Certificate conversion from Telnet

[icebreaker]

Hello my friends.

I am able to remote access by Telnet (Port 23) to some DOCSIS 3.0 Modems in my cable network.

I made my search, and i find where the cable modem certificates are, but they output in pain text like the one i attached.

Do you know how to convert this information to certificate files?

Thanks a lot for your precious help.

extract to a folder ,,, input the txt file into the "IN" folder run that .bat file and you certs will be in out folder ... enjoy..

BTW YOU DO REALIZE UPTO 4 PEOPLE NOW HAVE YOUR CERTS , 4 PEOPLE DOWNLOADED IT SO FAR ...

JAVA IS NEEDED!

"Please elaborate on what you exactly mean by this?"
exactly what i said, read it slowly or something,
he posted hes certs Via Text Format ! A
I Posted Text To Cert Converter B

A + B = ? C

Thanks for your answers.

First thing, this is not my personal certs, but someone certs pulled by telnet from a Docsis 3.0 modem in my cable network.

Second, i tryed to do what you have posted, but Buzzcert was unable to convert the certs. I have inputed one text file with all the certs in the folder in, but the software was unable to do the job.

Can you please try yourself and explain me how to do it please?

Thank you all.

It looks like the format of the cert you posted is messed up )) ( )) the parenthesis denoting what cert it is Private etc, are all messsed up.
