Google get per August about on ssl certificates with 2048bit keys. Also the root certificate, and the ssl certificates are signed, will receive an upgrade to 2048bit. For the end of this year should the roll out be ready.
That announced Google on its Online Security Blog. In August, the company starts with the upgrade of the certificates, so that says enough time for a careful rollout of the stronger encryption. Now, Google is still using 1024 bit encryption for the root certificate.
According to Google, most clients do not experience any problems of the changes, but it may happen that some configurations, some steps should be taken to prevent complications. This applies mainly to client software that is built into some phones, printers, set-top boxes, game consoles and cameras. On his own blog, the company from which cases can be done.
The advantage of the upgrade is that for attackers and more difficult for the encryption through brute force to crack. At this time, the hackers had to be practically not feasible to the 1024-bit encryption to this way to crack, but it is wise to arrange to move to stronger encryption to hackers. Hacks on the certificaatverstrekkers itself, however, pose a greater risk, as previously duidellijk was by hacks on DigiNotar, VeriSign and Comodo.
