VB6: RSA keypair generation, encryption and decryption

I need 3 basic apps written to make RSA relatively easy to incorporate in my other software. It's essentially just one program, but broken into its 3 main components for brevity. All 3 tools must be written in Visual Basic 6 (_not_ VB.NET), and must use the Windows CryptoAPI functions - no other 3rd party components are to be used. App 1 - Generates a new random keypair (public + private keys) of at least 128bits in size, preferably 256bit. App 2 - Encrypts a file using a hard-coded public key App 3 - Decrypts the file using the related hard-coded private key
