In a case you are investigating, you recovered an encrypted file. if someone in the past used an decryption key to decrypt the encrypted file, can that key be recovered from the machine? Suggest a tool for this task and specify which part of the PC (technical name) will target to recover such a key.
Notes:
1- The decryption key was never saved on the hard desk.
2- The key is more than 1000 characters of non-English alphabets with symbols and numbers (extremely strong password).
