Trait Implementations
sourceimpl AsRef<[u8]> for Hash256Bits
impl AsRef<[u8]> for Hash256Bits
sourceimpl Debug for Hash256Bits
impl Debug for Hash256Bits
The only meaningful debug information for a cryptograhpic secret is the literal bytes. Also, encodings like base64 are not constant time so debugging could open some weird side channel issue trying to be ‘human friendly’. It seems better to never try to encode secrets.

sourcefn deserialize<D>(

fn deserialize<D>(
deserializer: D

D: Deserializer<'de>,
sourceimpl From<[u8; 32]> for Hash256Bits
impl From<[u8; 32]> for Hash256Bits
Trivial new type derivation. Secrets should have private interiors and be constructed directly from fixed length arrays of known length.
sourcefn from(b: [u8; 32]) -> Hash256Bits
fn from(b: [u8; 32]) -> Hash256Bits
sourceimpl PartialEq<Hash256Bits> for Hash256Bits
impl PartialEq<Hash256Bits> for Hash256Bits
Constant time equality check. This mitigates timing attacks where a remote agent can reverse engineer data by measuring tiny changes in latency associated with optimised equality checks. More matching bytes = more latency = vulnerability. This type of attack has been successfully demonstrated over a network despite varied latencies.
