How can I encrypt a file before ftp'ing it. I am creating a text file
abc.dat and I want to encrypt that file with same name and ftp it
to a remote server. Please advise.

You can bypass the encryption of the file if you use sftp with SSH.

It will allow you to copy any file with encryption from point A to point B. It's a little slower than regular FTP but it keeps the ftpd from being exposed to the outside world.

If that is not a viable option, take a gander at pgp for encryption purposes.

Thanks for your prompt reply.
I am not a Unix admin and I have a very little knowledge of unix.
I am using a HP-UX B.11.00 A 9000/800 unix box.
How can I insall/use sftp with SSH. Please advise. Do I need any specific software to use sftp with SSH.

I have never used HP-UX, but I am willing to bet that if you do a Google search you can find SSH (or OpenSSH) available for HP-UX.

Once you have it installed and can use the ssh client to get into the machine, all you need is sftp or scp. It's pretty simple.
