Okm

rama::crypto::dep::ring::hkdf

Struct Okm

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

Available on crate features crypto and ring and std 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>
where L: KeyType,

pub fn len(&self) -> &L

The OkmLength given to Prk::expand().

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

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

Fails if (and only if) the requested output length is larger than 255 times the size of the digest algorithm’s output. (This is the limit imposed by the HKDF specification due to the way HKDF’s counter is constructed.)
