Overview

Package aesnicheck provides a simple check to see if crypto/aes is using AES-NI instructions or if the AES transform is being done in software. AES-NI is constant-time, which makes it impervious to cache-level timing attacks. For security-conscious deployments on public cloud infrastructure (Amazon EC2, Google Compute Engine, Microsoft Azure, etc.) this may be critical.

See http://eprint.iacr.org/2014/248 for details on cross-VM timing attacks on AES keys.
