Abstract

A label corresponding to a cryptographic key is stored at a first computational device. A user provided label is received at a second computational device. The user provided label is sent from the second computational device to the first computational device. The user provided label is compared to the label stored at the first computational device. The cryptographic key is used to perform cryptographic operations on data, in response to determining that the user provided label matches the label stored at the first computational device.
