RSAREF help requested

[Eric Conrad <conrad@merl.com>]

I need to use RSAREF to do 3 simple things: generate a keypair, encrypt 
a file, and decrypt a file.  This is so that I can safely encrypt online
information with the public key, while keeping the private key offline.

PGP does what I want, but I can't use it due to legal reasons.

Ripem does too much (all the mail and key management stuff), and is too
complex for my purposes.

I've begun writing the C code using the RSAREF libraries to do what I 
want, but I'd rather not recreate the wheel.  Has anyone written the 
simple tools I described?
