fix: skip registry key check for keyless (Sigstore/Fulcio) attestations#454
Conversation
Attestations signed with keyless Sigstore/Fulcio have no keyid and embed the signing certificate directly in the bundle. The existing guard unconditionally required matching registry keys, causing EMISSINGSIGNATUREKEY for registries that only use keyless signing. Only throw when there are keyed attestations that can't be matched.

This seems reasonable. No need to throw an error about missing keys if there are no attestations which require keys for verification.

npm audit signatures fails when a registry only uses keyless (Sigstore/Fulcio) attestations and doesn't provide registry signing keys. The[ auditedWithKeysCount guard in verify-signatures.js ](https://github.com/npm/cli/blob/latest/lib/utils/verify-signatures.js#L48) treats any registry without keys as unsupported, even though keyless attestations don't need registry keys at all -- the signing certificate is embedded directly in the bundle and verified through Sigstore's TUF root of trust. This updates the check to also accept verified keyless attestations as a valid audit result, so registries that exclusively use Fulcio-based signing (like Chainguard) work correctly with npm audit signatures. Before this change: npm error found no dependencies to audit that were installed from a supported registry After: audited 1 package in 1s 1 package has a verified attestation This change works together with the corresponding pacote fixes ([pacote/pull/454](npm/pacote#454)) ([pacote/pull/452](npm/pacote#452)) which allows keyless attestation bundles to pass the registry key matching check.

Attestations signed with keyless Sigstore/Fulcio have no keyid and
embed the signing certificate directly in the bundle. The existing
guard unconditionally required matching registry keys, causing
EMISSINGSIGNATUREKEY for registries that only use keyless signing.
Only throw when there are keyed attestations that can't be matched.
