huawei-dg8045-hg630-hg633-Config-file-decryption&encryption-and-password-decode

Usage :dg8045.py decrypt inputfile outputfile

It cannot encrypt the config file because the signatures are missing

It decrypts the encrypted passwords too

the Userpassword is stored as an encrypted string that when decrypted outputs a SHA-1 hash

made from the password and the salt from the config file

To create it

import hashlib

t = hashlib.pbkdf2_hmac('sha1', b'thepassword', b'salt', 1000, 16).hex()

print(t)

hg630/hg633 decryption&encryption

decryption :

Usage :hg633.py decrypt inputfile outputfile

encryption :

Usage :hg633.py encrypt inputfile outputfile

To decode the encrypted passwords

Usage :hg633decode.py decrypt inputfile outputfile

note that you can only encrypt the config file generated by hg633.py not hg633decode.py because of the decoded passwords

in some cases/routers it decodes all the passwords expect the admin cause the needed IV is different or unknown for that ISP

To manually decrypt passwords

Usage : sdecode.py encryptedstring
