ImportKey Method
Imports the key specified by UserId to the current keyring.
Syntax
keymgr.importKey(fileName, userId, [callback])
Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for this method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
This method imports the key specified by UserId from the key file specified by FileName into the current Keyring. The imported key will be automatically selected and available in the Key property.
If the FileName specifies a key file which contains multiple keys only the key belonging to UserId will be imported.
If UserId is set to "*" or "" (empty string) all keys in the key file will be imported. The ImportAllKeys setting controls the behavior of the class in this case.
Note: If you simply wish to select a key in the current ring set KeyUserId instead.
