SSL-encryption for SQL

It is possible to encrypt traffic from the complex server and/or the global settings program to the SQL-server.

MS SQL Server
1. In the SQL server connection windows you have to specify a prefix ssl:// before the server name.
For example: ssl://server-sql
2. It is necessary to make settings at the SQL server itself to install certificates (see here)
Note: if the certificate is self-signed and not added to trusted, then a connection error will be received.

PostgreSQL
The connection to the SQL server uses a secure, encrypted SSL connection (if enabled on the server), or plain without encryption (if not enabled on the server). To enable SSL on the server, just set the parameter ssl=on in postgresql.conf, and also copy certificate files server.crt, server.key to the same folder (usually, when installing on Linux, a certificate is created automatically and nothing additional needs to be done).
