ePortal with TLS 1.2 in an eFlow environment ≤ 5.2

In an eFlow ≤ 5.2 environment, TLS 1.0 is required. When the customer's E-Mail-System requires TLS 1.2 for security reasons, the resulting conflict for ePortal can be resolved by two registry settings.


After completing this how-to you will have ...

First Step

It is required that at least .NET Framework 4.5 is installed. If not, this must be done in a first step.

Second Step

Two key and DWORD entries must be set in the Windows registry of the computer running the ePortal:

Windows Registry Editor Version 5.00



A reboot is required after this change.

What's Next

The registry settings instruct the secure channel to use the strongest possible cryptography at the transport layer. This allows the ePortal to use TLS 1.2 when communicating with the e-mail system and TLS 1.0 when communicating with eFlow.
