KeePass portable for me. I don't use drop though as I don't trust it enough with my KeePass database file
I also use KeePassdroid for my android smartphone
Just how easy is it to hack the *.kdb files though?
I use the AES 128-Bit block cipher using 256-Bit key with 6000 encryption rounds
It can be done, but it is difficult enough and takes enough resources that unless you are hiding the launch codes no one is likely to try.
