I am myself a C# developer, and I am interested in interfacing with my phone through USB, but without using ADB command lines.
Is there any project going on what's goal is to create a C# interface for Android phones?
Mostly data management, like file browsing, and such things, and of course sync, the reboot options, device listing and resolving, application management, and so on.
Hi,
If you want, you can use the DroidExplorer source code. Take a look in the namespace DroidExplorer.Core.Adb
That's what I did, but it "just" binds the adb executable with all the commands, while I am looking for a pure C# solution, without involving adb.exe!

Are you sure ?
Take a look in the class DroidExplorer.Core.Adb.AdbHelper. This class only use pure sockets
Code:
public Socket Open ( IPAddress address, IDevice device, int port ) {
Socket s = new Socket ( AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp );
try {
s.Connect ( address, port );
s.Blocking = true;
s.NoDelay = false;
SetDevice ( s, device );
byte[] req = CreateAdbForwardRequest ( null, port );
if ( !Write ( s, req ) ) {
throw new IOException ( "failed submitting request to ADB" );
}
AdbResponse resp = ReadAdbResponse ( s, false );
if ( !resp.Okay ) {
throw new IOException ( "connection request rejected" );
}
s.Blocking = true;
} catch ( IOException ) {
s.Close ( );
throw;
}
return s;
}
Yes, uses pure sockets to connect to Adb.
Take a look:
Code:
public int GetAdbVersion ( IPEndPoint address ) {
byte[] request = FormAdbRequest ( "host:version" );
byte[] reply;
Socket adbChan = new Socket ( AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp );
try {
adbChan.Connect ( address );
adbChan.Blocking = true;
if ( !Write ( adbChan, request ) )
throw new IOException ( "failed asking for adb version" );
AdbResponse resp = ReadAdbResponse ( adbChan, false /* readDiagString */);
if ( !resp.IOSuccess || !resp.Okay ) {
this.LogError ( "Got timeout or unhappy response from ADB fb req: " + resp.Message );
adbChan.Close ( );
return -1;
}
reply = new byte[4];
if ( !Read ( adbChan, reply ) ) {
this.LogError ( "error in getting data length" );
adbChan.Close ( );
return -1;
}
String lenHex = Encoding.Default.GetString ( reply );
int len = int.Parse ( lenHex, System.Globalization.NumberStyles.HexNumber );
// the protocol version.
reply = new byte[len];
if ( !Read ( adbChan, reply ) ) {
this.LogError ( "did not get the version info" );
adbChan.Close ( );
return -1;
}
String sReply = Encoding.Default.GetString ( reply );
return int.Parse ( sReply, System.Globalization.NumberStyles.HexNumber );
} catch ( Exception ex ) {
Console.WriteLine ( ex );
throw;
}
}
The adbChan socket is used to connect to ADB over TCP. Also there are listeners for ADB responses, and a forwarder to send ADB commands.
I will just leave this here. :good:

Just a quick question: My phone was swapped by a repair shop and the other person who got my phone didn't realize this at first. She did a factory reset, and probably installed Whatsapp with her SIM card before I got my phone back. I'm so angry right now...
I guess my key file is gone - either deleted by the factory reset or overwritten with her Whatsapp's key file. I have several backups of the Whatsapp directory and still the same Google account, IMEI and phone number. Can I restore my messages or are any attempts futile?
(I see that the code asks for a key file, so if I cannot get it/extract it somewhere, there is probably no chance anymore?)
hi, realy great tool
with that i could open the msgstore.db and see my chats
but is it possible to convert this file into a .db.crypt12 file or something like that, so i can open it with whatsapp an have my chats back?
or are there other ways, i can use this msgstore.db + wa.db to recover the chats?
Hi!
I have a crypt12 database but no key...is there anyone out there able to decrypt it?
How much will it cost to me to do this? Can anyone do it for me?
Is the code written here above working in decrypting a crypt12 database?
I don't want to root or install any spyware, just trying to decrypt the file.
anyone interested in trying?
Please write dawn here if you're interested and we'll get in contact...

There is a program out there which claims to obtain the key file without root. If it's still working today, I don't know. Here: https://forum.xda-developers.com/showthread.php?t=2770982
If you want the key file, it's better to root your phone and get it. It's not that hard. You can even unroot your phone after catching the key.
And no, someone can't just decrypt the database, because the key is there for a reason, and this reason is security.
Excellent! Just used this to fix a Whatapp DB.
---------- Post added at 10:57 AM ---------- Previous post was at 10:50 AM ----------
This is great thanks! How do I encrypt the database again with crypt12?
I have both, the DB and the key.

It give you de key file whithout root. It worked for me. But it is a little tricky. and you end up with this modded whatsapp.

You need to re-download WhatsApp in another phone and use your old number. (Yes, you'll need to recover your phone number before recovering your chats). Once you have WhatsApp installed you can take out the Key file from /data/data/com.whatsapp/files
To do that stuff i recommend to use a old phone that can be easily rooted or one that has already rooted.
Good luck :good:
Hello,
Does anyone know if by any chance KEY file gets deleted on old phone when whatsapp is activated on a new phone and old phone whatsapp gets locked asking for conf code by SMS?
I rooted android 4.x.x
I then searched using ez file manager in root and in data/data /com.whatsapp but i do not see a KEY file.
download WhatsApp Plus8.30 it will work for you

I have whatsapp db.crypt12 file. I am novice in Mobile. Can anybody make that file readable professionally for me? I am ready to pay for this.
HI,
I have extracted the key by the procedure of "WhatsApp Key/DB Extractor 4.7 Enhanced 1.0" (https://forum.xda-developers.com/showthread.php?t=2770982&page=55), but eventually your JAVA code failed with message:
Key file mismatch or crypt12 file is corrupt.
Why is that?
Somewhere (guess at Elcomsoft Explorer) I have read, that the key can only decrypt backups taken from a previous time. This should true in my case, isnt?
1) Is the key somehow related to the phone device itself? (I have used a spare phone for this analysis, so not the original WA was regularly running on.)
Since end of August (when an Upgrade of WA has destroyed my chat history database) I have tried several attempts to restore it by downgrading WA to 2.20.64 and 2.20.89, so the key I have now is not the original of what the crypted backup was created with.
Moreover, due to a database schema error my chat history can only be loaded with WA version previous to 2.20.89 (this is why: https://medium.com/@leonardocezaryc...hatsapp-windows-phone-to-android-6b225918af55)
My experiments now led to the situation, that I not any more can register any pre-2.20.89 version by the SMS verification process, even though I dated my phone back to mid of August.
Thus I currently have no working installation with all my chat history where I could extract a crypto key from.
2) Any ideas how i can bypass Whatsapp to complain about its expired versions and register by SMS again?
3) Is it a hard-coded deadline in the binaries of the app?
4) Does the crypt key change between installations and become incompatible? I wonder, how to restore any old backup then...
Thanks!

Yes - upon inactivation WA 2.20.89+ destroys the "key" file and instead creates a "backup_token" file.
It is recoverable by activating it via SMS code.

What kind of problem can't you solve so far?
There is a commercial solution called "Elcomsoft eXplorer for WhatsApp ".
I also would like and am about to try it out, if you are interested, we can share the costs of it.
After years of successfully using this to access MY chat data, this week it stopped working :-(
WhatsApp on my phone looks to have updated to v2.21.8.17 and is now generating local backups with a .crypt14 extension instead of .crypt12.
Unsurprisingly, this chokes on this with the error Key file mismatch or crypt12 file is corrupt.
However, armed with hexdump and a bit cunning, I've worked out how to tweak the python so that it successfully decodes .crypt14 files.
in a .crypt14 file ... [.py hacks in decrypt12 function shown below in square brackets]
... t2 is at offset 14 [so change to crypt12.seek(14) t2 = crypt12.read(32)]
... iv is at offset 66 [change to crypt12.seek(66) iv = crypt12.read(16)]
... encrypted content starts at offset 99, (I haven't yet worked out the correct amount of footer to remove, but removing 0 seems to result in a successful decryption so far) [change to crypt12.seek(99) primer(tf, crypt12, 0)]
I've also noticed that the 16 bytes at offset 62 to 77 in the key file also appear in the .cryptX file, just like the t bytes at offset 30 to 61 do.
In a .crypt12 file they are at offset 35 to 50.
In a .crypt14 file they are at offset 48 to 63.
In my code I've called these x1 and x2 and do the same equality check as happens for t1 and t2.
In addition, in the .crypt14 file, bytes at 86 to 94 look to contain the WA version number, so in my case 2.21.8.17 - presumably the version that wrote the .crypt14 file. I suspect that when the version number rolls over to more digits (e.g. 2.21.10.10) then the offset to the start of the encrypted content (currently 99 in my backup files) might well change?

It's not working for me for some reason. I don't know what I am missing here. Can you provide the modified code itself?
