&self) -> Prk

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Prk

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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

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

Converts to this type from the input type.
