Lightweight portable encryption
6 answers - 1391 bytes -
Hi all,
I'm looking for opinions on a light-weight, portable encryption program.
What I mean by that is something that has the following characteristics:
* The program should be small enough to fit on (and run off of) a USB
flash-drive.
* I want to be able to encrypt 1 or more files with a reasonably strong
algorithm.
* I should be able to take the encrypted files/volume to another
computer and open the files with only the program and passphrase (ie,
the volume isn't limited to use on the system that it was created on).
* Needs to be able to work at least on Windows 2000/XP (S X/Linux would
be nice as well, but not really necessary for me at this point).
I carry my USB flash-drive with me quite often, and am terribly
concerned about leaving it in a computer somewhere or having it stolen.
While I don't keep top-secret documents on it, I do often have client
files that, while not damaging, could be embarrassing to lose.
I've started using TrueCrypt (www.truecrypt.org), and it seems to work
well. I can run it from my flash drive, copy the encrypted volumes
between computers, etc. However, I would appreciate opinions from other
people - opinions on TrueCrypt, or other programs with similar features
that they have had good/bad experiences with.
Many thanks,
Michael

TrueCrypt is a good choice.

An alternative is to use a good file-encryption program,
e.g., gnupg with symmetric key: gpg -c
or an archiver with real encryption support,
e.g., 7-zip (<http://www.7-zip.org/>).

Truecrypt has been the only thing I've used for the past 6 months.
I've been fairly impressed with the easy of use and the flexability of
the program. I think you've made a wise decision :P

I am new with this TrueScript program and encountering big problem.

1. I created a volume (E)
2. Mounted E and put some files in it.

Now, I can't even find the volume at all (not under Disk management for
WinXP either). And I the file size I allocated for this volume is gone
to. Any help in solving this is greatly appreciated.

Thanks,
David

Please disregard my question about the lost volume, I figured it out how
to recover it.

Thanks,

The only problem right now with TrueCrypt is that it _may_ *seem* to be
cross platform (Windows and Linux) but actual functionality is targetted
at Windows Users.

can still use it under Linux, but to create/alter/etc the TrueCrypt
partitions, one still needs to have access to a Windows Box.

However, I'm unsure if it's able to function using WINE/Crossover

The current version (4.2) can now do all that in linux. According to

4.2

April 17, 2006

New features:

* TrueCrypt volumes can now be created under Linux.
* Volume passwords/keyfiles can be changed under Linux.
* Keyfiles can be created under Linux.
* Volume headers can be backed up and restored under Linux.
* New Linux command line option: -u, , which can be
used to set default user and group ID of the file system being mounted
to the user and group ID of the parent process. Some file systems
(such as FAT) do not support user permissions and, therefore, it is
necessary to supply a default user and group ID to the system when
mounting such file systems.
* TrueCrypt volume properties can be viewed under Linux.

Improvements:

* Improved security of set-euid mode of execution (Linux).
