I'm not sure if signing involves the Private Key.The previous example you were having problems with was encrypted, after which it was PGP-clearsigned. This is NOT standard procedure. Rather standard procedure is to BOTH sign and encrypt in one operation. As a general rule, with very few exceptions, you NEVER SIGN ANYTHING. The reason for this is a property possessed by valid signed messages known as non-repudiability. Once the signature on a signed message verifies, it is afterwards impossible to disavow it as a forgery. For example, if you were so unwise as to sign a message sent to a vendor rgarding an order, and this message were somehow to be intercepted, you would not be able to disavow the message as a forgery. Encrypting a message only requires having someone's public key. Signing, on the other hand, requires the private key and passphrase.
