of course you need to keep this file in a secure place as well, because if you don't need keys, then anyone in possession of the file can brute force the password, right? (this assumes that the password you've chosen isn't random w/ non-alphanumeric chars, too long, etc.) ....then that requires another password for dropbox, etc..... it never ends if you start to get paranoid I guess.
yeah - if you start to get paranoid you will end in a mental institution :)
no, seriously, if you choose a good 'primary' password -it's ok. Choose somethimg around 10-15 chars and use digits, caps, smalls, special. But do it in a way that it's easy to memorize. There is a plenty of papers on how to do this around the net. But in short (and very paranoid way to construct password):
1. Get a phrase that is meaningful (for you at least);
2. Get first letter of the first word, second letter of the second word, third from the third etc. If there is not fifth letter in fifth word - use last one;
3. Substitute some of the letters with look-alike digits or chars: A for 4, a for @, l for 1, e for 3, s for 5, g for 9 etc etc;
4. Make second, forth, eight (or first, third, fifth) chars uppercase (if they are letters);
5. Done.
It sounds complicated but it isn't. It's easy. And soon enough you will be able to construct such a passwords in a seconds in your mind. :)
example:
'Someones screaming my name,
Come and make me holy again,
Im the man on the silver mountain'
1. Scyeedeeynmennern
2. sCyeEdeeYnmenNern
3. 5Cye3deeYnmenNern
Not very good example because all of these repeated characters but you get the idea. You can memorize it just singing Rainbow's 'Man on The Silver Mountain' to yourself :)
And don't go very paranoid. If you want to be very very very very secire - use retina-scan device or DNA tests before you give access :)
