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.
Decryption of HTTP Custom files—specifically those with the .hc extension—is a topic often sought by users looking to understand the underlying configurations, account details, or proxy settings within a shared VPN config. HTTP Custom is a popular AIO (All-in-One) tunnel tool for Android that allows users to modify requests and bypass firewalls.
While many files are "locked" by creators to protect their private servers and methods, there are several technical approaches used to "unlock" or decrypt these exclusive files. Understanding the HTTP Custom (.hc) Format how to decrypt http custom file exclusive
Before attempting decryption, it is important to understand what a .hc file actually is. These files are essentially encrypted archives containing: Remote Proxy Settings: IP addresses and ports. Payload Strings: The HTTP headers used to "bug" a network.
SSH/V2Ray/Trojan Credentials: Usernames, passwords, and private keys.
Hardware ID (HWID) Locks: Constraints that limit the file to specific devices.
The encryption is used by "ehi" or "hc" creators to prevent "payload sniffing," which is the act of stealing a working connection method to redistribute it or claim it as one's own. Methods for Decrypting HTTP Custom Files
There are three primary ways researchers and enthusiasts approach the decryption of these files. 1. Using Modified APKs (Sniffers)
The most common method involves using a "modded" version of the HTTP Custom app itself.
How it works: Developers modify the original APK to log the decrypted configuration to a text file or a Toast message the moment the "Connect" button is pressed.
The Process: You install the modded APK, import the "exclusive" .hc file, and hit connect. The app must decrypt the data internally to establish a connection; the mod simply intercepts that data before it is sent to the VPN core. 2. Virtual Machine and Packet Sniffing
If you cannot find a modded APK, you can use a controlled environment to see what the app is doing.
Tools: PC with an Android Emulator (like LDPlayer or BlueStacks) and a packet sniffer like HTTP Toolkit or Wireshark.
The Process: By routing the emulator's traffic through a proxy on your PC, you can sometimes capture the decrypted payload headers as they are sent to the remote server. Note that if the SSH connection is encrypted, you will only see the initial HTTP handshake. 3. Logcat Inspection Android's system log (Logcat) often contains clues.
The Process: Connect your phone to a PC via ADB (Android Debug Bridge). Run the command adb logcat. While the log is running, open HTTP Custom and try to connect the file.
What to look for: Some versions of the app or the underlying binaries might print configuration errors or status updates to the log that include snippets of the payload or the remote proxy IP. Bypassing "Exclusive" Restrictions
"Exclusive" files often come with extra layers of protection beyond simple encryption. While the specific decryption algorithms are proprietary to
HWID Unlocking: If a file is locked to a specific Hardware ID, the app will refuse to decrypt it unless your device ID matches. Decrypting these requires "hooking" the app using LSPosed or Xposed Framework to spoof your device's ID to match the one expected by the file.
Expiry Dates: Some files are hardcoded to stop working after a certain date. Decrypting these usually involves changing the system clock or patching the app's internal "checkDate" function. Tools Required for Decryption Research
If you are looking to dive deeper into configuration analysis, ensure you have these tools ready:
NP Manager or MT Manager: Advanced file managers for Android that allow you to view and edit XML and DEX files within APKs.
APKEditor: Useful for modifying app permissions or injecting small scripts.
Hex Editors: For analyzing the raw byte structure of the .hc file to identify the encryption algorithm (often AES or Base64 variants). Ethical and Legal Considerations
It is vital to remember that decrypting a file created by someone else often goes against the "Terms of Service" of the community that shared it.
Respect Creators: Many creators spend hours finding working "bugs" or paying for high-speed private servers.
Security Risk: Downloading "HTTP Custom Decryptor" apps or modded APKs from unknown sources is highly dangerous. These are often used as "Trojan Horses" to steal your own data or install malware on your device.
💡 Pro Tip: Instead of trying to decrypt locked files, focus on learning how to create your own payloads using Open Source SNI host lists. This ensures your connection is secure and gives you full control over your privacy.

Decrypting HTTP Custom (.hc) files that are "exclusive" (locked by creators) is typically done to reveal the underlying configuration, such as SSH details or payloads. This process involves using specialized scripts designed to bypass the app's internal locking mechanisms. How Decryption Works
HTTP Custom uses specific encryption keys that vary by app version to lock
files. Developers in the community create "decryptors"—often Python-based scripts—that apply these known keys to unlock the files. Tools Required : Most users utilize scripts like the hcdecryptor on GitHub Decryption Keys
: The effectiveness of these tools depends on having the correct key for the version the file was created in. Common keys include: hc_reborn_4 (standard Play Store version). hc_reborn___7 (beta version 2.6). hc_reborn_7 (version 2.4). The Step-by-Step Process Environment Setup : Install Python 3 and clone a decryptor repository from Install Dependencies : Use a command line to run pip install -r requirements.txt within the tool's folder. Run Decryption : Place your file in the tool's directory and execute: python3 decrypt.py yourfile.hc Review Output
: If successful, the script generates a readable text file containing the SSH host, username, password, and any custom payloads used to bypass network restrictions. Risks and Ethical Considerations Security Risks
: Many configuration files are distributed as "unlocked" or "cloud-locked" to protect the creator's premium accounts. Decrypting these may violate the creator's terms of use.
: Be cautious when using third-party decryption scripts, as they may contain malicious code. Always review the source code on platforms like before running them.
There are various tools available for decrypting files, depending on the encryption method used. Some popular ones include:
Before attempting decryption, you must understand what an .hc file contains. HTTP Custom uses a proprietary container format that bundles:
When a creator sets a file as Exclusive, HTTP Custom applies AES-256-CBC encryption to the configuration block. The encryption key is derived from:
Without the correct key, the configuration remains scrambled. However, because the app must decrypt it at runtime, the key is recoverable through memory inspection or reverse engineering the APK.
A standard HTTP Custom file is essentially a JSON-based configuration compressed or encoded in Base64. It may contain:
When saved normally, you can rename file.hc to file.zip or file.json and view its contents.
