Encrypt-to-HTML

Simple implementation of files embedding to HTML as a blob, with AES-CBC Encryption.

Features

• Embeds any file type into an HTML as a Base64-encoded blob.
• Provides AES-CBC encryption for the embedded file.
• Embeds CryptoJS in the HTML for offline decryption.
• Includes password verification functionality using random test data.

Requirements

• Python 3
• Crypto (pip install pycryptodome)
• Jinja2 (pip install Jinja2)

Usage

python3 encrypt-to-html.py <input_file> <key> [output_file] [output_template]

• <input_file>: The file you want to encrypt and embed.
• <key>: The encryption key. It is hashed to a 256-bit key using SHA256.
• [output_file]: Optional. The output HTML file. If not provided, the output file will be named as <input_file>-enc.html.
• [output_template]: Optional. A custom Jinja2 HTML template file to use instead of the default embedded template.

Note

The generated HTML file uses the CryptoJS library for decryption. This library is embedded in the HTML, ensuring the decryption process can be done offline.

Example

To encrypt and embed a file named example.txt with the key example_key, you would run: python3 Encrypt-to-HTML.py example.txt example_key

This will create an HTML file named example.txt-enc.html containing the encrypted and embedded file, which can be decrypted using the provided key.
