To provide secure communication through an SSL (Secure Socket Layer) connection, the GroupWise Agents (MTA, POA, and Internet Agent) require access to a server certificate and private key.
You can use the GroupWise Generate CSR utility (GWCSRGEN) to generate a Certificate Signing Request (CSR) file and a Private Key file.
The CSR file, which is BASE64 encoded, contains the information required for a Certificate Authority (CA) to issue you a server certificate. This server certificate, when paired with the private key generated by the GroupWise Generate CSR utility, enables GroupWise agents to use SSL connections.
For information about SSL and certificates, see Server Certificates and SSL Encryption.
