Use Emacs to encrypt files

For some private files, such as accounts and passwords, it is easy to forget if you do not need to write them down. However, you always feel a little uneasy when writing them down with common files, what if my computer is lost one day?

Emacs supports file encryption. In general, the following methods are useful:

The simplest possible is the Ange-crypt package:
Set the followingCodeAdd to the. emacs file

(Load <span style = "color: # ffa500;"> "Ange-crypt" </span>)

Or run the M-x Ange-crypt-mode command to start this mode.

Easypg should be easy to use. There are also discussions on emacswiki:
Easypg is easy to install. Put the following code in the. emacs file:

<Br/> (require 'epa-file) <br/> (EPA-file-enable) <br/>

In this way, to open or save a file suffixed with. GPG, emacs will prompt you to enter a keyword for encryption.

The following describes some problems that may occur when easypg is used:

If you want to enter the corresponding mode when opening an encrypted file with the. GPG suffix, you only need to add. GPG as the suffix of a common file to the end of a common file name. For example, a file using org mode should have been named test.org. Now I want to encrypt it through Emacs, so I can save it as test.org. GPG, so that the next time you open the file, emacs will automatically enter the corresponding org mode.

If the following error is prompted when easypg is used
