A little over a month ago Perry Metzger asked about free assembler
language implementations of Rijndael for x86. Helger Lipmaa, whose
commercial assembler language version seems to be the fastest,
mentioned Brian Gladman as having the best free C implementation.
Gladman's web page now says that

Or did I dream that?
No, you heard

First, my question was caused since Perry(?) did not originally specify
*why* he needs an assembly code; and secondly, since the referred 186
assembly code might be slower than the best C codes for Pentium. On the
other hand, the best (commercial) assembly implementation of Rijndael for
P3 is 50%
