the passphrase you enter to encrypt.
Sorry, I'm not familiar with that encryption type. If it is explained in some document, just point me to it :-)

The explanation is too short. +++—-—-—-—-—-—-—-—-—- Symmetric key encryption In symmetric-key schemes,[3] the encryption and decryption keys are the same. Thus communicating parties must have the same key before they can achieve secret communication. —-—-—-—-—-—-—-—-—-++- Ok, my understanding from reading the above is that it uses the private side of one of the PGP key pairs already defined in the system, the one marked as default, which has a defined password to open it (the one defined when the key pair was created. Not that it uses the typed password for encryption. BUT.... That is not true. I just created a symmetric encrypted file with emacs in a virtual machine, one that I know for certain does not contain any PGP key. The file was successfully encrypted, using as password just "Hello". I transferred the file to the host, and I could open it directly it with the password "Hello". So it is not using any PGP keys at all! The password is the key. This is not what I want, certainly not. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
