What type of encryption has been used to Zyxel VMG8924-B10A config file?

"owned by the operator...I cannot upload an alternative software.I'm only leasing the router.."

It look like the one before the cable modem Docsis 3,i had a cisco locked by operator,config is checked like the cable modem almost 100x/day,even if you can upload a new config,seen and reported to them and then...
maybe it's not your case but be safe.

I have managed to make a dump flash (another router of the same operator) with the manual:

Unfortunately, I don't know which tool I should use to change it into .bin.

If you could have a look, please check if the root's password is there.

If I am changing that file into .bin, do I have to delete the selected data?

Dump comes from 8 MB flash and it's here:

From what i have seen it seems a textual representation of binary data, i don't think you will find a tool to convert it to bin but it should be very easy to write a conversion script in python, you can do it by yourself. Make a backup, remove the first column (the one with "address: ") and the last one (data display, the one with the dots etc), you want a text file where every line is a 16 byte text representation

10 00 02 7b 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

etc.

then write a python script which reads the resulting text file and for every line of text converts the 16 byte text representation to 16 real bytes and then writes them to a new binary file incrementally. At the end you should have your bin file (check it with an hexeditor, you should see the same bytes as the original text). Then you could try to analyze it with binwalk, Ida etc
