Encryption works. But as computing power increases the time requires to brute force crack your encryption keys decreases. This article from Natural News notes that the NSA is archiving all eencrypted emails and transactions in the hopes that increases in computing power, including quantum computing, will allow them to be decrypted in the next few years. Note that it mentions 256-bit AES and RSA keys. Upgrade your encryption to elliptic encryption if your apps support it. If your apps don’t support it, look for ones that do.
That said, the NSA also has a vested interest in making people believe that using encryption is useless. So this could also be a smoke screen. Cover your bases and use the best encryption practicable. The government has no business reading your correspondence without a valid warrant.
All encrypted emails, files and hard drives that currently rely on 256-bit encryption (such as AES or RSA) may be retroactively broken by the NSA in the next three years, thanks to rapid advances in quantum computing recently announced by Google scientists.
The NSA is currently archiving all encrypted communications and storing the digital files on offline storage servers in its “Bumblehive” domestic spying facility in Utah. Currently these digital files cannot be broken because classical computing presents a strongly asymmetrical complexity problem that makes breaking encrypted files prohibitively time consuming and expensive. Files encrypted with 2^n bits currently present computational complexity that requires 2^n computer power to break. In other words, encrypting files is easy (linear), but breaking encryption is incredibly difficult (logarithmic).
But rapid advances in quantum computing transform the breaking of encryption from a logarithmic mathematical problem to a linear problem, collapsing the complexity to 2 * n instead of 2 ^ n…
