I just 'ported' (euphemism for minor modifications) some
code lingering on the web for fun and voila: MD5 on RCX
is up and running (lejos). If anyone's interested, I can
post the code.

Definitely post it! Better than that, how about sending me the code and I'll
add it to our robots section as a unique demonstration.

It would be a nice project for somebody to implement bignums on leJOS,
the API is in java.math.BigInteger .
work in progress, but it's probably not going to be of any use
for implementing, say, RSA. (memory, no GC,...) (maybe when restricting
BigInt just to what is needed for RSA computation...)

Shouldn't be a problem. Most of the source code in the official Sun package
is easy to port to leJOS. BigInteger probably has a lot of native code for
speed though. People are sure going to wonder "Why did they make BigInteger
for robot projects?" :)

  MD5 available (was: RCX as a PGP engine)
 
I just put my java MD5 port for lejos on the web: (URL) for the popups, Tripod....) It's a terrible hack, but thanks to that memory footprint is low and it does not leak! Let me know if you find it useful. Have fun, Bart. (23 years ago, 7-Apr-02, to lugnet.robotics.rcx.legos, lugnet.robotics.rcx.java)
