If I am communicating over a secure line (secured using SSL or TLS) and I send the server a message.
Could someone eavesdropping tell what that message was if they knew before hand a list of messages I am likely to send.
E.g. I send a message saying "Execute order 66" over a secure line. Someone was eavesdropping and suspected that I was going to send this order. Could they verify that I just sent that specific message by comparing the sent message with the same message encrypted with the same public key.
