When using Hornetsecurity Email Encryption Services it is possible to provide your own S/MIME and PGP certificates for backend deploy. You can deliver the certificates in a support request (support@hornetsecurity.com). To make sure that the provided certificates can be deployed, the following format is required:
Public Keys:
- PGP: [email@domain.tld_NUMBER.asc]
- S/MIME: [email@domain.tld_NUMBER.der]
Private Keys:
- PGP: [email@domain.tld.asc]
- S/MIME: [name@domain.tld.pem]
- text file containing the S/MIME passphrase: [name@domain.tld.txt]
Please also mention the amount of certificates that should be imported and deployed within your support request, especially in case of business relevant dependencies, since it may take a few days till the process is finished with varying amount of total keys.
