<DIV id=cont_right style="WIDTH: 495px">The MD5 Algorithm takes as input a
message of arbitrary length and produces as output a 128-bit "fingerprint"
or "message digest" of the input. It is conjectured that it is
computationally infeasible to produce two messages having the same message
digest, or to produce any message having a given pre-specified target
message digest. MD5 is aimed at 32-bit machines and intended for digital
signature applications, where a large file must be "compressed" in a
secure manner before being encrypted with a private key under a Public-Key
Cryptography system such as RSA.<BR><BR></DIV></TD></TR>
