Correct. If I'm sending a message that I want protected, I hash the
contents with something like SHA-1. I encrypt this hash with my
private key and attach the encrypted hash to the document.
Recipients can then compute their own hash of the document, decrypt
the attached, encrypted hash usi
Gotcha. The public key does not "generate" the key. I'm going to walk
through the process again, so please bear with me.
I'm going to send you a message.
GPG creates a random key from a source of entropy such as /dev/
random. This key is used in a symmetric cipher such as AES128 to
encrypt

By definition of symmetric encryption, you must use the same key to
decrypt that was used to encrypt. I'm not sure what you're really
asking.
When you say "public key is used to generate symmetric key" you lost
me. Symmetric keys are typically just random numbers pulled from /dev/
random o

Why can't I use the same (symmetric) key I used to encrypt (public key
is used to generate symmetric key that the corresponding private key
can calculate) to decrypt?
