In any case, here's a little function to decrypt some saved mail. (defun decrypt-saved-message (file &optional save) "Decrypt a plaintext mail FILE. With prefix arg SAVE, save the decrypted contents." (interactive "F\nP") (require 'epa-mail) (let ((buffer (get-buffer-create (format "%s *decrypted*" (file-name-nondirectory file))))) (pop-to-buffer buffer) (insert-file-contents file) (while (re-search-forward "-----BEGIN PGP MESSAGE-----$" nil t) (setq armor-start (match-beginning 0) armor-end (re-search-forward "^-----END PGP MESSAGE-----$" nil t)) (unless armor-end (error "Encryption armor beginning has no matching end")) (goto-char armor-start) (let* ((context (epg-make-context 'OpenPGP)) (decrypted (epg-decrypt-string context (buffer-substring armor-start armor-end)))) (delete-region armor-start armor-end) (insert decrypted))) (when (or save (y-or-n-p "Save mail in decrypted form?")) (write-file file)))) It can be used interactively, or if you want to decrypt a bunch of saved mails you can call it from lisp with a second argument: (dolist (f '("~/mail1" "~/mail2" ...)) (decrypt-saved-message f t)) Surely this can be hacked a bit to make gnus decrypt the mail before saving... -- Jamie --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQFNBAEBCAA3FiEElxJbPtj12sn/xkPXc0qyklu3X7MFAl7gOYYZHGJlYXJkc2xl ZWphbWllQGdtYWlsLmNvbQAKCRBzSrKSW7dfs4XjB/9beyU9v2sxdKvQ1m/ok/yx 1NXbv3rIk5fTYupw8q4uDWMn++zsrNVvJBl3vWCUQLCd/0pylHs/9KkLTG8c1MRC lwO6W6pmTiZST8hoZc1P4ewjAW/LkI5eeJkGxGQE2SdbTRMo5PYgwIluMhQP08fE T0zunmU0KFNfyTKSESNLLGjBycttXUQI4yZQIutLPn0ND8Ge8b4YyGeVrTB+9Stz L+Segc/dDdVIzUfz75D6ffkdUkaelKKRIzbWPfUWg/Fgr0DiipZtPmG+qehAvmSp eSlhoNpH7oHsS1aOiowOzZlNhrO0Wn75Jc8wFQzmiTa0CDmUukU6QRd42T9Ox4TB =IFSm -----END PGP SIGNATURE----- --=-=-=--
