I know someone else already mentioned it, but I use a 128MB drive and partitioned it into 2 partitions. The first is a vfat for use with windows and the second is ext3. I store my key on the second partition. The drive will show up as a SCSI drive, most likely /dev/sda. Backup everything currently on it, then run 'fdisk /dev/sda' and repartition. Works like a champ.

This method has the added benefit of a little security through obscurity. If someone gets their hands on the drive, they'll most likely stick it in a windows machine and they'll never see the second partition. Please notice I said a LITTLE security, it is very little.

I was thinking of getting a USB keychain flashcard to store (among other
things) my private key(s). However ssh requires that your private key be
400. I assume the USB keychains are vfat, in which case you can only set
the permissions to 444, and ssh won't accep the private key (tested on a
vfat floppy).


Presumably I could put an ext3 file system on there, but then I won't be
able to use the device to transfer files to a windows machine (which
admittedly I don't do a whole lot, but would be useful to be able to do).


I understand that you're not supposed to reformat these devices a whole
lot, and that you should use cramfs if you're going to reformat them.


Do people store their private keys on these USB keychains?

Can someone straighten me out?

Thanks Joe
