How to Decrypt HTTP Custom File Exclusive: A Step-by-Step Technical Deep Dive

In the world of VPN tunneling, payload injection, and network bypassing, HTTP Custom has emerged as a powerful tool for Android users. It allows technical enthusiasts to create custom SSH, VPN, or proxy configurations packaged in .hc files. These files often contain sensitive authentication data, payloads, and remote proxy settings.

1. Decode base64 (if applicable)
   1. Install the required libraries: npm install crypto
   2. Capture the HTTP request: Use tools like tcpdump or Wireshark to capture the HTTP request containing the custom file.
   3. Extract the encrypted data: Extract the encrypted data from the captured HTTP request.
   4. Decrypt the data using JavaScript:
   • If the format is from an open-source client, there may be extractors or converters (search GitHub for the app name + “config” or “decrypt”).

   If key derivation uses PBKDF2: Look for PBKDF2WithHmacSHA1 or SHA256. You will need to know the iteration count and salt. how to decrypt http custom file exclusive
