You can aks the other party to resend you a message from before (one that doesn't matter). Ie. Can you confirm this is you: send me a message from 5 messages back using the quote function. (you know what is said 5 mssgs back so you can pick a non sensitive one, and they can do the same to you) edit: nvm, if this is man in the middle then that doesn't matter because you still exchange with each other and its not a hijack. Sorry, I made a mistake.
