The method includes receiving an indication of a first number X representing how many of the key shadows are to be generated, receiving an indication of a second number Y representing how many of the key shadows are to be required for decrypting an encrypted message, determining or receiving a master key for decrypting the encrypted message, and determining X key shadows of the master key. Y of those key shadows is sufficient to generate a range of more than one possible master keys that can be computationally feasibly searched for the master key. Less than Y of those key shadows is insufficient to determine any part of a value for the master key. Also, a technique of decrypting an encrypted message using Y of the key shadows.
