def decrypt_huawei(cipher_text): # Remove delimiters enc = cipher_text.strip('%^%#') # Decode from base64 enc_bytes = base64.b64decode(enc) # Fixed key for V200R009-V200R019 (example) key = b'\x00\x01\x02...' # Redacted for security cipher = AES.new(key, AES.MODE_CBC, iv=b'\x00'*16) return cipher.decrypt(enc_bytes).decode().rstrip('\x00')

If you are locked out of your own device and cannot decrypt, your last resort is a factory reset (using the reset button or bootrom menu ) – which wipes the configuration.

Avoid simple patterns or 4-digit PINs.

When network administrators lose access credentials to Huawei routers, switches, or optical network terminals (ONTs), the encrypted strings embedded in configuration files often appear as indecipherable gibberish—strings like $2!L/n=Ap6>T#}t[*t($rK;7v99l(/i8GCG7:TJ<6XHhik.#Nr>KHF $V:ONv8y_~<7z0Us)_kKqM{\C`—that offer no clue about the actual password.

Another high-tier forensic tool designed for memory dumping and password bypassing. D. EDL Mode (Emergency Download Mode)

: The ciphertext is typically an ASCII-encoded string that can be converted to binary and decrypted using the fixed key \x01\x02\x03\x04\x05\x06\x07\x08 in ECB mode. : Open-source scripts like huaweiDecrypt.py automate this extraction and decryption process. AES-based PPP Passwords decrypt huawei password cipher

Older VRP daemons may default to weaker cipher styles. Keep device firmware updated to ensure the system utilizes updated cryptographic libraries and defaults to non-reversible algorithms.

: Launch Huawei Configuration Encryption Tool, select the $2 decryption option, paste the complete encrypted string, and execute decryption.

: Upgraded to multi-layer encryption chains that first verify configuration integrity using HMAC-SHA256, then encrypt sensitive fields with AES-256-GCM using random keys generated by the device’s built-in TRNG (True Random Number Generator). The ciphertext, IV, and AAD are stored at specific offsets within the configuration file. ( save secure-configuration ) to store encrypted backups

Using the online decryption tool, they successfully deciphered the credentials.

Deprecated across all modern enterprise devices. 2. Cipher Type 10 (Legacy Reversible Encryption)
