[Wlug] encrypted files

I have a question about using gpg to encrypt private files on my system. Which encryption is the preferred for file storage? Symmetric? (gpg -c) This seems the most secure and flexible, but I'm getting tired of typing the key so often. Public/private? This seems enticing, because encryption is done without needing to type a password. However, the keyring is on the same system as the encrypted file, and thus is vulnerable. Thanks, Bill
