I think he was referring to self-signed certificates, which you can create yourself.
These certificates causes your browser to display a warning (and Firefox warning is pretty dissuasive), because they aren't secure (they're vulnerable to man-in-the-middle attacks).

StartSSL "class 1" certificates, albeit free, are signed by a Certification Authority (StartCom), and display no warning in your Web-browser. (They aren't vulnerable to man-in-the-middle attacks).
yep.
but as long as typical hijacker, which is frequently feds/isp, can/might hijack you isp, he can mimic CA activity too, with help of altered browser binary update. there is no way to combat that, than enforce both IPv6 deployment/usage for any kind of mission-critical/society-critical/survival-critical intrastructure/network with enforced crypto and DNSSec too, while both isn't invulnerable, but step ahead.

you can use SSL without a paid certificate. given the users trust your non-validated cert.
which make everything you do, useless, because someone can [for example. not only one]can intercept/proxy you traffic, redirecting it.
thats why/how signing/PKA/PCS work and WHY you actually NEED "paid" certificate.
Do you suggest me StartSSL or another one else?

The Class1 validation validates your domain name. (They do it by sending you a verification link to [email protected] or a similar address.)
The Class2 validation validates your identity. (You have to send them a picture of your identity card).

Now, as far as encryption goes, I don't think there's a difference between the different classes.

DISCLAIMER: I haven't used any of their certificates myself. (Yet. Except their client certificate.)

Yes, their basic certificate isr free.

From their FAQ:

Quote from: StartCom
90.) Why are Class 1 certificates free?
The philosophy of StartCom is guided by the principal that our services are charged according to the effort we have to invest. Since Class 1 certificates are domain and/or email validated only and the process is performed mostly by electronic and automatic means, StartCom doesn't apply any fees for this type of certification. StartCom started the certification authority a few years ago with the goal to provide free digital certification and adopted a unique business model previously unknown in this industry.

I'd suggest you have a look at their website: StartSSL™ Comparison Chart

I see that I don't think I really need the things that the free version doesn't offer. The only thing which I am in doubt is the validation level: what the class two or three comports than the class one?

Nope, they sign it. They're a Certification Authority.
For free? I don't know so much about certificates.

StartSSL (http://www.startssl.com/) delivers free SSL certificates.
Like self-signed certificate? And so completely useless?

It depends on where you decide to buy your certificate.

StartSSL (http://www.startssl.com/) delivers free SSL certificates. Their root CA certificate is accepted by all browsers, as far as I know.
Their cheapest paid-for certificate costs $60 and is valid for 2 years. (It's not that expensive IMHO)

Hi there,
I'm writing the code for a pool but I am sure that some informations need to transfer in a secure connection with the server. Most pools use an SSL certificate to make the connection secure: how much could it cost? Initially I thought that I could use javacript to encrypt with sha2 the password field in the form before sending it to the server, but there are other informations that I can't send in encrypted form, as the bitcoin address of every user. So I found this but I am not very convinced about that. There other ways? Which is the best?

Thanks,
turlando.
