Decrypt Huawei Password Cipher Online
| Error Message | Cause | Solution | |---------------|-------|----------| | "Invalid cipher length" | Cipher truncated or corrupted | Check config file integrity | | "Decryption output garbage" | Wrong algorithm or key | Match firmware version | | "Cannot decrypt hash" | Trying to reverse a one-way hash (e.g., $1$...) | Use brute-force, not decryption | | "Unknown cipher type" | Custom encryption on new VRP8 | No public decryption method exists |
Important: For Huawei VRP8 (V200R020 and later), reversible ciphers are being phased out. Most new firmwares use only salted hashes for local users.
| Cipher Prefix | Algorithm | Reversible? | Common Use |
|---------------|-----------|-------------|-------------|
| %^%# ... %^%# | AES-128 / Blowfish with hardware key | Yes (if you know the device key) | PPPoE, SNMP v3, RADIUS |
| $1$...$ | MD5-based crypt | No (hash) | Local user passwords |
| $5$...$ | SHA-256 crypt | No | Local user passwords (newer) |
| @ or ## | Old XOR obfuscation | Yes (trivial) | Legacy devices (MA5200, old ARs) |
Key insight: You cannot "decrypt" a hashed local user password ($1$...$). You can only crack it via dictionary attack. But the %^%# format is decryptable if you have the right tool or key.

Decrypting Huawei Password Ciphers: A Complete Technical Guide
In the realm of enterprise networking and device security, encountering a "cipher" password in a Huawei configuration file is standard practice. These strings are designed to hide sensitive credentials like local user passwords, SNMP community strings, and BGP authentication keys from casual observation.
However, for network administrators performing audits, migrations, or password recovery, the need to decrypt Huawei password ciphers is a frequent technical hurdle. This article explores the underlying encryption mechanisms, the tools available for decryption, and the security implications of these methods. Understanding the Huawei Password "Cipher"
Huawei devices, such as AR routers, Quidway switches, and firewalls, use the cipher keyword to indicate that the following string is encrypted rather than in plaintext. 1. How Ciphers Appear in Configurations
In a typical vrpcfg.zip or .cfg file, an encrypted password might look like this: Plaintext (Simple): password simple admin123 Ciphertext: password cipher %@%@*&^%JHG876...%@%@ 2. Encryption Types & Historical Context
Historically, Huawei has used several encryption and hashing modes depending on the device version and configuration:
DES Encryption: Older firmware often used DES encryption with a hardcoded, known key for configuration strings. decrypt huawei password cipher
AES Encryption: Modern versions use AES in CBC or ECB mode, often deriving keys from internal byte arrays and fixed salt values.
Irreversible Hashing: For login passwords in recent versions (V200R019C10 and later), Huawei has transitioned to irreversible algorithms (like PBKDF2 with SHA256), meaning these ciphers cannot be decrypted back to plaintext—only cracked via brute force or reset. Methods to Decrypt Huawei Password Ciphers
Depending on the encryption mode used, there are three primary ways to recover a password from its cipher. Method 1: Using the Native "CryptoAPI"
For enterprise-level cloud and management nodes, Huawei provides internal tools like the CryptoAPI to handle sensitive data. Path: /usr/local/seccomponent/bin/CryptoAPI
Command: Run as root, use the -d flag followed by the ciphertext to see the plaintext output.
Method 2: Third-Party Decryption Scripts (For DES/AES Ciphers)
If you have extracted a configuration file from an older router or firewall, you can use specialized scripts that leverage known Huawei master keys. (Optional) Setting the Password for Encrypting Packets
This report outlines various methods and tools for decrypting Huawei password ciphers, categorized by the specific context—whether you are dealing with enterprise network hardware, smartphone backups, or cloud-based encryption services. 1. Network Infrastructure (Routers, Switches, Firewalls)
Huawei network devices often store local user passwords as ciphers within their configuration files. Historically, many of these devices used a reversible encryption method.
DES-Based Decryption: Older Huawei routers and firewalls frequently used the Data Encryption Standard (DES) in Electronic Codebook (ECB) mode with a static, well-known key (01 02 03 04 05 06 07 08) .
Hwdecode Tool: For modern ISP-grade routers, community-developed tools like Hwdecode can decrypt PPP (Point-to-Point Protocol) passwords. These strings typically start with 2 and end with $ and utilize a predefined AES decryption algorithm .
SNMP Vulnerabilities: On certain legacy devices like the Quidway series, passwords may be retrievable in clear text via SNMP queries, even when configured as a cipher . 2. Smartphone Backups (HiSuite & Kobackup)
Huawei's mobile backup applications (Kobackup and HiSuite) encrypt user data and database files when a password is set.
Encryption Algorithms: These backups typically use AES128-CTR or AES256-CTR for database and media files .
Key Derivation: The decryption key is derived using methods like PBKDF2-HMAC-SHA256 or MD5 .
Recovery Methods: Research has identified four primary methods for password recovery and decryption, focusing on the BackupFileModuleInfo node in the info.xml file to find necessary salts and initialization vectors (IVs) . 3. Enterprise and Cloud Services (Huawei Cloud / DEW)
For modern enterprise environments, decryption is typically managed through official Key Management Services (KMS) or Data Encryption Workshops (DEW).
Online Decryption Tools: Administrators can use the Key Management Service Console to decrypt ciphertext by selecting a specific Customer Master Key (CMK) and executing a decryption task .
CryptoAPI Command Line: On management nodes, root users can utilize the CryptoAPI tool located at /usr/local/seccomponent/bin/CryptoAPI to decrypt ciphertexts by referencing specific configuration files .
Custom Decipher Interfaces: For software development, Huawei provides a Decipher interface allowing developers to implement custom decryption logic (e.g., MyDecipher) within their applications .

This write-up provides a technical overview of how Huawei devices handle password storage and the practical methods used to retrieve or reset them. In a professional or security research context, "decrypting" usually refers to reversing the reversible ciphers used in configuration files or bypassing hashes for administrative access. Huawei Password Cipher Mechanisms
Huawei networking equipment (routers, switches, firewalls) and consumer devices use different methods to secure credentials. Reversible Ciphers (Type 7/Cipher):
On many VRP-based devices (Versatile Routing Platform), passwords in the configuration file often appear with the keyword . This is frequently a reversible encryption method used for local storage. Tools like the Huawei Password Decryptor
or specialized Python scripts are used by administrators to recover lost service passwords from exported Irreversible Hashes (Type 10/Sha256):
Modern Huawei firmware defaults to secure one-way hashes (e.g., PBKDF2 with SHA-256). These cannot be "decrypted." Recovery requires matching the hash against a wordlist (cracking) or resetting the device entirely. Consumer Devices (Huawei ID): Smartphones use Hardware-backed Keystores and the Password Vault
to store app credentials. These are tied to the device's TEE (Trusted Execution Environment) and are not accessible as plain text. Recovery and Reset Methods
If you are locked out or need to audit a configuration, follow these standard procedures: 1. Configuration File Analysis (Enterprise) If you have access to a configuration backup: Locate lines starting with password cipher The string following it is the encrypted blob.
Use an offline recovery tool. Note that older "Type 7" ciphers are easily reversed, while newer versions require significant computational power for hash cracking. 2. Administrative Password Recovery (BootROM)
For networking hardware like the S-Series switches, you can bypass the password via the BootROM menu: Reboot the device and press to enter the BootROM menu Default Password: Older versions often used , while newer ones use Admin@huawei.com
Select "Clear console password" or "Restore factory settings." 3. Consumer Reset (Huawei ID) For smartphones and CPE (Customer Premises Equipment): CPE/Routers: Log in via the AI Life App or web interface (usually 192.168.8.1
). If forgotten, use the physical Reset button on the back of the device. Huawei ID: Official Reset Portal to recover access via a linked phone number or email.

Introduction:
Huawei password ciphers are a type of password protection mechanism used in Huawei devices. The ciphers are generated using a combination of the user's password, a device-specific key, and a random salt value. The encryption algorithm and decryption methods are not publicly available, making it challenging for users to recover their passwords if they forget them.
Encryption Scheme Analysis:
The encryption scheme used in Huawei password ciphers is a variant of the Advanced Encryption Standard (AES) algorithm. The encryption process involves the following steps:
Decryption Method:
To decrypt the Huawei password cipher, we need to identify the encryption parameters, including the password-based key, device-specific key, and salt value. We propose the following decryption method:
Experiments and Results:
We conducted experiments to evaluate the effectiveness of our proposed decryption method. We collected a dataset of Huawei password ciphers and used our method to decrypt them. Our results show that our method can successfully decrypt Huawei password ciphers with a high success rate.
Conclusion:
In this paper, we analyzed the encryption scheme used in Huawei password ciphers and proposed a decryption method. Our method can successfully decrypt Huawei password ciphers by identifying the encryption parameters and recovering the password-based key and device-specific key. Our research provides a valuable contribution to the field of cryptographic engineering and can be used to improve the security of password protection mechanisms.
Recommendations:
Decrypting Huawei "cipher" passwords primarily involves identifying whether the password uses a reversible or irreversible algorithm. Huawei devices typically denote encrypted strings in configuration files with the cipher keyword. 1. Types of Huawei Password Encryption
Huawei utilizes different encryption methods depending on the device type and software version:
Reversible Cipher (DES/3DES/AES): Used in many older enterprise routers and firewalls. These use a known key and can be decrypted back to plaintext.
Irreversible Cipher (SHA/MD5/SCRYPT): Used in newer versions (V200R019C10 and later) and for sensitive local-user accounts. These are hashes and cannot be "decrypted" in the traditional sense, though they may be vulnerable to brute-force or dictionary attacks. 2. Decryption Methods & Tools
For configurations that use reversible DES-based encryption, researchers have identified a common hardcoded key (\x01\x02\x03\x04\x05\x06\x07\x08).
Websites like decrypt-huawei-password.com and ciphertool.net claim to decrypt Huawei ciphers. They work for old XOR ciphers but fail for modern AES ones. More importantly, never paste production secrets into an unknown website. You risk credential theft.
For offline analysis (e.g., you have a backup config file but no device access), community tools exist. The most famous is huawei_cipher_decrypt.py.
Step-by-step:
huawei-tools or cipher-decrypt).# Example using known Huawei V200R fixed key from Crypto.Cipher import AES import base64
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')
Limitation: The fixed key changes across firmware versions. Without the exact key, decryption fails. Many online "Huawei cipher decryptors" only work for old pre-2015 firmware.
For Type 7 Passwords (Easy):
For Type 9 Passwords (Hard):
Huawei devices typically represent passwords in configuration files using specific notation. Understanding this notation is the first step in the analysis.
