With many security issues with TLS 1.0 and using SSL Encrypted FTP services, it is time to move on the TLS 1.2 which is an updated version of the SSL layer with better encryption and security.

Some of the FTP sites which I had have implemented TLS 1.2 on various linux systems, however I really needed to implement this on my G6 FTP which i still like to use and have found it a top performance FTP server on windows systems. So to do this we do the following:

Drop in OpenSSL >=1.0 (libeay32.dll, ssleay32.dll, libssl32.dll) as a replacement in your G6 installation directory, and add the following line to your settings.ini files for SSL-enabled FTP domains, you can find the files in the Accountsyourdomainname subfolders of your G6 FTP installation (scroll across for the full line to copy):

SSLCipherList=ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-DSS-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384:ECDH-RSA-AES256-GCM-SHA384:ECDH-ECDSA-AES256-GCM-SHA384:AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:DHE-RSA-AES128-GCM-SHA256:ECDH-RSA-AES128-GCM-SHA256:ECDH-ECDSA-AES128-GCM-SHA256:AES128-GCM-SHA256:ECDHE-RSA-RC4-SHA:ECDHE-ECDSA-RC4-SHA:ECDH-RSA-RC4-SHA:ECDH-ECDSA-RC4-SHA:RC4-SHA:RC4-MD5:PSK-RC4-SHA

I have included Open SSL Files for your convenience to download here and copy to the G6 install directory:
