EDIT: This post is corrected – please review comments:- Your email is now orders of magnitude more secure than your online banking–is that right?
This is not new because Google was already using 1024 bit security but with this upgrade to 2048 bit, it is time for banks to at least re-visit their security level and offer exper commentary. Most banks are using 128 bit (RBC for example) with some banks having already gone to 256 bit (Peoples Trust, Standard Chartered, Members Advantage Credit Union)
The reason Google are doing this is based on concern that the American Government through the NSA are able to decrypt what we have assumed is secure data transmission.
When internet started email and browsing activity was unencrypted and online banking was secure. Now the situation is reversed. Surely we should be looking at financial services access with at least as much rigour as email?
Out with the old: Stronger certificates with Google Internet Authority G2 | Google Security blog
We take the security and privacy of our users very seriously and, as we noted in May, Google has been working to upgrade all its SSL certificates to 2048-bit RSA or better by the end of 2013. Coming in ahead of schedule, we have completed this process, which will allow the industry to start removing trust from weaker, 1024-bit keys next year.
