Encrypt and ftp using peoplecode

[MGW]

Hi,
I need to encrypt and ftp the files to ftp server by scheduling weekly. I have been doing this manually using gnupg encryption tool and windows ftp. I need to encrypt and sign the files. Can anyone tell me how can I achieve this using peoplecode or any peopletools? I have a clue of executing DOS command using peoplecode, but it is not working for encryption as the DOS command for encryption is interactive. Any help on this is greatly appreciated.
Thnx,
MGW

We are using a command line call to encrypt files using
GnuPG (http://www.gnupg.org). We store the users public in a keyring and the
public key ID on a database file.
to store the public key (this is done manually from the command line)
gpg --import "<path>/<key name>"
to encrypt a file using the public key ID (program generated command)
gpg --batch -ea -v --default-recipient "<key name>" -o <outputfile name> <input file name>

How do I upload a web page I created in notepad to my website using FTP? I'm clueless when it comes to FTP servers. The company sent me the FTP server with the files. Do I just need to upload the notepad document using an FTP client and it will replace the old files and show up on the site?
