Reversing / Decompiling of a small Linux Binary (c++ elf 11kb)

there is a small linux tool where i need the sourcecode and something like a "password generator" for it.

download it from the following url and take a look...

[url removed, login to view]

this small program take a little information from a linux terminal and build/generate a password from it and store it after encrypted format in passwd/shadow

i need the sourcecode of this small program and a password generator!

(to get the password in plain before it get encrypted. so i can use it to login into the terminal [password generator [with source])

the password generator i need in SOME HOURS (and sourcecode of the whole tool max some days later)

tell me if im wrong but i think it reads only one value from the system (a hexcode like 00112233AB) and generate a password from it (with some other fixed other stuff/values from this program)

for a reverse this is a easy job!

im willing to pay more as this project should cost in my opinion because i need the passgen very fast.

some facts about this project:

1. as told before. the password generator must be finish in a few hours maximum. so if you do not provide it in the same day, i will search for another freelancer and you will not get paid.

2. i will not pay any milestone to any possible ripper or time waster without a proof of work from the passgenerator side. but i do not want any code or program before i payd! (1 part for passgen 1 part for source).

as proof of work you have to generate two passwords for me (wanna try one in VM and one on real hardware). i will provide the sample data what u will need (hopefully just the hex) to generate a password for this terminals. how many chars have the provided sample hexcode? write it in your bet to verify that you read what i wrote.

i will try the passwords and if i can login with this passwords i pay the first milestone to get the password generator from you. and the rest when you can provide me the source (or a source, the program is pretty simple when you understood it so you can write a small one by yourself. its not important for me to see the original code just a program that do the same)

3. the two IDs:



IF this is as i think all information you need and if you want to show me how good and fast you are. i dont have a problem when u send me the passwords for this IDs before i choosed somebody.


offtopic final words:

i know that here are SOME honestly and good guys . but they are hard to find. a good "man" will get more jobs after this randomly (as needed)

the following keywords should not be a foreign language for you :-)

reversing, linux, kernel, programming, squashfs, drivers, c/c++, hacking, source code analysis, buffer overflow.

dont be afraid to post some words more in the bet!


cheers and happy bidding
