PGP query with SDA

Hi
I have a requirement to have a script which will encrypt a file on my HPUX server in such a way that the receiver of the file only has to enter a passphrase to decrypt (no swapping of keys, etc.) Ideally, I want to use some free software to perform the task.

From what I have read so far, the way to do this involves encrypting it using PGP Self Decrypting Archive (SDA) which allows users to send conventionally encrypted files to people who do not have PGP installed.

However I don't know what tool to use on a HP-UX platform to achieve this. GnuGp might be the way to go, but I don't know if it supports SDA or how successful it is on HP-UX.

All advice welcome
TIA

The default symmetric cipher used is CAST5, but may be chosen with the --cipher-algo option to gpg(1). -s, --sign Make a signature. See gpg(1). -r, --recipient USER Encrypt for user id USER. See gpg(1). -u, --local-user USER Use USER as the key to sign with. See gpg(1). --list-archive List the contents of the specified archive. -o, --output FILE" Write output to specified file FILE. --gpg GPG Use the specified command instead of gpg. --gpg-args ARGS Pass the specified options to gpg(1). --tar TAR Use the specified command instead of tar. --tar-args ARGS Pass the specified options to tar(1). -h, --help Output a short usage information. --version Output the program version.
