AES encryption with 256 bit keys offers the strongest protection of data available in a FIPS-approved encryption algorithm. Indeed, the National Security Agency (NSA) considers the design of AES and the strength of its key sizes sufficient for protecting its classified information. In CNSS Policy No. 15, they state key sizes of 128, 192, and 256 bits are sufficient for SECRET and 192 and 256 bits for TOP SECRET. See CNSS Policy No. 15, Fact Sheet No.
