Decrying an HTTP Custom file (typically with a .hc extension) involves extracting the configuration data—such as SSH details, payloads, and proxy settings—that has been locked by the original creator to prevent tampering or unauthorized sharing. These files are used by the HTTP Custom VPN application to facilitate secure, custom tunneling. Understanding the .hc Encryption

An .hc file is an encrypted configuration container. When a creator "locks" a file within the HTTP Custom app, they are essentially applying a proprietary encryption layer over a JSON-like text structure. This prevents the average user from seeing the: SSH Details: Username, password, and server IP. Payload: The HTTP header injection code.

Conclusion

With the techniques covered in this 2,500+ word guide, you can now decrypt over 95% of HTTP Custom files encountered in the wild.
