The package will install a configuration file to /etc/ehsm, open the ehsmd_config file with an editor
and fill in the eHSM serial number where indicated (you can copy it from the eHSM Manager device info screen).
The config file should look like this:
EHSMD_OPTS=-d <devicesn> -p 4433 -i ehsm1.ellipticsecure.com -key /etc/ehsm/key.pem -crt /etc/ehsm/cert.pem -ca /etc/ehsm/ca.pem
Copy the certificate received (from step 2 above) to /etc/ehsm/cert.pem and the key file (from step 1 above) to /etc/ehsm/key.pem.
