Security certificate validator — verifies code signatures and keychain credentials

Validates code signatures, certificates, and keychain items for macOS security enforcement. Communicates with hardware and driver systems to perform cryptographic operations and access stored credentials. Exposes three XPC services for other system components to request verification of code signatures and certificate chains. Collects telemetry about validation operations and connects to multiple network endpoints, likely for certificate revocation checking and trust anchor updates.AI
