Hi!
You may encrypt/decrypt using a private key (yours), or encrypt/decrypt using the public key of another party. The latter is commonly done when verifying signatures, though encrypting with another's public key is a common enveloping technique.
Hm, I still don't get the point in having four functions. Mathematically seen there are only two different actions I can do: either raise the 'message' x to the power of the public exponent or to the power of the private exponent. Right?
