Struct holochain_types::prelude::capability::CapSecret
[−]pub struct CapSecret(_);
Expand description
A CapSecret is used by a caller to prove to a callee access to a committed CapGrant.
It is a random, unique identifier for the capability, which is shared by the grantor to allow access to others. The grantor can optionally further restrict usage of the secret to specific agents.
@todo enforce that secrets are unique across all grants in a chain.

fn arbitrary(u: &mut Unstructured<'a>) -> Result<CapSecret, Error>
fn arbitrary(u: &mut Unstructured<'a>) -> Result<CapSecret, Error>
Generate an arbitrary value of Self
from the given unstructured data. Read more

Generate an arbitrary value of Self
from the entirety of the given unstructured data. Read more
impl Debug for CapSecret
impl Debug for CapSecret
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?

fn deserialize<D>(
deserializer: D

D: Deserializer<'de>,
fn deserialize<D>(
deserializer: D
) -> Result<CapSecret, <D as Deserializer<'de>>::Error> where
D: Deserializer<'de>,
Deserialize this value from the given Serde deserializer. Read more
impl From<[u8; 64]> for CapSecret
impl From<[u8; 64]> for CapSecret
Trivial new type derivation. Secrets should have private interiors and be constructed directly from fixed length arrays of known length.
impl From<CapSecret> for CapAccess
impl From<CapSecret> for CapAccess
Implements secret.into() shorthand for CapAccess::Transferable(secret)
impl PartialEq<CapSecret> for CapSecret
impl PartialEq<CapSecret> for CapSecret
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.
