DES, MD5 and SHA1 code size

Christian Scheurer

Hello,

we made a straight forward port of the DES, MD5 and SHA1 algorithms from OpenSSL library (http://www.openssl.org) without optimizing the source code.
The following code size is indicated in the .map when compiling using the default compiler settings of C166 v4.27 for a C167CS MCU (Hlarge memory model):

Module  Code     ROM     RAM
=============================
DES	25'246	 4'631   162
MD5	20'738      16	   4
SHA1	39'726      20	   4

The code size seems to be quite large. What code size can be expected from an optimized implementation of these common algorithms?

Thank you for any comment,
Christian
