Regarding the encryption each one of the encryption methods are separate, each of them is not related but different
And about the QR code it has the public and private key there

Hello ,
Probably is the most common topic but i couldn’t find an answer by reviewing post topics .
1. I use to mine bitcoin back in 2010,
2. I have transferred the rewards to bit coin core wallet. Then i spread it to few addresses within 2 wallet.
3. I have encrypted all information in few ways and format my hard disk (windows 7)

    - encryption 1: encryption of all files with encryption software which I have no clue which one I was
( I have few files which I suspect to be key file and container ) maybe using VM

    - encryption 2: files made with paint with the QR of every address in the wallet
                          - same with: word, PowerPoint, photoshop, excl. the files as been corrupted by removing    header of file and change of the extension

     - encryption 3: the bin folder with the files inside (but I’m not sure about it)

* I have protected many windows files and information ( basically all the windows folder) if I need to restore the user somehow
* if I remember right part of the transduction I did while the wallet is closed

Thank you all so much
