Code signing utility — validates and manages code signatures and certificates

Manages code signing operations and certificate validation for macOS applications. Accesses the Keychain to retrieve signing identities and certificates, then applies or verifies code signatures on binaries and bundles. Exposes two XPC services for system components and other tools to request signing and validation operations. Communicates with Apple's code signing infrastructure via six network endpoints to check certificate revocation status and obtain signing policies.AI
