This question already has an answer here:
I am making a choice between StartSSL and positiveSSL($4.99/yr). I want to know the difference between them. As I know, SSL is used to encrypted the connection between client and server so that data transferred(cookie) will not be under 'man-in-the-middle' attack.
Doing some searches on StartSSL, I found a website said 'They don't do any verification beyond email address and the domain name, so they aren't good for ecommerce.' What does this mean? Does StartSSL encrypt the data transfered? If no, can you tell me which type of SSL will encrypt data in the connection?
I just want the post data and cookie will be encrypted in https request.
