PC with an Android Emulator (like LDPlayer or BlueStacks) and a packet sniffer like HTTP Toolkit or Wireshark .
There are various tools available for decrypting files, depending on the encryption method used. Some popular ones include:
If you cannot open the file, you can intercept the traffic while the app is active. the locked .hc file into HTTP Custom. Connect the VPN. how to decrypt http custom file exclusive
Run the script while HTTP Custom loads the config, and the plaintext configuration will be printed to the console.
While there are community-made "sniffers" or third-party decryption tools (often shared in Telegram groups or developer forums), these methods are:
If you're dealing with an HTTPS (which is HTTP over TLS/SSL) connection and need to decrypt a file that was transferred securely, the process might involve capturing the traffic and then using the appropriate keys and certificates for decryption. : Run the application inside a rooted Android
Java.perform(function () let TargetClass = Java.use("com.vpn.httpcustom.utils.ConfigParser"); // Example class name TargetClass.decryptMethod.implementation = function (encryptedData) console.log("[*] Decryption method intercepted!"); // Execute the original decryption logic let decryptedResult = this.decryptMethod(encryptedData); // Print the plain-text configuration payload to the console console.log("[+] Decrypted Payload: " + decryptedResult.toString()); return decryptedResult; ; ); Use code with caution.
Leo discovers that standard file managers or text editors cannot read locked .hc files. After some searching, he finds a specialized tool on GitHub called HCTools/hcdecryptor , designed specifically for this purpose. 2. Running the Decryptor Leo follows the instructions provided by the community:

If you’re a creator and want to protect your .hc files from the methods above:
The next 128 bytes were an RSA-OAEP encrypted symmetric key. Without the private key, he was stuck—until he remembered the flaw. VeilFlow’s “exclusive” mode had a backdoor for debugging: if the HTTP Cookie header contained debug=true , the server would echo the handshake in plaintext. The same logic was baked into the file format. Hidden after the RSA block, four null bytes, then a plaintext XOR keystream.
The HTTP Custom Android application utilizes the .hc file extension to store secure VPN configurations. Security researchers and network administrators often need to decrypt these exclusive configuration files to audit payloads, verify server endpoints, or troubleshoot connectivity issues. This technical guide outlines the architecture of .hc files and the methodologies used to analyze and decrypt them. Understanding HTTP Custom Configuration Architecture
When a config creator exports a file in HTTP Custom, they can choose to it. This prevents other users from: Viewing the SSH/VPN account details. Seeing the SNI (Server Name Indication) or Host.
