This is true. 

I am going to ask the hosting company to setuid gpg as
root. That should solve one problem (from gpg docs):

"This is necessary to lock memory pages. Locking
memory pages prevents the operating system from
writing them to disk and thereby keeping your secret
keys really secret."

But just out of curiousity, let's assume you are
running a shopping cart which takes credit cards and
passes them on to whomever approves them and you don't
_ever_ write this info to files. Aren't you also
vulnerable to someone being able to "snoop memory" on
your process for sensitive information?

I mean at some point some program on the server has to
take the customer's credit card, and that info is in
memory somewhere until you get the approval. Isn't
that true?

Thanks!,

Lawrence Kennon
