Guys, While I appreciate the vibrant discussion, I was not asking for the pros and cons of hiding the header information, whether or not one feels it promotes security, and whether one believes meddling with this makes one a geek or not. In many people's desire to announce their opinion on the

The OP, however, is right. Why report the version at all to the user of a website? There is no need to let them know you are even running OpenSSL let alone the version being run. I'm not talking about security through obscurity. I'm referring to common sense. Don't tell people what you

Blocking the version number is worse than reporting stale version information. At least they can determine a minimum security level. Incorrect information cuts both ways, helping the hacker and legitimate user at the same time. Better to prefer the legitimate user's interest. SP [EMAIL

The problem is that virtually no legit users will ever look, but the hackers definitely will. I'll admit (being a geek) that I checked once when logging into my banking site for the first time many years ago. So maybe I was 'benefitted' that one time (and my case is definitely not typical),
