Before attempting decryption, you must understand what an .hc file actually contains.
“HTTP Custom” often refers to configuration or profile files used by VPN/tunneling apps that implement HTTP-based payloads, custom headers, or obfuscation. These files may be plain text (config) or packaged/encrypted by app-specific formats. Before trying to decrypt, determine whether the file is actually encrypted or simply encoded/packed.
Open the exclusive .hc file in a hex editor (HxD). Look for patterns: how to decrypt http custom file exclusive
Most exclusive files from HTTP Custom start with a long Base64 string without a standard file signature.
The first step is to identify how the files are encrypted. Common methods include: Before attempting decryption, you must understand what an
HTTP Custom exclusive files use one of two schemas:
| Version | Method | Key source |
|---------|--------|-------------|
| v19–v22 | AES-256-CBC, static key | Embedded in libhttpcustom.so |
| v23+ | AES-256-CBC, dynamic key | device_id + package_name + salt | Most exclusive files from HTTP Custom start with
Remember that HTTP Custom updates frequently. A method that works today may be patched tomorrow. Always check GitHub or XDA Developers forums for the latest decryption tools and techniques.
There are various tools available for decrypting files, depending on the encryption method used. Some popular ones include:
