Before importing TLS certificates via the web interface of Kaspersky Secure Mail Gateway, you have to prepare them for import.
You can prepare certificates of the following types for import:
Self-signed certificates are normally used to test and debug SSL and TLS encryption of connections. You are advised to use certificates signed by a certification authority (CA certificates) on public servers.
To import a TLS certificate from file:
The file selection window opens in the browser that you use.
The certificate file (Preparing a self-signed TLS certificate for import, Preparing to import a CA-signed TLS certificate) must contain the TLS certificate and a private TLS key with the PEM extension. The private key must not be encrypted or password-protected.
The file selection window closes.
The TLS certificate appears in the list of TLS certificates in the workspace of the main window of the application web interface.
