Code signing utility — validates and manages cryptographic signatures on executables

Validates code signatures on macOS binaries and frameworks, verifying cryptographic integrity and entitlements. Accesses the Keychain and certificate store to retrieve signing identities and validate certificate chains. Communicates with Apple's code signing infrastructure via network endpoints to check revocation status and obtain timestamp attestations. Exposes an XPC service for other processes to request signature validation and code signing operations. Operates with direct hardware access for secure cryptographic operations.AI
