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.

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

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
