[LDM #QJP-576803]: LDM data transfer integrity

Joe,

Encryption, digital signing, and even compression of data-products could be 
done at the upstream LDM site via the pqp(1) utility prior to inserting the 
data-products into the product-queue.  For example,

    pgp --encrypt --sign data-product
    pqinsert data-product.pgp
    rm data-product.pqp data-product

And at the downstream site, the relevant pqact(1) entry could pipe the 
data-product to a script which would contain something like

    if cat >data-product.pqp; then
        if pgp --decrypt data-product.pgp; then
            # do something with verified file "data-product"
            rm data-product
        else
            # file "data-product" is unverified
        fi
    fi
    rm -f data-product.pgp

Regards,
Steve Emmerson
