Huawei VRP introduces a concept. The master key is used to encrypt all other cipher text passwords within the configuration file. If a network administrator changes the default master key, the underlying cipher texts change format, drastically increasing the security baseline of the configuration backup. Downloading Huawei Configuration Tools
: Network administrators frequently use this feature when a configuration backup exists but the current admin password is unknown—a common scenario in maintained infrastructure.
Huawei's configuration encryption and decryption tools are indispensable for advanced network management and troubleshooting. Whether you need to recover a lost administrator password, migrate configurations between devices, or simply analyze your network's security posture, these utilities provide the necessary capabilities. : Huawei VRP introduces a concept
: You extracted an encrypted password field ( $2 format) from a configuration file and need the plaintext value.
Official Huawei tools generally do not require standard "installation" but rather deployment within their respective environments. Cloud Tools : Access is granted through the Huawei Cloud Enterprise Support portals using valid administrator credentials support.huawei.cn CLI Utilities : Tools like
To encrypt a configuration file, Ahmed used the huawei_cfg_encrypt tool. He ran the command, specifying the input configuration file, the encryption password, and the output encrypted file. The tool encrypted the configuration file using a symmetric encryption algorithm, ensuring that only authorized personnel could access the file. : You extracted an encrypted password field (
The tool works offline, requiring no active Telnet/SSH session. It achieves this through deep reverse engineering of Huawei's CLI configuration mechanism, internal encryption algorithms, and firmware structures. For each device model, it loads the corresponding algorithm module ( ar100_decrypt , s5735_decrypt , usg6000v_decrypt , etc.).
Unlike the open-source ONT tool, huawei.exe is a community-developed utility specifically targeting :
Run the application as an administrator to prevent file permission conflicts when importing or exporting configurations. How to Use the Encryption and Decryption Tool S-series switches) are you working with?
Then, he used the specific command to decrypt it on the device (provided he had the super admin password, which he did). <Core-Router> configuration decrypt configuration.cipher configuration.txt
: A Python script designed to extract and decrypt local users and passwords from Huawei router/firewall configuration files using DES encryption Installation and Setup
: Accessible via the Key Management Service console. You can enter plaintext to generate ciphertext or vice versa for small-size sensitive data.
