For automation and scripting, several command-line utilities exist:

For legitimate users who have lost access to their own equipment, the tools and techniques described here provide essential recovery pathways. However, with this power comes significant responsibility. Always ensure you have proper authorization before attempting any decryption operations. When used ethically and legally, password decryption is not an intrusion but a restoration—returning control of network infrastructure to its rightful administrators.

Huawei password ciphers are a type of proprietary encryption scheme used to protect user passwords in Huawei devices. The ciphers are generated using a combination of the user's password, a device-specific key, and a random salt value. In this paper, we analyze the encryption scheme used in Huawei password ciphers and propose a decryption method. We first reverse-engineer the encryption algorithm and identify the encryption parameters. Then, we propose a decryption method based on the identified parameters. Our experiments demonstrate that the proposed decryption method can successfully decrypt Huawei password ciphers.

For actual security, Huawei recommends using password with irreversible or hash algorithms, or integrating with AAA/RADIUS.

: Use a text editor (Notepad++ or Notepad3) to open hw_ctree.xml . Search for the telecomadmin user entry and locate the Password attribute, which contains the encrypted ciphertext. The typical format appears as:

The $4 encryption scheme represents a significant security enhancement. Unlike $2 , which uses a global static key, $4 employs a —sometimes described as “one device, one secret.” This means that even if you extract a $4 ciphertext from an XML configuration file, decryption without the specific device’s unique key is generally impossible. This mechanism is designed to prevent exactly the kind of offline decryption that tools targeting $2 enable. When used ethically and legally, password decryption is

Modern Huawei devices (and network equipment in general) do not use reversible "encryption" for passwords; they use . This means you cannot simply "decrypt" a password cipher to get the original text. Instead, you must attempt to "crack" the hash by comparing it against a list of potential passwords.

Decrypting Huawei password ciphers represents a fascinating intersection of cryptography, reverse engineering, and practical network administration. From the ubiquitous $2 AES-256-CBC encryption to the highly secure device-unique $4 scheme, Huawei’s evolving security architecture reflects broader industry trends toward stronger, more resistant encryption.
