Bug description:
  openssl-ibmca usually requires libica2 and libica-utils for proper
  functioning and all required tooling (like icainfo, icastats, etc.)

  But after the installation of these packages and the configuration, with is like this:
  sudo tee -a /etc/ssl/openssl.cnf < /usr/share/doc/openssl-ibmca/examples/openssl.cnf.sample
  sudo vi /etc/ssl/openssl.cnf
  adding the following line as the first active one:
  openssl_conf = openssl_def
  and removing or commenting all other occurrences of that line in the config file
  and saving and closing the openssl.cnf file
  this output of the openssl engine command is expected:

  $ openssl engine
  (dynamic) Dynamic engine loading support
  (ibmca) Ibmca hardware engine support

  or even more precise these chiphers should be listed in case of "-c":

  $ openssl engine -c
  (dynamic) Dynamic engine loading support
  (ibmca) Ibmca hardware engine support
   [RAND, DES-ECB, DES-CBC, DES-OFB, DES-CFB, DES-EDE3, DES-EDE3-CBC, DES-EDE3-OFB, DES-EDE3-CFB, AES-128-ECB, AES-192-ECB, AES-256-ECB, AES-128-CBC, AES-192-CBC, AES-256-CBC, AES-128-OFB, AES-192-OFB, AES-256-OFB, AES-128-CFB, AES-192-CFB, AES-256-CFB, SHA1, SHA256, SHA512]

  But instead openssl is giving this error, due to a missing "libica.so":
  $ openssl engine

  $

  There is no libica.so that is shipped with any of the above packages (verified with dpkg -l) or otherwise available in the filesystem:
  $ sudo find / -name "libica.so" 2>/dev/null
  ubuntu@HWE0001:~$ 

  But there is a different verison of that libica:
  $ sudo find / -name "*libica.so*" 2>/dev/null
  /usr/lib/s390x-linux-gnu/libica.so.2
  /usr/lib/s390x-linux-gnu/libica.so.2.6.1
  $ 

  So there are right now two workarounds:
  1)
  creating a (symbolic) link from libica.so.2 to libica.so, like
  $ sudo ln -s /usr/lib/s390x-linux-gnu/libica.so.2 /usr/lib/s390x-linux-gnu/libica.so 
  that allows openssl to find a library named 'libica.so':
  18:15:00: frank.heimes@xxxxxxxxxxxxx: ubuntu@HWE0001:~$ openssl engine
  (dynamic) Dynamic engine loading support
  (ibmca) Ibmca hardware engine support
  But this could lead to issues in case of any potential functions or interface changes there we introduced with libica.so.2
  2)
  installation of the "libica-dev" package that provides a (development) version of libica.so:
  $ dpkg -L libica-dev | grep libica.so
  /usr/lib/s390x-linux-gnu/libica.so
  $

  But the hardware crypto exploitation should work out of the box w/o
  the link or the libica-dev package.

  Either libica.so should be shipped (in addition to libica.so.2) with
  the proper dependency to openssl-ibmca - openssh-ibmca should make use
  of libica2 instead of libica.so.2...
