As we move to a world of hybrid data centers that span both private and public clouds, encryption will become increasingly ubiquitous and important. While the physical control of infrastructure becomes less and less relevant, the logical control of encryption becomes the foundation of trust. As such, the integrity of an encryption solution moves more centrally into the spotlight. 

The current state of the art as defined by the NSA is AES-256 bit encryption. This very strong level of encryption is not practical to break with known computing hardware. In order to trust the encryption, however, we need to trust the libraries and the hardware that are at the root of an encryption scheme. And if we’ve learned anything over the past few years, there is reason for concern.
