/*
* file : echo_vperm.c
* version : 1.0.208
* date : 14.12.2010
*
* - vperm and aes_ni implementations of hash function ECHO
* - implements NIST hash api
* - assumes that message lenght is multiple of 8-bits
* - _ECHO_VPERM_ must be defined if compiling with ../main.c
* - define NO_AES_NI for aes_ni version
