Actually, for *just that* and nothing else, you're probably better off
using a message digest algorithm like SHA-1. It's lighter weight and
far less complex to implement.
Use public key signing to verify that a message was signed by the
holder of the private key, not just that it wasn't changed in
transport. For that, message digests are sufficient.
