lszcrypt now shows a card/queue which is in 'deconfigured' state as
'deconfig' in the STATE column (verbose and non verbose mode).
chzcrypt became two new options: --config-on and --config-off to
switch one or more card devices to 'configured' or 'deconfigured'

Both applications are able to handle older kernels which do now

During using of ziorep_utilization utility for generating of CSV format output,
there is one extra comma added after Bus-ID column in virtual adapter report
for each line. This creates one extra column with empty content for each

no content, all subsequent columns have shifted content from previous

of extra comma.

To retrieve a secure key from EKMF Web, a Elliptic-curve Diffie-Hellman
(EC-DH) protocol is used to securely transport the key, without revealing
the key to be transported in clear. The key to be transported remains
encrypted all the time, either encrypted with the master key of the
cryptographic adapter on the source or target side, or with a transport
key, that is derived using the EC-DH key agreement protocol. The transport
key is also a secure key, itself encrypted with the master key of the
cryptographic adapters on both sides.
To generate the transport key, each side generates a new secure ECC
session key with its cryptographic adapter. This session keys are then
used with EC-DH to derive the secure transport key. The secure key to
be transported is then exported by EKMF Web under the transport key, is
sent to the client, and is then imported using the transport key.
The key retrieval request is signed using the identity key of the client.
EKMF Web knows the public key of the client's identity key through a one
time registration process, and can therefore verify the signature with
the client's public key. The response is also signed by the EKMF Web
server's identity key, and the client can verify the signature with the
server's public key that it retrieved once during registration.
