A "password of the day" generator for Arris cable modems.

Arris Password of the Day Generator

---

PLEASE READ THIS!

1 - In the past few years, some internet service providers have been changing their modem configurations in ways that prevent this tool from working. If it doesn't work with your modem even though it is in the supported modems list, I'm afraid there's nothing I can do about it.

2 - I am not Spanish or from Latin America. Please don't assume I can speak Spanish or that I have to reply to you in Spanish.

Do you need an Arris modem password? Are you stuck with your Arris modem, in a message that says "in order to access advanced features you must enter the password of the day"? Then you came to the right place!

Description

This is the library that implements the Arris password of the day generator for various Arris cable modems.

Unless you want to help with the code or use it in your own project, you are probably just interested in the online generator. You may also want to check the CLI or the Android app (which is also open source).

For a list of supported modems, troubleshooting options and more information, please visit the help page.

How to use

Install with npm install @borfast/arrispwgen.

The API consists of only two functions: generate(), to generate a single password for a given date, and generate_multi(), to generate multiple passwords for a range of dates.

generate() has one required parameter and one optional parameter:

• date (required): a Date object representing the date for which a password should be generated;
• seed (optional): a string to be used as the seed for the password generator.

It returns a string which is the password for the given date.

generate_multi() has two required parameters and one optional parameter:

• startdate (required): a Date object representing the first date for which a password should be generated;
• enddate (required): a Date object representing the last date for which a password should be generated;
• seed (optional): a string to be used as the seed for the password generator.

It returns an array of objects with two fields: date, a Date object, and password, the password for the corresponding date.

arrispwgen's Issues

Basic Android Port.

A command line version

What the title says :)

I can see this as a node executable that takes a date as an argument. If a second date is provided, it will generate passwords for all the days between the two dates. Perhaps Moment.js can be leveraged to ease parsing the dates.

It can also take a --seed argument to provide a custom seed, otherwise it will use the default.

Any news with the encription key?

There has been a lot of time since someone asked about the encryption key of the router.data file. Any news? I have a file here that needs decoding, but no luck so far...
Thx in advance

Add simple local server

A local server providing a web interface for generating passwords.

Seed in Hex

Hi,
how do i use a seed from snmp that is in hex with this tool?

Detect out-of-order dates in the CLI version

In the CLI version, if the user passes two dates as arguments and the first date is after the second date, arrispwgen exits with an exception thrown by the library.

The CLI version should catch the exception and exit gracefully, telling the user what the problem was.

Won't accept seed length less than 8 characters

Arris's cms will use seeds less than 8 characters. Can you adjust yours to accept less than 8 or can you tell me a way?

Thanks.

Router Arris 1692A

It look like router.data has a new password.
Any idea how can I decrypt this file
the
openssl enc -d -aes-256-cbc -in router.data -out backup.tar -pass pass:Sercomm

return

bad magic number

DES encoded

I will like to know what he's the DES encoded of MPSJKMDHAI ,the arris password of the day tool hes not showing the DES encoded
Thankyu

C# Version

I ported your implementation to C# dunno if you'd like to mention it somewhere (like the README).

Here is the GIST for it: https://gist.github.com/3837628

Find seed from password

do you think that is a hard to reversed a password for find the seed?

Node/npm version, usable in other software

A node/npm version, refactored as a library so that it can be used in other software.

Possible to decrypt the des encoded Seed?

For example the DES encoded of the Seed Test is 8EF7FE3CACF06F43
snmpset enterprises.4115.1.3.4.1.2.3.0 x 8EF7FE3CACF06F43 turns the seed into Test.

Can you find the seed from any DES encoded key?

C++11 port

Unfortunately neither the Javascript nor the C# version is usable from the command line, using Linux.

So I created a C++11 port;
a recent standard compliant compiler/library is needed:
I tested it with clang-3.1/libc++ and g++-4.7/stdlibc++ (and a TM602B modem).

https://github.com/daniel-j-h/TM602X

There's a simple usage example; program arguments and more to come :D
