Heya, got a question about whois and SSL certificates.

Now, when I check out https://secure.newegg.com/, and look at the encryption details, the certificate is issued by verisign and is all valid, but when I check out whois.sc, it says no valid SSL. The details seems to be in order, but whois.sc doesn't seem to display it. Any idea as to why this is ? I am assuming whois is wrong on this, but I was just wondering why this happens. Everything seems to be in order...
