Struct holochain_types::prelude::signature::Signature [−][src]
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
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.
@todo maybe we want something like HIDDEN by default and putting the actual bytes behind a feature flag?
See https://docs.rs/subtle-encoding/0.5.1/subtle_encoding/

Trivial new type derivation. Secrets should have private interiors and be constructed directly from fixed length arrays of known length.
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.
