I'm using Yahoo mail to send emails on Linux MDK 9.0.


Some files that I attatch in my emails to people running MS-windows I would like to be able to compress and put a password on that file so that only that user can open the compressed file for viewing.

Winzip has this capability for MS windows and I was wondering if there was something similar in Linux that can do this and at the same time allow MS windows users to read that file from the linux machine?

Thanks,

I have used winzip to unzip a tar.gz file and as for password protection you can use a plethora of encryption tools to password anything you want in Linux. I use gpg and it works great but the person on the other end needs it as well.

here is an example of how you compress and encrypt a file:

tar -cf music.tar ./music/

this gives you an uncompressed tarball called music.tar, this is just a handy way of combining multiple files.

now you can encrypt and compress it with gpg like this:

gpg -c music.tar

this will ask you for a passphrase. The passphrase is all that is needed to decrypt this file.

gpg automatically compresses files with the zlib libraries which are used by gzip. gzip files are readable by winzip so if you want to forego the encryption you can just compress the file and it will be readable by the person on the other end as long as they run winzip.

I hope that helps,

Most Linux distributions that I am familiar with include a zip utility -- a virtual (and improved) clone of the PKZIP of DOS/Windoze fame. Try the command: man zip on your system, and see if it does what you want (compression/password protection). I have used this utility extensively to exchange files with Windoze users, and have never had a problem with incompatability.

Hope this helps.

You may have to install it from your Drake CD.But you should have it.

Thanks everyone.


I've got more than one way to do this now.

Thanks,
