Public bug reported:
Description:
zkey: Fix re-enciphering of EP11 identity key of KMIP plugin
Symptom:
When re-enciphering the identity key and/or wrapping key of the zkey KMIP
plugin via 'zkey kms reencipher', the operation completes without an error, but
the secure keys are left un-reenciphered. A subsequent connection attempt with
the KMIP server will fail because the identity key is no longer valid.
Problem:
The re-enciphered secure key is not copied back into the key token buffer.
Also, the the public key part, i.e. the MACed SubjectPublicKeyInfo (SPKI)
structure must also be re-enciphered (i.e. re-MACed), since the MAC is
calculated with the EP11 master key.
Solution:
Copy the re-enciphered secure key back into the key token buffer, and also
re-encipher the public key part.
Reproduction: Perform a master key change on the EP11 APQNs used with the
KMIP plugin.
