If you have to handle sensitive files, your whole system should use full disk encryption. Creating unencrypted plaintext file and later deleting it will not erase the sensitive bytes from the actual storage device! If 7z removed those temporary files, it would appear less leaky but it would still leak sensitive data nonetheless. | |
