By now we all know that you should not buy a product unless you see the little lock in your browser. The lock symbolizes that they are using an SSL Certificate which encrypts the page with 128 bit encryption. This has been in place for a long time and everyone online has come to trust it.
This is no longer the case.
Just before the new year it was exposed that SSL and MD5 were both cracked. That means we can no longer trust every site that has SSL.
Netcraft’s SSL Survey shows that 14% of valid third party SSL certificates have been issued using MD5 signatures . an algorithm that has recently been demonstrated to be vulnerable to attack by producing a fake certificate authority certificate signed by a widely-trusted third party certificate authority.
The researchers achieved this by producing a hash collision . they submitted valid certificate requests to a certificate authority (CA), while producing a second certificate that had the same signature but entirely different details. When the CA signed the valid certificate, the signature applied also to the invalid certificate, allowing the researchers to spoof any secure website that they liked. This attack is the first practical use against SSL of already-known attacks against the MD5 checksum algorithm.
How can I check if my SSL or the site I am using SSL is susceptible?
Double click the lock icon and look for the Signature Algorithm. If it says MD5 your SSL is not secure. If it says anything else you should be ok.
Here is what it looks like in IE…

and here in FireFox…

If you come across any SSL with MD5 then let them know about his post.
Note – All SSL’s sold by BlueFur.com do not use the MD5 so there is no need to worry if you purchased one from us.
