Honestly, I searched through my old hard drive but couldn’t find anything useful. So, I decided to use some data recovery tools, and fortunately, one of them managed to recover a .gpg file—although it was restored with a random name. The file is 165 MB in size and has a .gpg extension.
I ran a full strings scan on it, and it was filled with keywords like “btc”, “wallet”, “xprv”, “priv”, and “key”. I also noticed the beginnings of old Bitcoin addresses. However, all the matches were small fragments—no complete sentences or full addresses.
Then I used the gpg --list-packets command to analyze the file structure. It showed that the file is encrypted using RSA (Key ID starting with 5EB…), with algorithm 3 and an encrypted data packet of length 6284 bytes.
