Decrypting an exclusive HTTP Custom file is a multi-step reverse engineering process that requires knowledge of cryptography, Android internals, and scripting. While the base protection is AES encryption with a semi-static key, newer versions introduce device binding and dynamic keys that make decryption non-trivial.

For the average user, attempting to decrypt an exclusive file is not recommended unless you are the file owner or have explicit permission. Instead, request an unencrypted version from the creator.

However, for security researchers and developers, understanding this process helps improve the robustness of your own configuration protection mechanisms.

Remember: With great decryption power comes great responsibility. Always respect digital rights and intellectual property.

While the specific decryption algorithms are proprietary to the app's developers, the "decryption" of these files is a common topic in cybersecurity and network research circles. The Purpose of Configuration Locking Developers "lock" or encrypt .hc files for several reasons:

Privacy: To hide the SNI (Server Name Indication) or host used to gain free internet access.

Monetization: To prevent users from seeing the private servers they are paying for.

Integrity: To ensure users don’t change the payload and break the connection. How Decryption Works (Conceptual)

Decrypting an exclusive file isn't about "cracking" a password in the traditional sense; it’s about intercepting the data at the moment the application reads it.

Memory Dumping: When you import an .hc file into the HTTP Custom app, the app must decrypt the file internally to use the settings. Advanced users use tools like GameGuardian or Frida to dump the phone's RAM while the app is running. By searching for specific strings (like "ssh" or "payload"), they can find the decrypted configuration in plain text.

Decompiling the APK: Some researchers decompile the HTTP Custom APK using tools like jadx or APK Easy Tool. By analyzing the Java/Kotlin code, they attempt to find the "Salt" or "Secret Key" used by the app’s encryption function. Once the key is found, a simple script can be written to decrypt any .hc file.

Third-Party "Sniffers": There are modified versions of VPN apps or specialized "packet sniffers" (like e-Proxy or Canary) designed to sit between the app and the network. These tools capture the decrypted payload as it is sent to the server. Tools Often Used

NP Manager / MT Manager: File managers used on Android to modify APKs or view protected files.

Hex Editors: Used to view the raw data of the .hc file to identify the header format.

Virtual Machines: To run the app in a controlled environment where memory can be easily inspected without root restrictions. Ethical and Legal Considerations

It is important to note that decrypting someone else’s configuration file often violates the Terms of Service of the application and may infringe on the "Intellectual Property" of the configuration creator. In many communities, "sniffing" or "unlocking" files is frowned upon as it can lead to the "burning" (blocking) of the hosts and payloads used to provide internet access. Conclusion

Decrypting an HTTP Custom exclusive file is a cat-and-mouse game between app developers and reverse engineers. While tools like memory dumpers and APK analyzers make it possible, the best way to learn how these configurations work is to study SSH tunneling and HTTP headers from scratch rather than reverse-engineering the work of others.

Decrypting custom files, especially those transferred over HTTP (Hypertext Transfer Protocol), involves understanding both the method used for encryption and the specific tools or software that can handle such encryption. HTTP itself does not encrypt data by default, making it essential to use other methods for securing data during transmission. However, when referring to decrypting custom file formats that have been encrypted, here are general steps you might follow, assuming you have control over both the encryption and decryption process:

Open the exclusive .hc file in a hex editor (HxD). Look for patterns:

Most exclusive files from HTTP Custom start with a long Base64 string without a standard file signature.

HTTP Custom is one of the most powerful tools for tunneling, SSH, VPN, and custom proxy configurations on Android devices. Users frequently encounter files with the .hc extension—colloquially known as "HTTP Custom files." These files allow users to import pre-configured settings for SSH, SSL, WebSocket, or payload injections.

However, many advanced users and developers hide their configurations by converting standard files into "Exclusive" or "Encrypted" files. When you try to open an Exclusive file with a text editor, you see only garbled data or Base64-encoded ciphertext. This article walks you through the methodology, tools, and step-by-step process to decrypt an exclusive HTTP Custom file.

If you are a content creator who wants to protect your HTTP Custom configs, apply these countermeasures:

Before attempting decryption, you must understand what an .hc file actually contains.

Decrypting a custom file sent over HTTP involves understanding the encryption method, obtaining the decryption key, and using the appropriate tools. Always ensure that you are legally and ethically allowed to perform the decryption. If you're dealing with a specific encryption method or tool, consult the relevant documentation or seek help from cybersecurity professionals.

Decrypting HTTP Custom (.hc) "Exclusive" files involves reversing the application's internal encryption used for VPN configuration exports. These files are typically locked by creators to hide sensitive server details, such as SNI bug hosts, SSH accounts, or proxy settings.  Understanding the .hc Format 

The HTTP Custom app (available on Google Play) exports configurations as .hc files. "Exclusive" files are versions of these configurations that have been locked with specific keys or linked to a "Cloud Config" to prevent unauthorized viewing of the underlying payload and server data.  Known Decryption Methods 

Community-driven tools often rely on identifying the static encryption keys used by different versions of the app.  1. Automated Tools (Python) 

The most common approach uses scripts like HCTools hcdecryptor or DjKadex hcdecryptor. 

Requirements: A Python 3 environment and the pycryptodome library. Process: Place the .hc file in the script directory. Run the command: python3 decrypt.py yourfile.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).  2. Web-Based Decryptors 

For users without a Python environment, tools like HCDrill provide a browser-based interface to upload and decrypt .hc files directly.  Common Decryption Keys 

Decryption success often depends on using the correct key for the file's original version:  App Version  Likely Key Latest Play Store hc_reborn_4 Public Beta (2.6) hc_reborn___7 Version 2.4 hc_reborn_7 Version 2.5 hc_reborn_tester_5 Limitations 

Cloud Configs: Files protected via the "Cloud Config" method may not be decryptable using standard key-based scripts, as the configuration is often fetched dynamically or tied to server-side authentication.

Custom Keys: If a creator uses a completely unique, non-standard key or a modified version of the app, public decryptors will fail.

Legal/Ethical: Decrypting files created by others may violate the terms of service of the original configuration provider or the HTTP Custom app itself.
