HTTP Custom files contain sensitive connection parameters. To protect this data from tampering and unauthorized viewing, the application employs encryption layers before exporting the configuration. : .hc
The tool attempts to decrypt the file using a list of hardcoded keys associated with various app versions (e.g., hc_reborn_4 , hc_reborn_7 ).
The encryption keys and logic are compiled into the HTTP Custom Android application package (APK). Obtain the official HTTP Custom APK file. Load the APK into .
Config creators spend hours finding working SNIs and payloads. Decrypting and re-sharing their work without permission is generally frowned upon in the tunneling community.
Running this hook prints the actual key directly onto the debugging console, bypassing any code obfuscation implemented by the developer. Method 3: Cloud Extraction and Web-Based Alternatives how to decrypt http custom file exclusive
: Write a Frida script to hook into the application's decryption method.
The HTTP Custom Android application utilizes the .hc file extension to store secure VPN configurations. Security researchers and network administrators often need to decrypt these exclusive configuration files to audit payloads, verify server endpoints, or troubleshoot connectivity issues. This technical guide outlines the architecture of .hc files and the methodologies used to analyze and decrypt them. Understanding HTTP Custom Configuration Architecture
You will likely see the SNI (the host used to trick the network) and the Remote Proxy IP . Since these are sent in the clear during the initial handshake, they are easy to extract. 3. Decrypting the .hc via Python Scripts or Termux
Open your terminal or command prompt and execute the following commands to pull down the automated script and install dependencies: HTTP Custom files contain sensitive connection parameters
The encryption key is derived from a combination of:
The payload might be obfuscated, making it hard to read even if decrypted. 3. How to Unlock/Decrypt HTTP Custom Files (Methods)
Trigger the connection. The Frida console will output the plain text payload or the secret keys as they pass through the device's RAM. Method 3: The Runtime Payload Sniffing Bypass
You can now:
Would you like help understanding how HTTP tunnel configurations work so you can build your own from scratch instead?
// Frida script snippet to catch HTTP Custom AES keys Java.perform(function () var SecretKeySpec = Java.use('javax.crypto.spec.SecretKeySpec'); SecretKeySpec.$init.overload('[B', 'java.lang.String').implementation = function (key, cipher) var logString = ""; for (var i = 0; i < key.length; i++) logString += String.fromCharCode(key[i]); console.log("[*] Cipher Detected: " + cipher); console.log("[*] Intercepted Key: " + logString); return this.$init(key, cipher); ; ); Use code with caution.
To ensure successful decryption of HTTP custom files exclusively:
