SecKeyChain Class

Definition

Access to the operating system keychain.

public class SecKeyChain : ObjCRuntime.INativeObject
type SecKeyChain = class
    interface INativeObject
Inheritance
SecKeyChain
Implements

Remarks

This class can be used to add, remove, update or query the iOS or MacOS keychain. MacOS is limited to a single kind of password (SecKind.InternetPassword) while iOS offers a wider range of options.

Use QueryAsData(SecRecord, Boolean, Int32, SecStatusCode) to get values from the keychain as a binary blob. Some of the overloads can also return binary blobs that are suitable to be stored on disk, or passed to another process.

Use QueryAsConcreteType(SecRecord, SecStatusCode) to get a SecCertificate, a SecKey or a SecIdentity back from the keychain.

Use M:Security.SecKeyChain.QueryAsRecord* to get a strongly typed SecRecord with the results of your query.


var query = new SecRecord (SecKind.InternetPassword) {
   Sever = "bugzilla.novell.com",
   Account = "miguel"
};
var password = SecKeyChain.QueryAsData (query);
Console.WriteLine ("The password for the account is: {0}", password);

Properties
