Description
I have an OpenVPN client configured with Data Encryption set to None. For some reason, we don't need data encryption due to our low network bandwidth.
After upgrading to pfSense Community Edition 2.9.0, the connection fails with:
OpenSSL: error:0308010C:digital envelope routines::unsupported: ... Algorithm (none : 0)
It looks like OpenSSL was also upgraded, and OpenVPN now relies on the newer OpenSSL 3.5, which does not allow the `none` cipher.
Therefore, we must enable Data Encryption. However, we expected pfSense to continue supporting Data Encryption = None, as it did in the previous version
