: Developers often use Python-based scripts to reverse-engineer these files. You can find repositories such as HCTools/hcdecryptor or DjKadex/hcdecryptor-1 on GitHub .
He realized earlier that standard Base64 failed. He tried a simple rotation cipher (ROT13), a common trick in amateur obfuscation, followed by Base64.
files aren't just random data; they are encrypted configuration blobs that the app uses to establish secure SSH or VPN tunnels. To "decrypt" it, Alex found a utility called hcdecryptor on GitHub.
Ensure you are using the correct SSH/SSL/Payload mode in the app. Conclusion

It’s not true encryption — it’s obfuscation. XOR with a static key and Base64 encoding.
: Place your .hc file in the script folder and run: python3 decrypt.py yourfile.hc
# Split into parts parts = decrypted.decode().split("|") return "file_id": parts[0], "timestamp": parts[1], "user_key": parts[2]
Lena opens the older app in a disassembler (like dnSpy for .NET or Jadx for Android) and finds a function named buildDownloadLink . She sees: He tried a simple rotation cipher (ROT13), a
This is almost always caused by using an outdated version of the decryption tool. The HTTP Custom app is periodically updated, and the developers may change the encryption key. The tool you are using might only have the older keys in its keylist. The HCTools team and other developers actively update them when new keys are introduced.
She used it to decrypt an RSA private key she found embedded in the HTTP custom app’s memory dump (she had reverse-engineered the APK earlier). The passphrase unlocked the key. Then she decrypted the session key:
"If I click the link," he reasoned, "the app will decrypt it to connect to the server. I just need to catch the handshake."
: Using third-party decryption scripts can be risky; ensure you audit the code or source them from reputable developers like those on Ethical Use Ensure you are using the correct SSH/SSL/Payload mode
Decrypting files may violate the creator's terms.
Note: This post assumes you legitimately own or have explicit permission to access the file and link. Do not attempt to decrypt links or files you don’t have authorization for.
If your goal is simply to use the file rather than see its contents, you can import it directly into the HTTP Custom app : Open . Tap the Plus (+) icon at the bottom right. Select Open Config . Navigate to your downloads and select the .hc file. How to import and export http custom files
