Keychain Services

Keychain Services is a programming interface that enables you to find, add, modify, and delete keychain items.


If you want to look at some code that uses this API, you can find the source code for the security command-line tool in the Security​Tool project on


Using Keychain Item Search Dictionaries

For this interface, keychain items are found or defined by a CFDictionary of key-value pairs. Each key in the dictionary identifies one attribute of the keychain item, or a search option. For example, you can use the k​Sec​Class key to specify that the keychain item is an Internet password, that it has a specific creation date, that it is for the HTTPS protocol, and that only the first match found should be returned. The keys that can be used for this purpose and the possible values for each key are listed in the Keychain Services section.

See the discussion section of the Sec​Item​Copy​Matching(_:​_:​) function for information about how to construct a keychain-item search dictionary.

func Sec​Item​Copy​Matching(CFDictionary, Unsafe​Mutable​Pointer<CFType​Ref?>?)

Returns one or more keychain items that match a search query, or copies attributes of specific keychain items.

func Sec​Item​Update(CFDictionary, CFDictionary)

Modifies items that match a search query.

func Sec​Item​Delete(CFDictionary)

Deletes items that match a search query.

Item Class Key Constant

Key constant used to set the item class value in a search dictionary.

Item Class Value Constants

Attribute Item Keys and Values

You use keys in a search dictionary to specify the keychain items for which to search. You can specify a combination of item attributes and search attributes (see Search Keys) when looking for matching items with the Sec​Item​Copy​Matching(_:​_:​) function. This section lists all the keys that specify keychain item attributes. The description of each item indicates what the possible values are for that key. In a few cases, the programming interface provides a set of constants that you can use as values for a specific key. Those value constants are also in this section, following the descriptions of the keys.

Attribute Item Keys

Each type of keychain item can have a number of attributes describing that item. For the possible types of keychain item and the attributes that can be specified for each, see Keychain Item Class Keys and Values.

Protocol Values

Values that can be used with the k​Sec​Attr​Protocol attribute key.
