Ok I know in a way my request is self defeating on the security front but I'll try anyway.
I'm after some encryption / Steganoraphy software to create a small secure partion on removable drive (usb etc). That's the easy bit found plenty of this.
HOWEVER I would like the file (partition) to be able to be accessed without need for software on the host system and be editable and when closed re-encrypted. Ideally i dont want to run exe's on the host system although I am aware this may be the need.
In short I'm after a self decrypting / encrypting file / partition area on a USB drive with minimal need for exe's to run on the host.
I appreciaite holding the decryption / encryption key within the file presents a risk but the information is being protected mainly to prevent the casual individual getting to it. But it does require a little more protection than a standard file file password would afford.
Hope someone can help.
TT

Truecyrpyt may help even though you have to run an EXE on a PC to help you. On the pluys side it runs from the USB drive.

| Thanks, looked at Truecrypt and thought it may be of use. I am happy to use 'installed software' to create the files / volume initially but would prefer they were self-decryping and if then changed could self re-encrypt when closed. My reasoning is I want to be able to use the files on work systems and systems I visit occasionaly. Nearest I think other than Truecrypt I have found is Blowfish but again this requires an exe on the usb stick, it is however very small and considerably easier than Truecrypt. I will however re-visit truecrypt and trawl the manual to see if any of the options suit me better than the satndard. Ta Geof I

Blowfish is an encryption algorithm I *think* Truecrypt will make use of blowfish (personally I only ever use it with AES).
Truecrypt should run directly from the USB drive and is secure because you can set it up with a pass phrase / key etc. that you only have to remember 
Ultimately you are going to *have* to run an exe to perform the decryption I'm afraid....
EDIT: ah no, Truecrypt uses TwoFish as one of it's algorithms - which is based onBlowfish (a more modern variant). It too is free of cryptanalysis.
For Truecrypt on a USB stick go here: http://www.truecrypt.org/docs/ and fins "Traveller Mode" on the left. This works well for me for highly secret information / files so it should be fine for your uses
Cheers,
Tom

| Many thanks, Will look at this as it sounds like the best i'm gonna get. As an aside the blowfish I used of old was a program to allow file ecyption and decription used a variety of alogarithms and I seem to recall blowfish was actually one of them so i guess thats where the name came from. Thanks Geof

AH right 
If you look through some of the links on the Truecrypt site there are a few other options available that might suit you better.
I guess it's just a case of trial and error
Cheers,
Tom

| If you want an encrypted USB drive why not buy one, e.g.Sandisk for example? OK its only 128 bit encryption, and fully visible as a secured file, but it will put off most casual attacks. If your files require more than 128 bit encryption you probably shouldn't be putting them in your pocket!
