+ This module should only be used for low power (router) devices
+ without hardware AES acceleration (e.g. caam crypto). It reduces the
+ size of the AES tables from 16KB to 8KB + 256 bytes and mitigates
+ timining attacks. Nevertheless it might be not as secure as other
+ architecture specific assembler implementations that work on 1KB
+ tables or 256 bytes S-boxes.
