Thanks for the replies,

I need to switch out of Digest mode so I can be more punctual in my =
replies.=20

As far as the reason for the SDA's, it's not really my idea. We do =
booking engines and 3rd Party portal connectivity for hotels (3rd party =
portals are like Expedia, Travelocity, etc). One of our partner =
companies is responsible for broadcasting each hotel's rates and =
availability to these portals. I communicate the date to them through =
files that our systems FTP back and forth. Their system makes the files =
intp an SDA. I can decrypt it successfully using the pgpreader they =
provided, but I need to be able to create a similar SDA when I create my =
file that I upload to them. I an not likely going to be able to change =
their system. I was hoping to find a linux based open source pgp =
implimentation that will do SDA's for me. I understand the security =
risks, but I'm not really approaching this much from a security =
standpoint, but from a need to match the broadcast specification. =
There's really no sensitive data in these packets so I'm not sure why =
they even bother encrypting them. If gnupg doesn't support SDA's does =
anyone know of another method of producing them short of buying the =
commercial PGP version?

Thanks,=20
