After the PKCS #7 data is imported, the original \hp\sslshare\cert.pem certificate file for Windows
and /opt/hp/sslshare/cert.pem (/etc/opt/hp/sslshare/cert.pem in HP SMH 2.1.3 and later on Linux x86 and x86-64) is overwritten
with the system certificate from the PKCS #7 data envelope. The same private key is used for the new imported
certificate that was used with the previous self-signed certificate.
This private key is randomly generated at startup when no key file
exists.
