Always remember that modifying a device's configuration can have unintended consequences, potentially rendering it inoperable. The sensitive information you uncover (like passwords) should be treated with the utmost security. Decrypt and modify configurations only for devices you own or have explicit permission to manage.
The tool echoed back its usage instructions: Usage: hwcfgdecrypt <input_file> <output_file> <key>
Huawei configurations historically used different encryption types, primarily categorized by identifiers in the configuration file:
Verify the provided on the download page against your downloaded file to ensure integrity. Open-Source/Third-Party Tools
If you have lost the password for a Huawei device: Always remember that modifying a device's configuration can
) can extract local user credentials from configuration files. : Requires Python and the PyCryptodome : It uses a known DES key ( \x01\x02\x03\x04\x05\x06\x07\x08 ) to decrypt the strings found in the exported config files. Huawei Backup Decryptor (kobackupdec)
Available within the ManageOne Operation Portal . It allows VDC administrators to encrypt or decrypt sensitive configuration strings (like database passwords) directly in the browser.
A security controller that automates security policy orchestration and handles encryption for data centers and campus networks.
This article explores the native tools Huawei provides for configuration encryption/decryption, how to install them, and best practices for handling sensitive configuration data. The tool echoed back its usage instructions: Usage:
This was the first hurdle:
: Log in as a VDC Administrator, locate the tool download button on the left sidebar, and select the guide matching your hardware (e.g., SanSec or TASS). CLI-Based Encryption
A comprehensive platform that delivers encrypted device configurations using protocols like NETCONF (supporting AES-128/256-CTR).
: Modern Huawei VRP versions employ robust algorithms like AES-256-GCM, PBKDF2, and RSA for configuration file encryption and password hashing. cipher 加密字符串 )
If you have an offline configuration file containing a reversible cipher string (e.g., cipher 加密字符串 ), paste the ciphertext string directly into your verified decryption utility. If the string uses an older algorithm, the tool will instantly output the plaintext password. Encrypting New Configuration Files for Deployment When preparing configurations for remote deployment: Open your configuration tool or network management console. Input your plaintext deployment commands.
./huawei
Requires no installation. It is an online utility within the VDC administrator/operator console.
