C++ Decrypt chrome cookies

I need to read Chrome cookies in C++, but Chrome encrypts them all. All the other methods of decrypting the cookies I have found are now no longer working, anyone know the latest way to do this?

Please see for information how Chrome 80+ protects cookies: https://xenarmor.com/how-to-recover-saved-passwords-google-chrome/

New Chrome version (v80.0 & higher) uses Master Key based encryption to store your web login passwords.

Here is how it generates the Master Key. First 32-byte random data is generated. Then it is encrypted using Windows DPAPI (“CryptProtectData”) function. To this encrypted key, it inserts signature “DPAPI” in the beginning for identification.

Finally this key is encoded using Base64 and stored in “Local State” file in above “User Data” folder.

Or here: Did changes in Google Chrome 80 weaken cookie and password encryption?
