    Based on the crypto-js library, StatiCrypt uses AES-256 to encrypt your input with your passphrase and put it in a HTML file with a password prompt that can decrypted in-browser (client side).

    You can then upload your static html file anywhere and it'll be password protected (see how it looks).

    Obviously, pick a lengthy passphrase !


    StatiCrypt generates a static, password protected page that can be decrypted in-browser: just send or upload the generated page to a place serving static content (github pages, for example) and you're done: the javascript will prompt users for password, decrypt the page and load your HTML.

    It basically encrypts your page and puts everything with a user-friendly way to use a password in the new file.

    AES-256 is state of the art but brute-force/dictionary attacks would be trivial to do at a really fast pace: use a long, unusual passphrase!

    The concept is simple and should work ok but I am not a cryptographer, if you have extra sensitive banking data you might want to use something else :)

    Feel free to contribute or report any thought to the GitHub project !


    Staticrypt is available through npm as a CLI, install with npm install -g staticrypt and use as follow:

    Usage: staticrypt <filename> <passphrase> [options]
      --help               Show help                                       [boolean]
      --version            Show version number                             [boolean]
      -e, --embed          Whether or not to embed crypto-js in the page (or use an
                           external CDN)                   [boolean] [default: true]
      -o, --output         File name / path for generated encrypted file
                                                            [string] [default: null]
      -t, --title          Title for output HTML page
                                                [string] [default: "Protected Page"]
      -i, --instructions   Special instructions to display to the user.
                                                            [string] [default: null]
      -f, --file-template  Path to custom HTML template with password prompt.
                              [string] [default: "[...]/cli/password_template.html"]

    Example usages:

    • staticrypt test.html mypassword -> creates a test_encrypted.html file
    • find . -type f -name "*.html" -exec staticrypt {} mypassword \; -> create encrypted files for all HTML files in your directory (recursively)

    You can use a custom template for the password prompt - just copy cli/password_template.html and modify it to suit your presentation style and point to your template file with the -f flag. Be careful to not break the encrypting javascript part, the variables replaced by staticrypt are between curly brackets: {instructions}.

    ADBLOCKERS: If you do not embed crypto-js and serve it from a CDN, some adblockers see the crypto-js.min.js, think that's a crypto miner and block it.
