I'm signing up with another ISP.  I end up at a page on the ISP's site:

http://www.plus.net/products/option.html?type=plus&speed=2000&hardware=usb&contract=FreeActivationAnnual&js=1 and I click on the "Buy Now" link.

Opera 8.02 then tells me that the page is using outdated encryption. Specifically, TLS v1.0 128 bit ARC4 (512 bit RSA/SHA)

However, if I visit that page with IE or FF, they both say that the certificate is SSL 3.0.

Why would Opera consider that TLS is inferior to SSL?

And why does Opera 8 get TLS anyway, when other browsers get SSL?

LLS 1.0 = SSL 3.0 (I think IE renamed it because people were thinking TLS 1.0 < SSL 2.0)

The reason Opera is warning is the key length. 128 bit with a 512 bit key isn't very strong (if you have the computing power of the NSA it's trivial). The key should be 768 or 1024-bit - AFAIK they haven't been cracked yet.
