Use a brute-force XOR single-byte key search (0-255) and check if output contains { or "host" . Method 3: AES Decryption – When Stronger Methods Are Used Paid configs sometimes use AES-128-CBC. You’ll notice the file starts with a fixed header like Salted__ (for OpenSSL) or AES: .
import base64, re, json def try_base64(data): try: return base64.b64decode(data).decode() except: return None how to decrypt http custom file
with open("input.hc", "rb") as f: raw = f.read() plain = try_base64(raw) if not plain: plain = try_xor_bruteforce(raw) Use a brute-force XOR single-byte key search (0-255)
The file is extremely small (under 100 bytes) Solution: It might be a link to a remote config. Look for https://pastebin.com/raw/... in the plaintext. how to decrypt http custom file
