[Cryptography-dev] well maybe not - what to import

[Robert Moskowitz]

Thank you.

I have spent much time reading the docs and testing things out.  I have 
succeeded to a small extent and have gotten some of my goals met.  But I 
hit a wall and am really too tired at this point and really should just 
shutdown and not ask for help.

I actually had just found this part that you point to.  I read through 
it earlier in the week, and did not see how it fit in to what I am doing 
and my old brain just forgot it.

So, have a good weekend and I will come back to this fresh and will be 
more diligent in rerereading the docs.
