we are using winSCP to connect to a SFTPServer, We need to use a AES-256 Cipher. In our firewall we see the tracelogs and we see the following problem:
- if we (client) start the negotiation we are able to use the cipher we want.
- but if the server is who start the negotiation use other not secure ciphert and we accept it.
Is there a way to reject this? Is there a way to force to use the cipher we want?
