Struct rfc6979::HmacDrbg

pub struct HmacDrbg<D>
where
    D: Digest + BlockSizeUser + FixedOutputReset,
{ /* private fields */ }

Internal implementation of HMAC_DRBG as described in NIST SP800-90A.

https://csrc.nist.gov/publications/detail/sp/800-90a/rev-1/final

This is a HMAC-based deterministic random bit generator used compute a deterministic ephemeral scalar k.

Implementations

impl<D> HmacDrbg<D>

where D: Digest + BlockSizeUser + FixedOutputReset,

pub fn new(entropy_input: &[u8], nonce: &[u8], additional_data: &[u8]) -> Self

Initialize HMAC_DRBG

pub fn fill_bytes(&mut self, out: &mut [u8])

Write the next HMAC_DRBG output to the given byte slice.
