Select the menu option to or Boot with default configuration .
You paste the ciphertext block (e.g., %@%@...%@%@ ) into the web interface, and the backend script instantly reverses the obfuscation to reveal the password.
Administrators can set a custom master key using the master-key command. This significantly increases security, as the cipher cannot be decrypted without knowing this unique custom key. Methods to Decrypt Huawei Password Ciphers decrypt huawei password cipher
For advanced users who need to modify encrypted passwords without decrypting them first:
In conclusion, the phrase "decrypt Huawei password cipher" is a misnomer that conflates hashing with encryption. Huawei protects passwords through irreversible hashing algorithms like MD5 and SHA-2. While these cannot be "decrypted" in the traditional sense, weak passwords hashed with older algorithms can be cracked using computational methods. Understanding this distinction is essential for network engineers, not only for securing devices against unauthorized access but also for managing legitimate recovery procedures. Ultimately, the security of a Huawei device relies not on the secrecy of the algorithm, but on the strength of the password and the integrity of the configuration management.

On older firmware, if you have console access but your password is shown in cipher, you can set a new one:
If you encounter a reversible cipher in a configuration file, you can often revert it to plaintext using specific tools or official procedures. 1. Using Official Management Tools
Input the default BootROM password (commonly Admin@huawei.com , huawei , or Huawei@123 depending on the hardware model). This significantly increases security, as the cipher cannot
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
: Your plaintext password and device configuration are sent to a third party. Only use offline tools for production gear.
With modern Huawei ciphers (indicated by the $1a$ prefix), the device does not store the password. It stores the result of a mathematical formula.
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.
When you export a Huawei device configuration using commands like display current-configuration , you often see lines such as:
