Because the exclusive mode uses a static key embedded in the app (sometimes combined with a salt), you need to decompile HTTP Custom.

Using jadx (command line):

jadx httpcustom.apk -d output_dir

Common hardcoded keys found in older versions (example – may vary):

If key derivation uses PBKDF2: Look for PBKDF2WithHmacSHA1 or SHA256. You will need to know the iteration count and salt. how to decrypt http custom file exclusive

If decryption proves too difficult, you can bypass exclusivity by using the app’s own backup feature.

Steps:

This is the easiest and most reliable method for 90% of users. Developers forgot to encrypt the backup file in versions up to v25.
