The password the RepAgent thread uses to log in to Replication Server is always encrypted before it is stored in the sysattributes file of the database. However, you can choose whether or not to encrypt other replication system passwords.
The rs_init program allows you to enable password encryption when you install or upgrade the replication system. This allows you to encrypt passwords throughout sensitive areas of the replication system. Once the system is installed or upgraded, you can use rs_init at any time to enable encryption.
If you enable password encryption for a Replication Server, new passwords, passwords contained in the Replication Server configuration file, and passwords stored in the RSSD are all encrypted.
For details on enabling password encryption using the rs_init program, refer to the Replication Server installation and configuration guides for your platform.
