StatiCrypt uses AES-256 to encrypt your HTML file with your passphrase and return a static page including a password prompt and the javascript decryption logic that you can safely upload anywhere (see what the page looks like).

This means you can password protect the content of your public static HTML file, without any back-end – serving it over Netlify, GitHub pages, etc. (see the detail of how it works).

You can encrypt a file online in your browser (client side) at https://robinmoisson.github.io/staticrypt, or use the CLI to do it in your build process.

CLI

Installation

Staticrypt is available through npm as a CLI, install with

You can then run it with npx staticrypt .... You can also install globally with npm install -g staticrypt and then just call staticrypt ....

Examples

These will create a .staticrypt.json file in the current directory, see the FAQ as to why. You can prevent it by setting the --config flag to “false”.

Encrypt a file: Encrypt test.html and create a test_encrypted.html file (add -o my_encrypted_file.html to change the name of the output file):

staticrypt test.html MY_PASSPHRASE

Encrypt a file with the passphrase in an environment variable: set your passphrase in the STATICRYPT_PASSWORD environment variable (.env files are supported):

# the passphrase is in the STATICRYPT_PASSWORD env variable
staticrypt test.html

Encrypt a file and get a shareable link containing the hashed password – you can include your file URL or leave blank:

find . -type f -name "*.html" -exec staticrypt {} MY_PASSPHRASE -o {} ;

find . -type f -name "*.html" -not -name "*_encrypted.html" -exec staticrypt {} MY_PASSPHRASE ;
