Penkr is a C++ port of ohyicong/decrypt-chrome-passwords. I made this because I wanted to show my family why they need a proper password manager and why not to store passwords directly in the browser.

Python isn't as straight forward as a standalone exe file and some dll files. So I decided to make this C++ port as I don't wanna go mess around installing Python on their PC. This project runs on 2 exe files, and libraries use 2 dll files or are linked statically, the rest is built into Windows with the C++ redistributable installation that most people already have installed.

The name consists of 2 parts.

The first part is Pen which comes from Pen-testing which also comes from Penetration Testing. But also, Pen is also what is used to describe Pen-drives which is something I carry with me all the time, to both run portable Linux on any machine, as well as having most of my files with me.

The second part is Kr which is the first two consonants in my nickname.

This repository is a bit tricky to setup but premake should get most of it done for you.

• Penkr is using Visual Studio 2022. If you use another version of Visual Studio, you need to edit scripts/Win-GenProjects.bat and change vs2022 to whichever IDE you use. For a list of all IDEs supported by premake, visit Premake's website.

1. Clone the repository. Remember to clone recursively git clone --recursive https://github.com/Kirdow/Penkr as it does use a submodule for Crypto++.
2. Open scripts/ and run Setup.bat. The python script should go through and install all the requisites needed in order to build and run the project.
3. Inside Penkr/vendor/cryptopp there is a file named cryptlib.vcxproj. Open it using Visual Studio.
4. At the top for the build, select Release and x64.
5. In the project list, right click cryptlib and hit Build.
6. Wait until the build finishes.
7. At the top for the build, select Debug and x64.
8. In the project list, right click cryptlib and hit Build.
9. Once the build finishes, close Visual Studio.
10. Now go back into the repository folder, and open Penkr.sln using Visual Studio.
11. At the top, select either Debug, Release or Dist, then under Build, click Build Solution.
12. Now in the repository folder, your binaries will be in the bin/<config>/Penkr directory.
13. In order for PenkrClear.exe to work with Penkr.exe it has to be moved to the same folder. Simply navigate to bin/<config>/PenkrClear and move PenkrClear.exe into bin/<config>/Penkr.
14. Some DLLs aren't automatically copied to the binary folder, in case you're missing DLL files after the build, you'll find their locations below.

• Run Penkr.exe to fetch the passwords. Current supported browsers are listed below. Once it's finished it will save all passwords to pass.csv in the current working directory.
• pass.csv contains passwords across all browsers stored in columns of index, url, username and password. Note that for usernames and passwords containing a comma the format may break. URLs containing a comma is handled though.
• Run PenkrClear.exe to remove the pass.csv file. This does the same as just deleting it normally except it doesn't stay in the recycle bin. I made this in order to avoid the risk of having someone getting the file back via the recycle bin. It still risk being reinstated with disk recovery apps though.
• If PenkrClear.exe successfully removes the file you should hear a recycle sound effect. Any other sound indicates that the file couldn't be removed. This could be due to the file being open in something like Microsoft Excel or similar.

Only Chromium based browser are supported. The currently supported browsers are:

• Google Chrome (Chromium, Chrome, Chrome Beta & Chrome Canary)
• Brave
• Opera (Opera & Opera GX)
• Microsoft Edge

This list may be outdated at some points, so check directories.cpp to see the most up to date list currently in use.

• Crypto++ (see their website and their github) - This one is statically linked and shouldn't require a DLL. But its .lib file is located in Penkr/vendor/cryptopp/x64/Output/<config>/cryptlib.lib.
• SQLiteCpp (see their website and their github) - This one is pre-compiled for the repository, and is located in Penkr/vendor/sqlite/ with the .lib files at lib/sqlite3.lib and lib/SQLiteCpp.lib, as well as the .dll files at dll/sqlite3.dll and dll/SQLiteCpp.dll.
• Crypt32 (see Microsoft Docs) - This one is used the decrypt the initial key as is included with your Windows installation. This is simply linked as Crypt32.lib and is located at C:/Windows/System32/crypt32.dll.
