How To Decrypt Http Custom File

with open('config.hc', 'r') as f: content = f.read()

if content.startswith('HC_ENC||'): enc_data = content.split('||')[1]

Decrypting an HTTP Custom file ranges from trivial (Base64 decode) to challenging (AES with hidden keys). Most “encrypted” configs are only obfuscated to deter casual users, not security experts. how to decrypt http custom file

Key takeaways:

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

Rename your .hc file to .ehi (HTTP Injector format) – sometimes HTTP Injector can read basic HTTP Custom files and re-export them in plaintext.

A typical decrypted HTTP Custom file is JSON-based or key-value pair text. For example: With the techniques covered in this 2,500+ word

  "host": "sg1.sshserver.com",
  "port": 443,
  "username": "vpnuser",
  "password": "pass123",
  "payload": "GET / HTTP/1.1[crlf]Host: google.com[crlf][crlf]",
  "sni": "google.com",
  "proxy_type": "SSH",
  "custom_header": "X-Online-Host: discord.com"

When encrypted, this becomes a jumbled string of characters, sometimes prefixed with a static marker like ENV2: or CRYPT:.

Example with Python (RSA):

from cryptography.hazmat.primitives import serialization
from cryptography.hazmat.primitives.asymmetric import rsa
from cryptography.hazmat.primitives import hashes
from cryptography.hazmat.primitives.asymmetric import padding
# Load the private key
private_key = serialization.load_pem_private_key(
    open("private_key.pem", "rb").read(),
    password=None,
)
# Example usage
ciphertext = b'\x34\x54'  # Example ciphertext
plaintext = private_key.decrypt(
    ciphertext,
    padding.OAEP(
        mgf=padding.MGF1(algorithm=hashes.SHA256()),
        algorithm=hashes.SHA256(),
        label=None
    )
)
print(plaintext)
