Methods and systems are provided of managing a cryptographic key. A first key component is received from a first key custodian. A second key component is received from a second key custodian. A key operation is performed on the first and second key components to generate the cryptographic key. A cryptographic-key number is assigned to the cryptographic key. A key form is printed specifying the cryptographic key. An association is recorded between the cryptographic-key number and an electromagnetic tag identifier coupled physically with the key form.
