That article certainly covers a lot of ground which i've yet to completely
get my head around. However i did focus on the XML encryption example section
which seems to outline exactly what i want to do.
I'm new to the cryptography side of thisngs and still have a question
relating to this.
The example sets an RSA variable 'billingKey' to the value returned by the
getBillingKey() method. Hypothetically would the value returned by this
method always be the same or is it random? I ask because i can't help but
feel my initial problem is caused by something like this. As i said before
though, i'm really not confident with cryptography yet.
Thanks for your quick response,
Grant
