The User's Library had an implementation of RSA for the HP-16C, and it's on the Museum "DVD", from memory. However, a man has to know his limits. . .

I get my students to implement a DES-like cipher in Java; the pain of doing that kind of bit-fiddling in a language that does not support unsigned integers gives them a new appreciation of the virtues of C. I would expect similar pain here.
