Google is a step ahead of Yahoo here, where it has upgraded all of its SSL certificates to 2048-bit, but now Yahoo is pushing ahead with some hopefully NSA-proof encryption to its information.
Yahoo CEO, Marissa Mayer, has reiterated the fact that Yahoo has never handed over information from its datacenters to the NSA, or any other government agency for that matter. The CEO said there is nothing more important than users' data and privacy, and that the company is extending the SSL encryption with a 2048-bit key for Yahoo Mail, and all Yahoo products.
The 2048-bit goodness should encrypt all Yahoo datacenter information by the end of Q1 2014, so around 4 months from now. From here, it will offer users an option to encrypt all of their data in and out of Yahoo by the end of March next year. The company will also work close with their international Mail partners to make sure that co-branded accounts are also 2048-bit protected.
