First upgrade to DSM 7.0 through Control Panel

KMIP for key management

Follow the guide to install KMIP on a Synology NAS server and client
What this guide does not mention is how to generate working certificates for DSM 7.4 and later, which hardened the certificate requirements, so follow my guide here:
1. The default, out-of-the-box self-signed Synology certificate will fail on DSM 7.4
2. Login to your NAS on the command line with SSH and elevate to root
3. Download Synology's official KMIP certificate script:
```
wget supweb.synology.com/support_web/kc_tool/how_to_gen_cert_for_kmip_services/gen_kmip_certs.sh
```
4. Run the script as root:
```
bash gen_kmip_certs.sh kmip_certs
```
  The second parameter kmip_certs is the name of a shared folder the script will create to store the certificates
5. Upload the generated scripts in /volume1/kmip_certs to your local computer you use to access your DSMs through your web browser, after which you can remove the shared folder and it's content
6. The script will generate the following certificates:
7. On the server NAS
