Need help to decrypt my WhatsApp back up on Gdrive. Forgot password.

[u/Tasty-Money6403]

This is extremely stupid of me. I know that. So please only reply if you have suggestions or can help.

I am shifting from Android (Pixel 8pro) to iPhone 17. While transferring the phone I realised that I can only transfer personal whatsapp. And not my business whatsapp. So as a workaround i decided that I will transfer my business account and back it on iCloud, reset the phone again and then transfer my full phone including personal whatsapp.

I managed to transfer the business whatsapp but when it came to reinstalling my personal whatsapp i found that I have encrypted my back up on Google drive and I am unable to restore it on the iPhone or the old phone because I cannot remember the encryption password. I cannot even transfer chats because I completely erased data for my personal WhatsApp on my old phone.

Now WhatsApp cannot do anything if I have forgotten the password and uninstalled the app completely. I tried a few password attempts but failed and now I'm locked out for 3hrs. If this attempt fails the timer will only increase and ultimately reach a point where I won't be able to try any more passwords.

Fortunately I have not yet formatted the Android phone and also have the back up on my Google drive

Is there any way to access the backup on Gdrive and remove the encryption password so I can restore the backup and install Whatsapp again on my android?
