# Simplified example salt = data[4:20] # extract salt from header iv = data[20:36] # extract IV ciphertext = data[36:-4] # rest minus checksum
Open Terminal (macOS/Linux) or Command Prompt/PowerShell (Windows) and navigate to the folder containing the script and your backup file: cd /path/to/your/folder Use code with caution. Step 3: Run the Extraction Command mikrotik backup extractor
Once restored, log in and run the /export file=recovered_config command.
Excludes sensitive system-specific data like passwords or encryption keys. Human-readable and editable using any basic text editor. python mikrotik_decoder
RouterOS generates two distinct types of backup files, each serving a different purpose. 1. Binary Backups ( .backup ) Created using the /system backup save command.
Clone or download a reputable MikroTik extraction script from GitHub to a secure directory on your local machine. Step 3: Run the Extraction Human-readable and editable using any basic text editor
key = PBKDF2(password, salt, dkLen=16, count=1000) cipher = AES.new(key, AES.MODE_CBC, iv) decrypted = cipher.decrypt(ciphertext)
There are several scenarios where a configuration extractor is a lifesaver:
# 2. Decrypt if needed if data[2] & 0x01: # encrypted flag if not password: raise ValueError("Encrypted backup needs password") salt = data[4:20] iv = data[20:36] key = PBKDF2(password, salt, dkLen=16, count=1000) cipher = AES.new(key, AES.MODE_CBC, iv) decrypted = cipher.decrypt(data[36:-4]) else: decrypted = data[36:-4]
