I am new to security and encryption. I want to store important information like passwords and pin codes so I don't forget them. So far I have been using LastPass but I would prefer a solution I control my self. From reading a lot on the net it seems to me that 7-zip with AES 256 encryption is the way to go.
But what about the temporary files while opening/editing the content?
The temporary files are being deleted (as far as I can see at least) but I guess deleted files can be recovered?
Here is the process I would use (suggestions fro improving it are most welcome!):
- create SECFILE.txt on desktop
- open, write, save/close
- right click SECFILE.txt, add to archive...
- type password, click Ok (SECFILE.7z is created same place, 7-Zip closes)
open SECFILE.7z, enter password
- hit F4 to open SECFILE.txt in Notepad, read, close or...
- edit (as you start typing a temp copy will be created)
- save/close Notepad
- back in 7-Zip hit Ok in pop-up to update archive
On Android (I want to be able to read my information on my smartphone too) the app ZArchiver works fine to open and read files.
My computer runs Windows 8.1 and the file system is encypted with BitLocker. My smartphone (currently a Samsung Galaxy S4) can also be encrypted and I password protect it with a pincode. But lets say somebody got access to my computer or smartphone. Would the temporary files be an issue?
TEMP files: Z-Zip (PC): C:\Documents and Settings\\Local Settings\Temp\7z#####.tmp ZArchiver (Android): /storage/emulated/0/Android/data/ru.zdevs.zarchiver/temp
