NOTE Using Luna HSM Firmware 7.7.0 and newer, 3DES keys have a usage counter attribute (CKA_BYTES_REMAINING) that limits each key instance to encrypting a maximum of 2^16 8-byte blocks of data when the HSM is in FIPS mode (HSM policy 12: Allow non-FIPS algorithms set to 0). When the counter runs out, that key can no longer be used for encryption, wrapping, deriving, or signing, but can still be used for decrypting, unwrapping, and verifying pre-existing objects.
The CKA_BYTES_REMAINING attribute is available when HSM policy 12: Allow non-FIPS algorithms is set to 0, but cannot be viewed if the policy is set to 1.
The attribute is preserved through backup/restore using a Luna Backup HSM 7; restoring the key restores the counter's setting at the time of backup.
The attribute is not preserved through backup/restore using a Luna Backup HSM G5; restoring the key resets the counter to the maximum.
