comment Password protected zip opened in notepad
When did you create that .zip file? Did you use strong password or it was a time when you knew little and just used lowercase letters? If so, try bruteforcing it with some program like FZC. In modern computers, weak passwords are easily cracked.

@superuser :) take care when doing things "for fun" in security realms. You might end up without your data or without security...

comment Is it possible to prevent a physical attack on full disk encryption?
@ClayFreeman if you're worried that someone can take you RAM module out, also consider that he can stick some wires and chips and read all data signals traveling between CPU and RAM. If data is encrypted inside RAM chips, but is decrypted when leaves the chip and goes "on plain" on your motherboard, there's almost no advantage in having RAM encrypted.

@ClayFreeman :) good luck, and tell us if you find other solutions. And just take care on which side your concentrating your efforts: in general, attacks come from online (due to soft bugs and misconfigurations) and from inside job. Stealing hardware just leaves too many traces.
