Shouldn't this be just the opposite -- local10 should encrypt the file with his recipient's public key, and then his recipient can unencrypt it with his (the recipient's) private key? The way you described would be for use as a signature, to prove that local10 actually sent the file -- anybody with the public key can unencrypt demonstrating that local10 inititated the file.
