I am configuring the Info.plist file for a new macOS CryptoTokenKit extension. I added com.apple.ctk-tokens as the extension point identifier and set Principal Class to my driver class. What exact attribute key must be used to define the driver class name?
| Checked | Without skill | With skill |
|---|---|---|
| Specifies com.apple.ctk.driver-class in NSExtensionAttributes | Missed | Passed |
| Sets the value to the fully qualified driver class name using module name variable | Missed | Passed |
The instructions your model reads when the skill loads.
Use CryptoTokenKit for token driver extensions, smart-card communication, token sessions, token-backed keychain integration, and certificate-based authentication in Swift 6.3 apps.
Platform availability: CryptoTokenKit classes are available across Apple
platforms, but capability depends on extension point, entitlement, hardware, and
OS version. The smart-card app extension flow for login/keychain unlock is macOS.
TKSmartCardSlotManager.default is optional and returns nil unless smart-card
access is enabled. iOS/iPadOS 26+ add NFC smart-card slots and registration.
CryptoTokenKit bridges hardware security tokens (smart cards, USB tokens) with authentication and keychain services. The framework has three main usage modes:
Smart-card token extensions -- macOS app extensions that make a hardware token's cryptographic items available to system login and keychain unlock. The driver handles token lifecycle, session management, and cryptographic operations.
Client-side token access -- Apps query the keychain for items backed by tokens. CryptoTokenKit exposes token items as standard keychain entries when a token is present.
