Some of these attributes are mathematical -- for example, a DSA key cannot encrypt. Others are key-level policy issues -- for example, it is good cryptographic hygiene to use an RSA key either for encryption or signing but not both. Compare these to the certificate-level policy values in SecPolicy.h. kSecClassIdentity item attributes: Since an identity is the combination of a private key and a certificate, this class shares attributes of both kSecClassKey and kSecClassCertificate. @constant kSecAttrAccessible Specifies a dictionary key whose value indicates when your application needs access to an item's data. You should choose the most restrictive option that meets your application's needs to allow the system to protect that item in the best way possible. See the "kSecAttrAccessible Value Constants" section for a list of values which can be specified. IMPORTANT: This attribute is currently not supported for OS X keychain items, unless the kSecAttrSynchronizable attribute is also present. If both attributes are specified on either OS X or iOS, the value for the kSecAttrAccessible key may only be one whose name does not end with "ThisDeviceOnly", as those cannot sync to another device. @constant kSecAttrAccessControl Specifies a dictionary key whose value is SecAccessControl instance which contains access control conditions for item. IMPORTANT: This attribute is mutually exclusive with kSecAttrAccess attribute. @constant kSecAttrAccess Specifies a dictionary key whose value is a SecAccessRef describing the access control settings for this item. This key is available on OS X only. @constant kSecAttrAccessGroup Specifies a dictionary key whose value is a CFStringRef indicating which access group a item is in. The access groups that a particular application has membership in are determined by two entitlements for that application. The application-identifier entitlement contains the application's single access group, unless there is a keychain-access-groups entitlement present. The latter has as its value a list of access groups; the first item in this list is the default access group. Unless a specific access group is provided as the value of kSecAttrAccessGroup when SecItemAdd is called, new items are created in the application's default access group. Specifying this attribute in SecItemCopyMatching, SecItemUpdate, or SecItemDelete calls limits the search to the specified access group (of which the calling application must be a member to obtain matching results.) To share keychain items between multiple applications, each application must have a common group listed in its keychain-access-groups entitlement, and each must specify this shared access group name as the value for the kSecAttrAccessGroup key in the dictionary passed to SecItem functions. @constant kSecAttrSynchronizable Specifies a dictionary key whose value is a CFBooleanRef indicating whether the item in question can be synchronized. To add a new item which can be synced to other devices, or to obtain synchronizable results from a query, supply this key with a value of kCFBooleanTrue. If the key is not supplied, or has a value of kCFBooleanFalse, then no synchronizable items will be added or returned. A predefined value, kSecAttrSynchronizableAny, may be provided instead of kCFBooleanTrue if both synchronizable and non-synchronizable results are desired. IMPORTANT: Specifying the kSecAttrSynchronizable key has several caveats: - Updating or deleting items using the kSecAttrSynchronizable key will affect all copies of the item, not just the one on your local device. Be sure that it makes sense to use the same password on all devices before deciding to make a password synchronizable. - Only password items can currently be synchronized. Keychain syncing is not supported for certificates or cryptographic keys. - Items stored or obtained using the kSecAttrSynchronizable key cannot specify SecAccessRef-based access control with kSecAttrAccess. If a password is intended to be shared between multiple applications, the kSecAttrAccessGroup key must be specified, and each application using this password must have a 'keychain-access-groups' entitlement with the specified access group value. - Items stored or obtained using the kSecAttrSynchronizable key may not also specify a kSecAttrAccessible value which is incompatible with syncing (namely, those whose names end with "ThisDeviceOnly".) - Items stored or obtained using the kSecAttrSynchronizable key cannot be specified by reference. You must pass kSecReturnAttributes and/or kSecReturnData to retrieve results; kSecReturnRef is currently not supported for synchronizable items. - Persistent references to synchronizable items should be avoided; while they may work locally, they cannot be moved between devices, and may not resolve if the item is modified on some other device. - When specifying a query that uses the kSecAttrSynchronizable key, search keys are limited to the item's class and attributes. The only search constant which may be used is kSecMatchLimit; other constants using the kSecMatch prefix are not supported at this time. @constant kSecAttrSynchronizableAny Specifies that both synchronizable and non-synchronizable results should be returned from this query. This may be used as a value for the kSecAttrSynchronizable dictionary key in a call to SecItemCopyMatching, SecItemUpdate, or SecItemDelete. @constant kSecAttrCreationDate (read-only) Specifies a dictionary key whose value is the item's creation date. You use this key to get a value of type CFDateRef that represents the date the item was created. @constant kSecAttrModificationDate (read-only) Specifies a dictionary key whose value is the item's modification date. You use this key to get a value of type CFDateRef that represents the last time the item was updated. @constant kSecAttrDescription Specifies a dictionary key whose value is the item's description attribute. You use this key to set or get a value of type CFStringRef that represents a user-visible string describing this particular kind of item (e.g., "disk image password"). @constant kSecAttrComment Specifies a dictionary key whose value is the item's comment attribute. You use this key to set or get a value of type CFStringRef containing the user-editable comment for this item. @constant kSecAttrCreator Specifies a dictionary key whose value is the item's creator attribute. You use this key to set or get a value of type CFNumberRef that represents the item's creator. This number is the unsigned integer representation of a four-character code (e.g., 'aCrt'). @constant kSecAttrType Specifies a dictionary key whose value is the item's type attribute. You use this key to set or get a value of type CFNumberRef that represents the item's type. This number is the unsigned integer representation of a four-character code (e.g., 'aTyp'). @constant kSecAttrLabel Specifies a dictionary key whose value is the item's label attribute. You use this key to set or get a value of type CFStringRef containing the user-visible label for this item. @constant kSecAttrIsInvisible Specifies a dictionary key whose value is the item's invisible attribute. You use this key to set or get a value of type CFBooleanRef that indicates whether the item is invisible (i.e., should not be displayed.) @constant kSecAttrIsNegative Specifies a dictionary key whose value is the item's negative attribute. You use this key to set or get a value of type CFBooleanRef that indicates whether there is a valid password associated with this keychain item. This is useful if your application doesn't want a password for some particular service to be stored in the keychain, but prefers that it always be entered by the user. @constant kSecAttrAccount Specifies a dictionary key whose value is the item's account attribute. You use this key to set or get a CFStringRef that contains an account name. (Items of class kSecClassGenericPassword, kSecClassInternetPassword have this attribute.) @constant kSecAttrService Specifies a dictionary key whose value is the item's service attribute. You use this key to set or get a CFStringRef that represents the service associated with this item. (Items of class kSecClassGenericPassword have this attribute.) @constant kSecAttrGeneric Specifies a dictionary key whose value is the item's generic attribute. You use this key to set or get a value of CFDataRef that contains a user-defined attribute. (Items of class kSecClassGenericPassword have this attribute.) @constant kSecAttrSecurityDomain Specifies a dictionary key whose value is the item's security domain attribute. You use this key to set or get a CFStringRef value that represents the Internet security domain. (Items of class kSecClassInternetPassword have this attribute.) @constant kSecAttrServer Specifies a dictionary key whose value is the item's server attribute. You use this key to set or get a value of type CFStringRef that contains the server's domain name or IP address. (Items of class kSecClassInternetPassword have this attribute.) @constant kSecAttrProtocol Specifies a dictionary key whose value is the item's protocol attribute. You use this key to set or get a value of type CFNumberRef that denotes the protocol for this item (see the SecProtocolType enum in SecKeychainItem.h). (Items of class kSecClassInternetPassword have this attribute.) @constant kSecAttrAuthenticationType Specifies a dictionary key whose value is the item's authentication type attribute. You use this key to set or get a value of type CFNumberRef that denotes the authentication scheme for this item (see the kSecAttrAuthenticationType value constants below). @constant kSecAttrPort Specifies a dictionary key whose value is the item's port attribute. You use this key to set or get a CFNumberRef value that represents an Internet port number. (Items of class kSecClassInternetPassword have this attribute.) @constant kSecAttrPath Specifies a dictionary key whose value is the item's path attribute, typically this is the path component of the URL. You use this key to set or get a CFStringRef value that represents a path. (Items of class kSecClassInternetPassword have this attribute.) @constant kSecAttrSubject (read-only) Specifies a dictionary key whose value is the item's subject. You use this key to get a value of type CFDataRef that contains the X.500 subject name of a certificate. (Items of class kSecClassCertificate have this attribute.) @constant kSecAttrIssuer (read-only) Specifies a dictionary key whose value is the item's issuer. You use this key to get a value of type CFDataRef that contains the X.500 issuer name of a certificate. (Items of class kSecClassCertificate have this attribute.) @constant kSecAttrSerialNumber (read-only) Specifies a dictionary key whose value is the item's serial number. You use this key to get a value of type CFDataRef that contains the serial number data of a certificate. (Items of class kSecClassCertificate have this attribute.) @constant kSecAttrSubjectKeyID (read-only) Specifies a dictionary key whose value is the item's subject key ID. You use this key to get a value of type CFDataRef that contains the subject key ID of a certificate. (Items of class kSecClassCertificate have this attribute.) @constant kSecAttrPublicKeyHash (read-only) Specifies a dictionary key whose value is the item's public key hash. You use this key to get a value of type CFDataRef that contains the hash of a certificate's public key. (Items of class kSecClassCertificate have this attribute.) @constant kSecAttrCertificateType (read-only) Specifies a dictionary key whose value is the item's certificate type. You use this key to get a value of type CFNumberRef that denotes the certificate type (On iOS, currently the value of this attribute must be equal to the version of the X509 certificate. So, 1 for v1, 2 for v2, and 3 for v3 certificates). (On OSX, see the CSSM_CERT_TYPE enum in cssmtype.h). Only items of class kSecClassCertificate have this attribute. @constant kSecAttrCertificateEncoding (read-only) Specifies a dictionary key whose value is the item's certificate encoding. You use this key to get a value of type CFNumberRef that denotes the certificate encoding (On iOS, currently only the value 3 meaning kSecAttrCertificateEncodingDER is supported). On OSX, see the CSSM_CERT_ENCODING enum in cssmtype.h. Only items of class kSecClassCertificate have this attribute. @constant kSecAttrKeyClass (read only) Specifies a dictionary key whose value is one of kSecAttrKeyClassPublic, kSecAttrKeyClassPrivate or kSecAttrKeyClassSymmetric. @constant kSecAttrApplicationLabel Specifies a dictionary key whose value is the key's application label attribute. This is different from the kSecAttrLabel (which is intended to be human-readable). This attribute is used to look up a key programmatically; in particular, for keys of class kSecAttrKeyClassPublic and kSecAttrKeyClassPrivate, the value of this attribute is the hash of the public key. This item is a type of CFDataRef. Legacy keys may contain a UUID in this field as a CFStringRef. @constant kSecAttrIsPermanent Specifies a dictionary key whose value is a CFBooleanRef indicating whether the key in question will be stored permanently. @constant kSecAttrIsSensitive Specifies a dictionary key whose value is a CFBooleanRef indicating that the key in question can only be exported in a wrapped (encrypted) format. OS X only. @constant kSecAttrIsExtractable Specifies a dictionary key whose value is a CFBooleanRef indicating whether the key in question can be exported from its keychain container. OS X only. @constant kSecAttrApplicationTag Specifies a dictionary key whose value is a CFDataRef containing private tag data. @constant kSecAttrKeyType Specifies a dictionary key whose value is a CFNumberRef indicating the algorithm associated with this key (On iOS, currently only the value 42 is supported, alternatively you can use kSecAttrKeyTypeRSA). (On OSX, see the CSSM_ALGORITHMS enum in cssmtype.h). @constant kSecAttrPRF Specifies a dictionary key whose value is the PRF (pseudo-random function) for this key (see "kSecAttrPRF Value Constants".)

This value is part of the primary key of each item, and can be used to help distiguish Sync Views when defining their queries. iOS and sychronizable items only. @constant kSecAttrTokenID Specifies a dictionary key whose presence indicates that item is backed by external token. Value of this attribute is CFStringRef uniquely identifying containing token. When this attribute is not present, item is stored in internal keychain database. Note that once item is created, this attribute cannot be changed - in other words it is not possible to migrate existing items to, from or between tokens. Currently the only available value for this attribute is kSecAttrTokenIDSecureEnclave, which indicates that item (private key) is backed by device's Secure Enclave. iOS only. */ extern const CFStringRef kSecAttrAccessible API_AVAILABLE(macos(10.9), ios(4.0)); extern const CFStringRef kSecAttrAccess API_AVAILABLE(macos(10.7), ios(NA), bridgeos(NA)); extern const CFStringRef kSecAttrAccessControl API_AVAILABLE(macos(10.10), ios(8.0)); extern const CFStringRef kSecAttrAccessGroup API_AVAILABLE(macos(10.9), ios(3.0)); extern const CFStringRef kSecAttrSynchronizable API_AVAILABLE(macos(10.9), ios(7.0)); extern const CFStringRef kSecAttrSynchronizableAny API_AVAILABLE(macos(10.9), ios(7.0)); extern const CFStringRef kSecAttrCreationDate API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrModificationDate API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrDescription API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrComment API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrCreator API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrType API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrLabel API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrIsInvisible API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrIsNegative API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrAccount API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrService API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrGeneric API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrSecurityDomain API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrServer API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrProtocol API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrAuthenticationType API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrPort API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrPath API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrSubject API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrIssuer API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrSerialNumber API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrSubjectKeyID API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrPublicKeyHash API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrCertificateType API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrCertificateEncoding API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrKeyClass API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrApplicationLabel API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrIsPermanent API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrIsSensitive API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrIsExtractable API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrApplicationTag API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrKeyType API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrPRF API_AVAILABLE(macos(10.7), ios(NA), bridgeos(NA)); extern const CFStringRef kSecAttrSalt API_AVAILABLE(macos(10.7), ios(NA), bridgeos(NA)); extern const CFStringRef kSecAttrRounds API_AVAILABLE(macos(10.7), ios(NA), bridgeos(NA)); extern const CFStringRef kSecAttrKeySizeInBits API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrEffectiveKeySize API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrCanEncrypt API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrCanDecrypt API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrCanDerive API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrCanSign API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrCanVerify API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrCanWrap API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrCanUnwrap API_AVAILABLE(macos(10.6), ios(2.0)); extern const CFStringRef kSecAttrSyncViewHint API_AVAILABLE(macos(10.11), ios(9.0)); extern const CFStringRef kSecAttrTokenID API_AVAILABLE(macos(10.12), ios(9.0)); extern const CFStringRef kSecAttrPersistantReference API_AVAILABLE(macos(10.13), ios(11.0), tvos(11.0), watchos(4.0)); extern const CFStringRef kSecAttrPersistentReference API_AVAILABLE(macos(10.13), ios(11.0), tvos(11.0), watchos(4.0)); /*! @enum kSecAttrAccessible Value Constants @discussion Predefined item attribute constants used to get or set values in a dictionary.
