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.
If a configuration file is leaked, anyone can decrypt the passwords.
Why? Because Huawei uses a embedded in the firmware. The cipher is created by encrypting the plaintext password with a symmetric algorithm (AES-128-CBC or custom Blowfish) using this key. decrypt huawei password cipher

But note: decryption (reversing) is different from cracking. Hashcat attempts brute-force, whereas decryption uses the known key.
Selecting "Skip configuration file" boots the device into an empty, default factory state. Choose the reboot option from the menu. If a configuration file is leaked, anyone can
Restrict access to backup servers (TFTP/SFTP) hosting configuration files, as keeping these files secure prevents attackers from acquiring the cipher strings in the first place.
(where this is legal and appropriate):
: The byte array is processed through a specific loop, performing bitwise XOR operations against the static key bytes, often combined with positional shifts based on the index of the character.
Some older Huawei routers had a hardcoded backdoor user ( root , R& D). This has been patched for almost a decade. Do not rely on this.
