If you have physical or serial console access to the Huawei hardware, you can reset the password safely without losing your existing configuration data.
The plaintext password is combined with a unique, randomly generated system salt.
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 decrypt huawei password cipher

: Factory reset erases all existing configurations, including Wi-Fi names, custom settings, and user data. If you have physical or serial console access
Network administrators managing Huawei enterprise devices—such as Quidway switches, AR routers, and USG firewalls—frequently encounter password ciphers in configuration files. Whether you are performing a security audit, recovering a lost credential, or migrating a legacy configuration to a new platform, understanding how Huawei encrypts and decrypts these strings is a critical technical skill.
Show you how to change the encryption type to for higher security. Whether you are performing a security audit, recovering
The software computes hashes for millions of candidate passwords per second from a wordlist (like rockyou.txt ) until a matching hash is found.
Several security researchers have reverse-engineered the Huawei cipher method. You can use online tools to decrypt the string directly.
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.
