The docstring should prominently say that this var doesn't work with gpg2 because gpg2 does not let Emacs cache the passphrase (IIUC we can't make this var effective without changes in gpg2). > I didn't get the question correctly, then. > Look at the matrix of (info "(epa) Caching Passphrases"), check when a > user is suggested to "set up elisp passphrase cache". That repeats the fact that symmetric encryption is handled differently but still doesn't help me understand why. Stefan
