# Guest Attribute Dictionary Keys

Specify attributes of guest code.

## Discussion

Use these keys in the dictionary you supply as the `attributes` parameter to the [`SecHostCreateGuest`](/documentation/Security/SecHostCreateGuest), [`SecHostSetGuestStatus`](/documentation/Security/SecHostSetGuestStatus), and [`SecCodeCopyGuestWithAttributes(_:_:_:_:)`](/documentation/Security/SecCodeCopyGuestWithAttributes(_:_:_:_:)) functions.

## Topics

### Constants

[`let kSecGuestAttributeArchitecture: CFString`](/documentation/Security/kSecGuestAttributeArchitecture)

A key whose value is a number representing the CPU type under which the guest code is designed to run.

[`let kSecGuestAttributeAudit: CFString`](/documentation/Security/kSecGuestAttributeAudit)

[`let kSecGuestAttributeCanonical: CFString`](/documentation/Security/kSecGuestAttributeCanonical)

A key whose value is the guest code object for that guest.

[`let kSecGuestAttributeDynamicCode: CFString`](/documentation/Security/kSecGuestAttributeDynamicCode)

[`let kSecGuestAttributeDynamicCodeInfoPlist: CFString`](/documentation/Security/kSecGuestAttributeDynamicCodeInfoPlist)

[`let kSecGuestAttributeHash: CFString`](/documentation/Security/kSecGuestAttributeHash)

A key whose value is a data object containing the SHA-1 hash of the code directory.
