Struct ring::hkdf::Okm[−][src]

pub struct Okm<'a, L: KeyType> { /* fields omitted */ }
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: KeyType> Okm<'_, L>[src]

pub fn len(&self) -> &L[src]

The OkmLength given to Prk::expand().

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

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.)
