Tectia client tools for z/OS supports also user key pairs generated with OpenSSH. The OpenSSH keys can be specified in the ssh-broker-config.xml file by using the key-stores element. An example configuration is shown below:

<key-stores>
  <key-store type="software" 
             init="key_files(/home/exa/keys/id_dsa.pub,/home/exa/keys/id_dsa)" />
  <key-store type="software" 
             init="directory(path(/home/exa/.ssh))" />
</key-stores>

This example adds a key called id_dsa and all keys from the user's default OpenSSH key directory (.ssh under the user's home directory).

The public key can be uploaded to the server the same way as with standard SSH2 keys. See Uploading Public Keys from z/OS to Remote Host.
