How To Decrypt Http Custom File Exclusive →

Many “HTTP Custom” apps use either symmetric encryption (AES) or custom obfuscation and may bundle a known header. Steps:

A. Look for headers/markers

B. Research the app/format

C. Try known tools

HTTP Custom is one of the most powerful tools for tunneling, SSH, VPN, and custom proxy configurations on Android devices. Users frequently encounter files with the .hc extension—colloquially known as "HTTP Custom files." These files allow users to import pre-configured settings for SSH, SSL, WebSocket, or payload injections. how to decrypt http custom file exclusive

However, many advanced users and developers hide their configurations by converting standard files into "Exclusive" or "Encrypted" files. When you try to open an Exclusive file with a text editor, you see only garbled data or Base64-encoded ciphertext. This article walks you through the methodology, tools, and step-by-step process to decrypt an exclusive HTTP Custom file.

You may need to brute-force the password if it's derived dynamically.

Note: The IV (Initialization Vector) may be static (e.g., all zeros) or prepended to the ciphertext. Check the APK's source for IvParameterSpec.

Instead of trying to decrypt files you don't own:

If you've lost access to a config you legitimately created and need to recover it, the safest path is to contact the app's support with proof of ownership.

Disclaimer: This article is provided for educational and informational purposes only. Decrypting configuration files without the author's permission may violate the Terms of Service of the application or the proxy provider. Always ensure you have the legal right to modify or reverse-engineer a file before proceeding.

If HTTP Custom uses OpenSSL's EVP_BytesToKey (common in older versions), you can use OpenSSL command line directly.

# Attempt to decrypt as if it's OpenSSL salted AES-256-CBC
openssl enc -d -aes-256-cbc -base64 -in exclusive.hc -out decrypted.gz -pass pass:httpcustomkey
Decrypting an exclusive file may violate:

Always seek permission from the file creator before attempting to extract or modify their exclusive configuration.
