I am not a coder. In fact I pretty much stopped writing code in the
'80s. I DID some programming in B on Honeywells. The only place where
B escaped Bell Labs. I never got to C; moved on to other IT support
work, then to coding standards in English...
I have some limited scripting skills.
So as much as would like to contribute code, with maybe 2 years to
retirement, I am not going to pick it up. But who knows, maybe I will
take a C programming course as part of my retirement activities.
I kind-of slept on this issue. I know that I can convert a PEM cert to
DER, but I have been thinking about 'what of the other portions, like
the keypair file?' I woke up a little clearer head, and realized, that
a truly constrained device won't even bother with DER, but just store
the raw keypair. So doing the creation all PEM and converting what is
needed as DER to DER may be a realistic approach.
thanks for your help on this.
