TrustedManifestKeys

Struct TrustedManifestKeys 

Source
pub struct TrustedManifestKeys { /* private fields */ }
Expand description

Public keys the verifier accepts, keyed by key_id.

A manifest names the key that signed it. The verifier checks the signature against the key this set holds under that name and never against the key the manifest carries, because an attacker who can rewrite a manifest can rewrite the key beside it.

Implementations§

Source§

impl TrustedManifestKeys

Source

pub fn single(key_id: String, public_key: Vec<u8>) -> Self

A set that trusts one raw Ed25519 public key under key_id.

Source

pub fn from_pairs(pairs: impl IntoIterator<Item = (String, Vec<u8>)>) -> Self

A set built from every (key_id, public_key) pair.

An archive that spans a key rotation carries manifests signed under each key it was written with, so verifying it in one run means trusting all of them at once. A later pair wins over an earlier one naming the same key_id.

Source

pub fn get(&self, key_id: &str) -> Option<&[u8]>

The raw Ed25519 public key registered under key_id.

Source

pub fn is_empty(&self) -> bool

true when no key is trusted.

A run against an empty set still recomputes the chain and checks every object, and it counts every signed manifest as untrusted. It proves internal consistency and says nothing about who wrote the archive.

Returns self with the quirk() set to [Quirk :: Clear].

§Example
