Anyone know of a Linux equivalent of this type of encryption program ...
send secure attachments by e-mail without worries. The receiver of an e-mail with an encrypted file will only need the right password and a browser to decrypt the e-mail
Your data is converted into an encrypted html file which you send by email, the "killer application" is the recipient does not have to install any software : the decryption takes place in their browser via javascript. So it is independent of OS.

I hoped there would be a Linux version somewhere of the encryption program.
If anyone knows of html encryption like that which runs on entirely javascript that would be ideal, (i.e. both encryption and decryption in the browser).

I would love to find a JAVA based encryption which would allow me to encrypt a directory and give me the ability to decrypt it by typing a password into a browser from any OS. So far, the only thing that comes close to this is "tiddlywiki" The problem with tiddlywiki is you can encrypt within the ap and open with any browser, but i will not allow folders to be included in the portable wiki.
this sort of thing, (attached), but like linuxbear says, capable of handling folders (directories).
(BTW to decrypt click on "Decrypt" below the pink box and the plain text appears in the green box).
tar -czf dirname.tar.gz ./dirname
bcrypt dirname.tar.gz
pretty sure tar and bcrypt are cross platform
Check out my [url=https://github.com/technosaurus]github repositories[/url]. I may eventually get around to updating my [url=http://bashismal.blogspot.com]blogspot[/url].

So the Truecrypt file, which is encrypted, is encrypted again*.
A belt and braces man like myself: would you like to borrow my tin-foil balaclava ? :¬)
No, the clear text is typed and encrypted inside the truecrypt container (the resulting GPG file inside is a temporary issue, as it is of no use to YOU, unless you wrote it to yourself).
This keeps the clear-text encrypted (not visible on the regular partition, even if deleted).
The side effect generally is that the GPGed version is also inside, but you can delete that after sending (and it allows you to keep a clear-text copy of what you sent).

I am already using encrypted documents, PDFs and encrypted zip files on my pendrive. The problem is that this requires the installation or existence of installed zip and office suite applications on any machine that the drive is plugged into. The great thing about tiddlywiki is that it can be opened on any machine that has a browser installed. Tiddly will not encrypt folders, but does encrypt itself otherwise. This can probably be done inside an HTLM app, but I do not have the time to learn JAVA. The idea here is, plug into any machine, get stuff.

I may have got the wrong end of the stick again, but I’m sure Truecrypt has to be installed on the recipient’s computer for them to be able to open it.
I don’t think Truecrypt do a self-extracting option, 7-Zip does, but self-extracting files are OS specific.

Barkin, yes you are correct recipient needs Truecrypt as well.
