Decrypting these files is not straightforward, but the open-source community has developed several effective methods. The decryption process relies on extracting the configuration data by using the same cryptographic keys that the app itself uses.
What are you using to perform the decryption (Windows, Linux, or Android)? What version of the HTTP Custom app created the file?
Java.perform(function () var Cipher = Java.use('javax.crypto.Cipher'); Cipher.doFinal.overload('[B').implementation = function (bytes) var result = this.doFinal(bytes); var util = Java.use('android.util.Log'); // Convert the decrypted byte array to a readable string var decryptedString = ByteToString(result); console.log("[+] Decrypted Payload/Config Data: " + decryptedString); return result; ; ); Use code with caution.
Before you attempt to decrypt any HTTP Custom files, please consider the following: how to decrypt http custom file exclusive
# If the file has 'Salted__' header, extract salt and use custom KDF if ciphertext[:8] == b'Salted__': salt = ciphertext[8:16] # You'd need to re-derive key using EVP_BytesToKey (OpenSSL) # Skipping for brevity - see step 4 for OpenSSL method
: The first step in decrypting a file is to know how it was encrypted. Common encryption algorithms include AES (Advanced Encryption Standard), RSA, and DES (Data Encryption Standard), among others.
Decrypting configuration files should only be done for files you own or have explicit permission to analyze. The techniques and tools described here are for educational purposes and to help users recover their own lost configurations. Decrypting these files is not straightforward, but the
Once the algorithm (usually AES/CBC/PKCS5Padding or AES/ECB ) and keys are extracted, you can write a Python script to automate the decryption.
An .hc file is essentially an encrypted VPN configuration profile used primarily by the HTTP Custom Android app, also known as an AIO Tunnel. These files contain important networking rules, including:
Navigate through the decompiled Java classes (often obscured by ProGuard obfuscation, such as a.b.c.class ). Look for a 16, 24, or 32-character string assigned near the encryption methods. This string, alongside the Initialization Vector (IV), is used to decrypt the .hc file byte stream. Step 4: Run a Decryption Script What version of the HTTP Custom app created the file
While HCDecryptor and its ports (JavaScript/Node.js) are the most common, other decryption utilities exist on platforms like GitHub. However, they are often derived from the same core logic. Always ensure you are using tools from reputable sources to avoid malware.
