How the ciphers order is defined during a transfer between two CFT



Resolution

CFT prioritizes the cipher suites as displayed in the Order used column in the chapter 'Manager cipher suites'.

It concerns all SSL connections: Passport AM, CG, Sentinel and file transfers.

The user cannot order its preferred cipher suites.


The order is hard-coded for security reason.


Too often the users put the less secured cipher suites first.



The aim is to have a secured product even for less informed users.



The fact that AES-128 comes before AES-256 is due to a compromise between performance and security.
