Drivers with deactivated encryption may silently enable encryption

Detail name	Value
Changelog Number	15398
Type	Bug
Status	Resolved
Affected Versions	Exasol 7.0.0
Fix Versions	Exasol 7.1.0
Resolution Date	2021-08-03

Background

Exasol drivers (JDBC, ODBC, ADO.NET) use encrypted connections by default to communicate with the database. Encryption can be deactivated on the driver-side.

Description

The driver will silently enable encryption if the following conditions are met

• Encryption is deactivated in the driver (e.g. by using the connection string parameter encryption=0 for JDBC)
• Encryption is enforced in the database (database parameter -forceProtocolEncryption=1)

Workaround

There is no workaround

Fix

Those connections now fail instead of silently enabling encryption.
