zCloak Keychain is the cryptographic foundation of the system.
It is responsible for:
Key generation
Key storage
Signing operations
Recovery and rotation
Keychain exists to make cryptographic identity usable by non-experts.
Trust in ATP depends on keys. But user-managed keys are fragile:
loss and theft are common
UX is too complex for mainstream adoption
operational burden is high for enterprises
Keychain makes cryptography practical by making it invisible.
Social login (email, Apple, etc.) as identity entry point
Passkey / biometrics for authorization
Multi-path recovery by linking multiple credentials
User experience remains familiar: “Sign in with Apple”, then sign actions with FaceID.
For enterprises and AI agents, Keychain supports:
Local key generation
TEE-based protection
Enterprise SSO integration
Key lifecycle management and revocation
Keychain does not:
Interpret data
Publish events on its own
Act as a custodian of user intent
It performs only cryptographic operations, nothing else.
Keychain powers AI-ID. Users typically do not interact with it directly, but it is foundational to frictionless adoption.
