Expand description
The raw bytes of a signature. The equality is not different, it’s just constant time, so we can derive a hash. For an actually secure thing we wouldn’t want to just assume a safe default hashing But that is not what clippy is complaining about here.

Trait Implementations
sourceimpl AsRef<Signature> for VerifySignature
impl AsRef<Signature> for VerifySignature
sourceimpl Debug for Signature
impl Debug for Signature
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.
Note that when using this crate with feature “subtle-encoding”, a hex representation will be used.
@todo maybe we want something like HIDDEN by default and putting the actual bytes behind a feature flag?

sourceimpl From<[u8; 64]> for Signature
impl From<[u8; 64]> for Signature
Trivial new type derivation. Secrets should have private interiors and be constructed directly from fixed length arrays of known length.
sourceimpl Ord for Signature
impl Ord for Signature
sourceimpl PartialEq<Signature> for Signature
impl PartialEq<Signature> for Signature
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.
