Prk

bssl_crypto::hkdf

Struct Prk 

Source 
pub struct Prk { /* private fields */ }
Expand description

A pseudo-random key, an intermediate value in the HKDF computation.

Implementations§

Source§

impl Prk

Source

pub fn new<MD: Algorithm>(prk_bytes: &[u8]) -> Option<Self>

Creates a Prk from bytes.

Source

pub fn as_bytes(&self) -> &[u8]

Returns the bytes of the pseudorandom key.

Source

pub fn expand<const N: usize>(&self, info: &[u8]) -> [u8; N]

Derive key material for the given info parameter. Attempting to derive more than 255 bytes is a compile-time error, see expand_into for longer outputs.

Source

pub fn expand_into(&self, info: &[u8], out: &mut [u8]) -> Result<(), TooLong>

Derive key material from the given info parameter. Attempting to derive more than the HKDF’s MAX_OUTPUT_LEN bytes is a run-time error.
