Struct Okm

pub struct Okm<'a, L>where
    L: KeyType,
{ /* private fields */ }

Expand description

An HKDF OKM (Output Keying Material)

Intentionally not Clone or Copy as an OKM is generally only safe to use once.

Implementations§

impl<L> Okm<'_, L>
where L: KeyType,

pub fn len(&self) -> &L

pub fn fill(self, out: &mut [u8]) -> Result<(), Unspecified>

Fills out with the output of the HKDF-Expand operation for the given inputs.

§Errors

error::Unspecified if the requested output length differs from the length specified by L: KeyType.
