auth: GnuPG and EasyPG Assistant Configuration

 
 Appendix A GnuPG and EasyPG Assistant Configuration
 ***************************************************
 
 If the ‘auth-sources’ variable contains ‘~/.authinfo.gpg’ before
 ‘~/.authinfo’, the auth-source library will try to read the GnuPG
 encrypted ‘.gpg’ file first, before the unencrypted file.
 
    In Emacs 23 or later there is an option ‘auto-encryption-mode’ to
 automatically decrypt ‘*.gpg’ files.  It is enabled by default.  If you
 are using earlier versions of Emacs, you will need:
 
      (require 'epa-file)
      (epa-file-enable)
 
    If you want your GnuPG passwords to be cached, set up ‘gpg-agent’ or
 EasyPG Assistant (Caching Passphrases (epa)Caching Passphrases.).
 
    To quick start, here are some questions:
 
   1. Do you use GnuPG version 2 instead of GnuPG version 1?
   2. Do you use symmetric encryption rather than public key encryption?
   3. Do you want to use gpg-agent?
 
    Here are configurations depending on your answers:
 
 1     2     3     Configuration
 Yes   Yes   Yes   Set up gpg-agent.
 Yes   Yes   No    You can’t, without gpg-agent.
 Yes   No    Yes   Set up gpg-agent.
 Yes   No    No    You can’t, without gpg-agent.
 No    Yes   Yes   Set up elisp passphrase cache.
 No    Yes   No    Set up elisp passphrase cache.
 No    No    Yes   Set up gpg-agent.
 No    No    No    You can’t, without gpg-agent.
 
    To set up gpg-agent, follow the instruction in GnuPG manual (
 Invoking GPG-AGENT (gnupg)Invoking GPG-AGENT.).
 
    To set up elisp passphrase cache, set
 ‘epa-file-cache-passphrase-for-symmetric-encryption’.
