[HELP] SteamPWD

MAJOR · **Joined:** 06 Mar 2009 04:34 **Posts:** 4

I want to be able to open the file, and not have to choose the .blob file myself. Is there any way to open SteamPWD and have it choose automatically?

can i just add this \\ClientRegistry.blob to Software\\Valve\\Steam\\ and have it work? without having to choose the file?

[code]"Software\\Valve\\Steam\\ClientRegistry.blob", "SteamPath",
steampath, sizeof(steampath));
if(steampath[0]) {
for(p = steampath; *p; p++) {
if(*p == '/') *p = '\\';
}
}
fname = get_file(steampath);
} else
#endif

if you want it to work in all computers, then no. well it should work with the path if it is installed into default path, but for example my steam is in C:/Games/Steam

to automatically load clientregistry.blob it's enough that you substituite "fname = get_file(steampath);" with the following line:

fname = strcat(steampath, "\\ClientRegistry.blob");

Luigi do i just replace the code that you've fixed? and i've been having errors compiling is there any compiler you prefer? with all the files i need? Thanks a bunch. Haven't seen anyone so devoted in helping other people!

edit: Luigi if you don't mind just compiling it for me then thanks, but if you want me to learn then thanks too : )

practically after the modification that part of the code must look like:

Code:

...
            if(steampath[0]) {
                for(p = steampath; *p; p++) {
                    if(*p == '/') *p = '\\';
                }
            }
            //fname = get_file(steampath);
            fname = strcat(steampath, "\\ClientRegistry.blob");
        } else
#endif

I use Mingw as compiler:
http://www.mingw.org/wiki/HOWTO_Install ... iler_Suite
or the the most recent build http://www.tdragon.net/recentgcc/

about compiling is better if you do it by yourself because is bad to be dependent by someone else, in any field.

Thanks for the quick response, i don't know how to use mingc ...i'll try

edit: looks about right?

Code:

  fputs("\n"
        "Steam password decoder "VER"\n"
        "by Luigi Auriemma\n"
        "e-mail: aluigi@autistici.org\n"
        "web:    aluigi.org\n"
        "\n", stderr);

    fprintf(stderr, "\n"
        "Usage: %s [ClientRegistry.blob/password] [key]\n"
        "\n", argv[0]);

    if(argc < 2) {
#ifdef WIN32
        if(GetWindowLong(GetForegroundWindow(), GWL_WNDPROC)) {
            regkey(
                HKEY_CURRENT_USER,
                "Software\\Valve\\Steam\\ClientRegistry.blob", "SteamPath",
                steampath, sizeof(steampath));
            if(steampath[0]) {
                for(p = steampath; *p; p++) {
                    if(*p == '/') *p = '\\';
                }
            }
            //fname = get_file(steampath);
            fname = strcat(steampath, "\\ClientRegistry.blob");
        } else
#endif

I pressed g++ and got this

yes the modification is correct.

the exact compiling command is:

gcc -s -O2 -o steampwd steampwd.c c:\mingw\lib\libcrypto.a -lgdi32 -lcomdlg32

libcrypto.a is available here: http://downloads.sourceforge.net/gnuwin ... -1-lib.zip (put all the content of that zip in your c:\mingw folder)

THANKS ALOT. WOW GREAT HELP!

edit:
Hey Luigi how do you make it save to a .txt as a log file after it finds the password in the current directory?

I was interested in this change, and decided to modify it. It compiles fine, but the program claims it can't find the blob file. The message reported is:

Error: please specify the location of the blob file or directly the encrypted password.

I have checked on both Vista 64 bit and XP 32 bit, and am getting the same error in both places with this change. The registry entry for the steampath also exists on both machines, and the value of "SteamPath" is correct (comparing to where steam was installed).

Also, your compiled version (where you have to manually choose the blob file) works just fine on both machines. Is there a problem with the modification line? Maybe it's not querying the registry correctly? Reason I ask if there is a problem is because the change failed on 2 different machines, but it may be an error on my part too.

Here is a pastebin of the modified code: http://pastebin.com/f48359e29

Compiled with mingw gcc 3.4.5 using: gcc -s -O2 -o steampwd steampwd.c c:\mingw\lib\libcrypto.a -lgdi32 -lcomdlg32

that line is howed only if the tool is launched from command-line without arguments.

obviously it's not your case (otherwise you had the same effect also with my version) so the guilty is probably your version of gcc which doesn't have WIN32 defined (watch line 86).
are you using gcc from mingw or from cygwin?
if you use the cygwin one it's normal because it doesn't set that define WIN32

Ah stupid me, I was running it from the command line without arguments. Double clicking on the compiled .exe within Windows allowed it to work just fine. What change would you do to make it purely command line only, so it automatically:

- queries the registry for the steam path
- changes the "/" to "\\"
- echoes the password, and ends the program without waiting for the RETURN key

..?

Thanks!

first the same modification explained above (for forcing the loading of the default blob file in steampath), then substituiting the first "GetWindowLong(GetForegroundWindow(), GWL_WNDPROC)" with 1 and the second one with 0.
if you need to convert / in \ you can use something like the following just after the assigning of fname:

Code:

fname = strcat(...blah...):
for(p = fname; *p; p++) {
    if(*p == '/') *p = '\\';
}

Thanks! Works great :)
