https - Can a hacker access the data in my first request even if SSL cert is invalid? -

-

this question in context of web-services. if invoke web-service on ssl alongwith required data service; ssl error, if ssl cert invalid, , wont make further requests. happened data sent in first request ? transmitted attacker ? can decrypt ?

in typical website scenario hardly arises, our request server has hardly got private data - once server sends form, proceed confidenial data.

thanks.

ssl/tls established before data sent. consequently if there error, nothing sent , data safe.
