• iOS: enable sharing keychain keys between an app and its extensions (#436)
  • New keys use a bundle-id-free keychain tag, so app and extensions resolve the same key
  • Existing (legacy, bundle-id-tagged) keys keep working via a backwards-compatible fallback lookup; recreate a key to share it across extensions
  • deleteSigningKey(alias) is unchanged and now removes both new- and legacy-tagged items
