Subject: [PATCH 1/4] genprotimg: remove DigiCert root CA pinning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Remove the DigiCert root CA pinning. The root CA used for the chain of trust can
change in the future therefore let's remove this check. If someone wants to
enforce the usage of a specific root CA it can be selected by the genprotimg
command line option `--root-ca $CA`. Make it transparent to the user which root
CA is actually being used by printing the subject name of the root CA to stdout
in verbose mode.

Subject: [PATCH 2/4] genprotimg/check_hostkeydoc: relax default issuer check
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
While the original default issuer's organizationalUnitName (OU)
was defined as "IBM Z Host Key Signing Service", any OU ending
with "Key Signing Service" is considered legal.
Let's relax the default issuer check by stripping off characters
preceding "Key Signing Service".

Subject: [PATCH 3/4] libseckey: Fix re-enciphering of EP11 secure key
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The re-enciphering of EP11 asymmetric secure keys does not work.
First, the result of the re-encipher operation of the private key
part must be copied back into the user supplied key token buffer.
Second, 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.
