Module ni

AES block ciphers implementation using AES-NI instruction set.

Ciphers functionality is accessed using BlockCipher trait from the cipher crate.

Vulnerability

Lazy FP state restory vulnerability can allow local process to leak content of the FPU register, in which round keys are stored. This vulnerability can be mitigated at the operating system level by installing relevant patches. (i.e. keep your OS updated!) More info:
