Verify package signatures from npm registries

Installation

pnpm add @pnpm/deps.security.signatures

Signature Verification

verifySignatures() verifies ECDSA registry signatures for installed package versions. It fetches public keys from each package's registry at /-/npm/v1/keys, fetches full package metadata, and verifies each signature over ${name}@${version}:${integrity}.

Registries that do not expose signing keys are skipped. Sigstore provenance attestations are not yet verified by this package; they are tracked as future scope.
