Okay, thanks for your reply, I will try your method first, and then tell you the result of my attempt

from crylogger.

Thanks! Sorry, but you need to create the emulator by using the method explained in the README. We modified the Java library to print the log. If you use a different emulator, you use the standard Java library and therefore the file application.cryptolog is not created.

Little personal suggestion is that u can add this requirement which need to create the emulator as README doing to the supplementary document, so that others wont meet the same problem as above ~~ Great thanks a lot ~~

from crylogger.

Hi, if you build the emulator as explained in the instructions (the emulator you run from the directory emulator-emu that is created with the script scripts/setup/setup_emu.py) you will run your applications with our modified Java library. You can find the modifications to the Java library in scripts/deltas/libcore/ojluni/src/main/java. Thanks

Many thanks for your reply and guide

from crylogger.

Hi, thank you. The compilation process can be a little complicated because there are several dependencies. In your case, it looks like the error is "error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory". Try to install this library in Ubuntu. Thanks!

Hi, many thanks for your patient reply and guidance!
The compilation is successful! And I tested the given application mentioned in the file "readme" successfully. But when I tested other apps, a line of instruction, "install | failed", appeared. Could you please give me some guidance? Many thanks!

from crylogger.

Sorry for misunderstanding. The script run.py assumes that you have the apk of the app to install. If the app is already installed on the emulator, e.g., by using the marketplace, you need to modify the script to skip the installation step and find a way to provide the name and the package to the script. So you need to modify manually the Python script as it does not provide the functionality that you're asking.

Regarding the apps, I tested several apps. Please try some of the Google Play Store. If the installation is successful and the app works correctly, you should be able to get the log of the cryptographic APIs. If you don't find the log it means that the app has not been executed for enough time. In one of your previous screenshots, an app was running successfully, please try to extract the log from that one. The log should be in the directory /data/data/<app-package>/cache.

I hope this helps.

Many thanks for your patient reply and guidance!
I have already solved all the problems mentioned above.
Maybe someone added a necessary snippet code to the file "build.gradle" in his app so that the app can be installed in the given X86 emulator, but others did not do like this.

from crylogger.

Learn from your previous Issue, I just run the test application that is included in the folder app-test, but it still was error.

from crylogger.

Hi, can you please check if there are other files in the directory /data/data/com.example.aes/? There should be a file called aes.log in one of the subdirectories. Can you confirm that the file aes.log is there? This is to make sure that the application was executed successfully. Can you report the content of this file?

from crylogger.

Yeah, there is file aes.log in the directory /data/data/com.example.aes/, and the content is:
[decrypted: The quick brown fox jumps over the lazy dog]

from crylogger.

Ok, great. Can you please go inside the directory android-emu/libcore and run the command git status?

from crylogger.

I created the emulator manually and did not use the method in the README, so there is no android-emu directory in my root directory. I didn't execute these commands in the picture below.

Hi, I built the emulator as explained in the structions, but now I have a problem. When I entered the script "emulator" or "emulator -writable-system", a line of instruction, “emulator: ERROR: No initial system image for this configuration”, will appear.
Then I searched it in google, but no satisfying results occured. Could you please give me some guidance? Many thanks!

Hi, I think there is some sort of issue with the compilation process.
Please go inside the directory android-emu and then do the following:

source ./build/envsetup.sh
lunch sdk_phone_x86-userdebug
make

This re-compiles the emulator. Is the compilation successful?

Thanks

Hi, When I followed your instructions, a new problem occured. Both "./build/envsetup.sh" and "lunch sdk_phone_x86-userdebug" are successful, but when I entered "make", a line of instruction, "failed to build some targets ", appeared.
Maybe you have encountered this kind of problem before, Could you please give me some guidance? Many thanks!

Hi, some apps I downloaded successfully, but it can not pin and uninstall. Could you give me some guidance? Many thanks!

from crylogger.

Yes you can run apps from the Google Play Store. However, some apps cannot be run on an emulator for a variety of reasons. Were you able to run these apps manually instead of using the script run.py?

To debug, when you run an app and something fails you should get a file called crash.log in the directory scripts. You can check this file and see what failed for that specific app. Please note that we keep appending information to crash.log so delete this file before a new run. Thanks

Hi, can I use “lunch sdk_phone_x86_64-userdebug” or "lunch sdk_phone_armeabi-v7a-userdebug" instead of “lunch sdk_phone_x86-userdebug”? When I downloaded some apps, a line of instruction "Failure [INSTALL_FAILED_NO_MATCHING_ABIS: Failed to extract native libraries, res=-113]" appeared in the crash.log.

from crylogger.

Yes, you can run apps downloaded from the Google Play Store. If an app fails because of missing libraries, it might not be possible to run it on the emulator. I've never tried the target lunch sdk_phone_armeabi-v7a-userdebug.

You might need to increase the number of random events generated with Monkey because usually 100 is too low to execute some cryptographic APIs. If you don't find the log after the execution you can try to execute more events, e.g., 10k. Note that some apps require login credentials, thus it is more difficult to run them with Monkey.

Excuse me, if the tested apk is of ARM or x86_64 architecture, it may conflict with the architecture of the simulator(Because the emulator we create is x86 architecture.). We all know that for a complete apk, it is more difficult to edit the build.gradle file file and recompile the apk by reverse engineering. Then can you recommend some apk that you tested successfully, the apk I downloaded currently has this problem. Thanks！

from crylogger.

Hi, for many apps you can download the apks that target a specific architecture, e.g., x86. You do not need to reverse engineer the apps and recompile them. Alternatively as you suggested in your previous comment you can change the target architecture. Thanks!

Hi, If I run apps downloaded from the Google Play Store, what shoule I do to get cryptologs of these apps with CRYLOGGER?

from crylogger.

The process is similar to the app we provided in this repository. The only differences are that you need to download the app from the Google Play Store and change the number of random events. To download a set of apps, I used an apk crawler that used the Google Play Store website to download the APKs. Unfortunately this is no longer available... but you may be able to find something similar that downloads the app for the architecture you want to use. Thanks

Sorry, I mean what command should I enter. According to the instructions given, I will enter "python run.py --work_dir data --session emulator-", but the apps I downloaded directly from the Google Play Store in the given emulator will not provide an apk file. Many thanks!

If the app is already installed on the emulator, e.g., by using the marketplace, you need to modify the script to skip the installation step and find a way to provide the name and the package to the script. So you need to modify manually the Python script as it does not provide the functionality that you're asking.

Regarding the apps, I tested several apps. Please try some of the Google Play Store. If the installation is successful and the app works correctly, you should be able to get the log of the cryptographic APIs. If you don't find the log it means that the app has not been executed for enough time. In one of your previous screenshots, an app was running successfully, please try to extract the log from that one. The log should be in the directory /data/data/<app-package>/cache.

I hope this helps.

Hi! I also have trouble installing apps from Google Play Store onto the emulator. I have successfully run crylogger on the given example app and am trying to run it to test other top apps from Google Play Store. Here's what I did:

1. use chrome extension to download apk files from Google Play to my mac, and transfer the .apk file to the remote server (where the emulator is located) (app info: phone, x86, android 9.0)

2. Then I tried to do adb -s emulator-5554 install -g data/apks/voila-ai-new_27.apk, but I always got the error message saying "broken pipe (32)" as below

I have tried adb kill-server and adb start-server and restart the emulator multiple times (as suggested on some posts online), but it still did not work. Have you met similar problem before? Or do you have any suggestions on this? Thank you!

Hi, sorry I've never seen that error message before. I'm not sure what it is going on. Thanks.

No worries, thank you for you reply! I have tried several times more and it still didn't work. In this case, I am going to try to install Ubuntu and run this on mac to see what happens.

Many thanks for your patient reply and guidance!
I have already solved all the problems mentioned above.
Maybe someone added a necessary snippet code to the file "build.gradle" in his app so that the app can be installed in the given X86 emulator, but others did not do like this.
你好，我也发现了这个问题，适用于arm架构的apk在x86架构的模拟器上安装会出现错误，而且目前国内应用arm是主流，请问你是怎么解决的呢。
