If successful, open the extracted files (often a JSON file or plain text file named 'payload' or 'config') in a text editor to view the contents. Method 3: Reverse Engineering the HTTP Custom App
An .hc file is not a complex proprietary binary format. It is a text-based configuration file wrapped in encryption layers.
HTTP Custom is a popular Android VPN client used to secure internet traffic, bypass censorship, and access free internet resources using custom configuration files. These files carry the .hc extension. Often, configuration creators lock or set these files to "Exclusive" to protect their payload settings, server SNI (Server Name Indication), proxy details, and intellectual property. how to decrypt http custom file exclusive
Decryption involves bypassing these constraints to read the plain text config. Method 1: Using HC Decryptor Tools (GitHub)
Open the APK in on your computer or MT Manager on Android. Decompile the Java source code ( classes.dex ). Step 2: Search for Encryption Keywords Use the global search function in your decompiler. Search for strings like: AES/CBC/PKCS5Padding SecretKeySpec Base64.decode crypto If successful, open the extracted files (often a
Prevent users from stealing premium private server credentials.
Once the key and initialization vector (IV) are found, write a short Python script using the pycryptodome library to decrypt the .hc file directly on your PC. Method 3: Using Third-Party Decrypter Apps HTTP Custom is a popular Android VPN client
Decrypting an HTTP Custom exclusive file requires extracting the cryptographic keys used by the application and replicating the decryption algorithm. 1. Reverse Engineer the APK
For users without a Python environment, tools like HCDrill provide a browser-based interface to upload and decrypt .hc files directly.
Warning: Downloading third-party decryption tools from untrusted forums poses significant security risks, including malware infection or credential theft. Troubleshooting & Protection Mitigations
The most effective way to decrypt these files is by using the hcdecryptor tool available on GitHub. This Python-based script is specifically designed to handle various versions of .hc file encryption.
