Certificates are required so that the MailSealer can work correctly, these certificates are managed here.
The certificate management includes private, public, certificate authorities and the REDDOXX CA
Certificates can be added, exported, validated or deleted
The Trust status for root certificates can be adjusted with a right click -> Trust Status
If a certificate is in the wrong section, you can use right click -> certificate to move it to the correct section
In order to encrypt a mail via S/MIME the public key of the recipient, the private key of the sender and the key of the certificate authority is required
When using the REDDOXX CA, private keys can be automatically created, if configured in the settings
In order to import a huge amount of private certificates at once, all certificates and corresponding keys need to be available in pem format and all together copied in a single file.
Then just go to MailSealer > S/MIME Certificates > Private End-User Certifiates > Add > public certificates, then browse for the pem file (that contains all certificates and keys in pem format) and confirm with save.
Certificates are checked for validity when they are added (Validity period, Revocation Lists, Certificate Chain) and when they are used for incoming or outgoing E-Mails.
The following Trust States for root certificates are possible:
Normal: The certificate is checked for validity/trustworthiness
Untrusted: The certificate is not checked. It is not trustworthy.
