Close Method
Closes the logical storage.
Syntax
cryptokeystorage.close(save, [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
Use this method to close logical storages connected to PKCS#11-compliant hardware security modules,or storages of similar persistent kinds. Closing a persistent storage with thismethod is important, as unused but unclosed storages consume extra resources andmay result in eventual key locks.
