greetings! I've got sensitive personal information on my flash drive (thumb drive) because of a passport issue; stuck abroad I'm sure I'd enjoy the beer if only I drank beer! I have found usb drives are like prisoners in those war films, always plotting their escape and sometimes succeeding. it would be bad if this one ran into the enemy camp! obviously I can just not store any sensitive data on the drive but are there any good encryption options? they would have to meet the following criteria: a) I must be able to read the files from Windows and Macs computers; b) I cannot install software on those computers. the best I can figure is put zip or pgp on the usb drive, maybe truecrypt?
