I always use VIM any single day of my life starting from 1994, and I did not realize that it’s now possible to encrypt and decrypt files with it without using gnupg! This is one of the reasons why I love vim so much: there are always things that you can learn from it!
So, I’ll now show you how to use vim to encrypt and decrypt your text files.
We can start creating a new encrypted text file with the command below:
# vim -x encryptedfile.txt Enter encryption key: Enter same key again:
Once you’ve entered an encryption key (WARNING: don’t forget it or you will lose your clear text data forever!!!) you can use vim as always, write your clear text data, save and quit.
# file encryptedfile.txt encryptedfile.txt: Vim encrypted file data # cat encryptedfile.txt VimCrypt~03!�- � ��[�v��>P��(�%
So, your file is now encrypted. To recover access to your clear text data, just open the file back with vim using the correct passphrase you used to create your file:
# vim encryptedfile.txt Need encryption key for "encryptedfile.txt" Enter encryption key:
You could also decide to change your passphrase or encrypt a clear text file, using the :set key=pwd vim command, like this:
:set key=mystrongpasswordyou'llneverfind :wq # file encryptedfile.txt encryptedfile.txt: Vim encrypted file data
If you want to decrypt the file and save it clear text, just use an empty key with the :set key= command, after you opened the encrypted file with the correct passphrase:
:set key= :wq # file encryptedfile.txt encryptedfile.txt: ASCII text
So, this way you can create an encrypted file protected with a passphrase, get read/write access to the encrypted file, decrypt the file to clear text and change the passphrase.
Hope you all will enjoy this like me!!
