Okm

rama::crypto::dep::aws_lc_rs::hkdf

Struct Okm

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

Available on crate feature crypto only.

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>

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.
