To address the weaknesses of the legacy format, newer Huawei VRP versions (VRP v8 and updated VRP v5 branches) introduced the $1c$ prefix.
# Save the hash to huawei.hash john --format=md5crypt huawei.hash --wordlist=rockyou.txt decrypt huawei password cipher
from Crypto.Cipher import AES import hashlib # High-level logic representation of legacy/default VRP decryption def decrypt_huawei_cipher(cipher_text, master_key_default): # 1. Parse the cipher text to extract IV and encrypted payload iv = cipher_text[:16] encrypted_data = cipher_text[16:] # 2. Derive the actual decryption key using Huawei's specific KDF derived_key = hashlib.sha256(master_key_default).digest() # 3. Decrypt using AES-CBC mode cipher = AES.new(derived_key, AES.MODE_CBC, iv) plain_text = cipher.decrypt(encrypted_data) return plain_text Use code with caution.
Reboot the device. It will boot into a factory-default state or bypass the login prompt. Log in with the default administrator credentials, restore the network configuration from a secure backup, and immediately configure a new, strong password. 5. Best Practices for Hardening Huawei Configurations Derive the actual decryption key using Huawei's specific
If your configuration string looks like cipher $1a$XyZ... , you can utilize Python scripts available on security repositories (such as GitHub) that emulate the VRP decryption routine.
Paste the ciphertext block into an offline Python decryption script or a trusted offline security tool to instantly reveal the plaintext password. Method 2: The Configuration Replacement Technique It will boot into a factory-default state or
In the context of network devices (routers and firewalls), Huawei utilizes several "cipher" formats for storing passwords in configuration files. Depending on the device type and age, these can often be reversed: Common Huawei Cipher Types & Decryption Methods Simple DES-based Ciphers
