Emacs has an interface for gunpg

keeping your secrets secret

If you want to keep your secrets secret, it is a good idea to encrypt 
your data; I usually do that for files with passwords for various 
services, banking data, and so on. Since version 23, Emacs includes a 
package called EasyPG (an interface to GnuPG) which makes this seamless 
– just make sure that you have GnuPG installed.

It's easy to use EasyPG – the only thing you need to do is adding the 
.gpg -extension to your files, and EasyPG will automatically 
encrypt/decrypt them when writing/reading. So, for example, to create an 
encrypted org-mode-file, simply visit (C-x C-f) a file with a name like 
myfile.org.gpg; emacs opens this in Org-Mode (just like any .org-file). 
When you want to save the file, emacs will ask you for a password, and 
with this same password, you can open it again. Don't forget that password!
