Detailed Description

ARIA block cipher.

   The ARIA algorithm is a symmetric block cipher that can encrypt and
   decrypt information. It is defined by the Korean Agency for
   Technology and Standards (KATS) in <em>KS X 1213:2004</em> (in
   Korean, but see http://210.104.33.10/ARIA/index-e.html in English)
   and also described by the IETF in <em>RFC 5794</em>.
