Decrypt Http Custom File - How To
Most .hc files are not encrypted with military-grade AES-256. Instead, they use:
In the world of network tunneling, VPN alternatives, and internet freedom, HTTP Custom has emerged as a popular Android application. It allows users to create custom SSH, SSL, and VPN tunnels to bypass firewalls, reduce latency, or access geo-restricted content. The app uses a proprietary file format with the extension .hc (HTTP Custom file) to share server configurations, payloads, and headers.
But what happens when you receive a locked .hc file? Many creators password-protect their files to prevent leeching or unauthorized modifications. If you've forgotten the password or want to understand how the configuration works, you might need to decrypt it.
This article explores what HTTP Custom files are, how encryption works, legitimate methods to decrypt them, and the ethical and legal considerations involved.
Solution: Your password is incorrect or the encryption algorithm version differs. Try AES-256 instead of AES-128.
The story of decrypting an HTTP Custom (.hc) file is a journey into the world of VPN configuration, community-driven reverse engineering, and the constant cat-and-mouse game between app developers and power users. 1. The Mystery of the .hc File
In the world of mobile tunneling, an .hc file is the "locked box" containing a specialized VPN configuration for the HTTP Custom app. These files are created by "config makers" who package sensitive data like:
SSH/VPN Account Details: Hostnames, usernames, and passwords.
Payloads: Custom HTTP headers used to bypass network firewalls.
SNI Backhosts: Specific server names used for SSL/TLS handshaking.
To protect their work or premium servers from being copied or modified, creators "lock" these files, making them unreadable to anyone but the app itself. 2. The Mechanics of the Lock
For a long time, these files were impenetrable. However, the community discovered that the app uses specific hardcoded encryption keys to wrap the configuration data. As the app evolved, the "locks" changed. Some of the most famous keys discovered by researchers include: how to decrypt http custom file
hc_reborn_4: Used for the latest versions from the Play Store.
hc_reborn_7 and hc_reborn___7: Used for various beta and stable builds.
hc_reborn_tester_5: A legacy key often seen in older or specific test builds. 3. The Decryption "Heist"
The decryption process doesn't happen inside the app; it happens in the terminal. Tools like hcdecryptor were developed as Python scripts to crack these configurations open. The "heist" follows a specific sequence:
Clone the Gear: Users download a decryption script from repositories like HCTools.
Target the File: The encrypted .hc file is placed in the same directory as the script.
Execute the Command: Running a simple command like python3 decrypt.py encrypted.hc initiates the process.
Extract the Loot: If the key matches, the script outputs the raw configuration—revealing the hidden payloads and server credentials. 4. The Countermove: Cloud Configs
As decryption tools became common, config makers moved to more advanced protection. Instead of sharing a local .hc file, they now use HTTP Custom Cloud Configs. This method hosts the configuration on a remote server and generates a link. Because the actual file data is never stored locally on the user's device in a persistent format, it is significantly harder—if not impossible—to "decrypt" using standard local tools.
Warning: Decrypting configuration files you did not create may violate the terms of service of the config provider or the VPN service itself. How to create HTTP CUSTOM UNLIMITED FILES.
Decrying an HTTP Custom file (typically with a .hc extension) involves extracting the configuration data—such as SSH details, payloads, and proxy settings—that has been locked by the original creator to prevent tampering or unauthorized sharing. These files are used by the HTTP Custom VPN application to facilitate secure, custom tunneling. Understanding the .hc Encryption Solution: Your password is incorrect or the encryption
HTTP Custom files are generally encrypted using a specific set of keys that vary depending on the version of the application used to create them. Common decryption keys used in these tools include: hc_reborn_4 (for recent Play Store versions) hc_reborn___7 (for public beta versions) hc_reborn_tester_5 (for various testing builds) Methods for Decryption
While the official application does not provide a "decrypt" button for locked files, several community-driven tools exist for this purpose. 1. Using Python-Based Decryptors
The most reliable method is using scripts found on GitHub, such as hcdecryptor.
Setup: Clone the repository and install the required Python dependencies:
git clone https://github.com/HCTools/hcdecryptor.git cd hcdecryptor pip3 install -r requirements.txt Use code with caution. Copied to clipboard
Execution: Place your .hc file in the script folder and run: python3 decrypt.py yourfile.hc Use code with caution. Copied to clipboard
Output: The script attempts to use known keys to unlock the file and print the plaintext configuration, such as the SSH server and payload. 2. Web-Based Tools and Telegram Bots
For those uncomfortable with command-line tools, developers have created simpler interfaces:
HCDrill: A web-based version of the decryptor is available as a WIP project on GitHub, allowing users to upload files for instant decryption.
Telegram Bots: Specialized bots (like HCDrill-tg) are frequently used by the community to decrypt files shared in groups by simply forwarding the file to the bot. Why Decrypt?
Decryption is typically performed by advanced users or security researchers to: The story of decrypting an HTTP Custom (
Verify Security: Ensure the configuration is not sending data to malicious servers.
Debug Connections: Modify payloads that are no longer working with a specific ISP.
Learning: Understand how specific tunneling "tweaks" are structured to create their own configurations from scratch.
Note: Decrypting files created by others may violate the terms of service of the communities where they are shared, especially if they are intended for private use or paid access. hc files from scratch to avoid needing a decryptor? HCTools/hcdecryptor: Decryptor for HTTP Custom ... - GitHub
An HTTP Custom file is essentially a JSON-based configuration saved with custom encryption. It contains:
Example of a decrypted JSON snippet:
"server": "sg1.example.com",
"port": "443",
"username": "tunneluser",
"password": "encrypted_password",
"payload": "GET / HTTP/1.1[crlf]Host: google.com[crlf][crlf]"
Some hobbyists decompile the HTTP Custom APK using tools like JADX or Ghidra to find the hardcoded decryption routine. This is:
Because of these risks, this method is not covered in detail here.
