Notepad++ 7.5.3 – Encrypt text files


   This tutorial will show you how to use the NppCrypt plugin provided by Notepad++ to encrypt your documents so that you don't have to worry quite so much about your documents being read without your permission.


The instructions presented within this tutorial should not damage your install but should be followed in order, or you could loss data.  This tutorial is based on the official 7.5.3 build of Notepad++.



1.   Download and Install the latest Notepad++ build.

  • Official build 7.5.3 can be found HERE.


From here forward there are two options.  The first can be used if the “Plugins Manager” is displayed under “Plugins > Plugin Manager > Show Plugin Manager” from the main menu of Notepad++.  The second must be used if the option is not present.  (During this install I had to use the second option.



1.   Open Notepad++.

2.   Launch the plugin manager by going to Plugins > Plugin Manager > Show Plugin Manager.

3.   Select NPPCrypt from the list and click Install.

4.   Allow Notepad++ to restart after the installation finished.



1.   Download the required files from GitHub HERE or the pre-merged file found under “Downloads” from our site HERE.

  • From the GitHub site, you will need the main file (Select the Clone or Download link) and the dll file found lower on the page under “ from github:”.
  1. For the split version from github, extract the “nppcrypt-cryptopp” folder to C:\Program Files\Notepad++\plugins\Config and the nppcrypt.dll file to C:\Program Files\Notepad++\plugins.
  2. For the pre-merged version from our site, extract the “plugins” folder to C:\Program Files\Notepad++.

2.   Open Notepad++ and verify that NppCrypt is present under Plugins > NppCrypt.



1.   Highlight the text you want encrypted then go to Plugins > NppCrypt > Encrypt.

2.   Select the cipher and mode you want to use, input a password, then confirm the password.



1.   Highlight the text you want decrypted then go to Plugins > NppCrypt > Dencrypt.

2.   Input your password and everything will go back to normal.
