Emacs Secracy !

Making emacs secret keeper : emacs have EasyPG which is a emacs interface for managing GnuPG .

(require 'epa-file)
(epa-file-enable)

Now Emacs encrypt and decrypt all files with extension .gpg When you save the encrypted file it asks for the key , this can be avoided by setting a local variable for file

-*- epa-file-encrypt-to: ("your@email.address") -*-

Now we just add this to our journal and change the journal.org to journal.org.gpg , That makes our journal encrypted for good reasons. To encrypt a file add the above line and save the file as a .gpg and you are good to go We can also encrypt a region with epa-encrypt-region

to decrypt select the region and call epa-decrypt-region it replaces the plain text in there

Mark all the files in dired and call epa-dired-do-encrypt to encrypt all the files

There is also a Org-Crypt This enable to encrypt all the org having a specific tag such as crypt to automatically encrypt

(require 'org-crypt)
(org-crypt-use-before-save-magic)
(setq org-tags-exclude-from-inheritance (quote ("crypt")))

(setq org-crypt-key nil)
  ;; GPG key to use for encryption
  ;; Either the Key ID or set to nil to use symmetric encryption.

(setq auto-save-default nil)

This sets up org-crypt with tag crypt This is very convenient if we only want to encrypt only a section of a org file

Encrypt Everything!! Emacs Rocks!!
