Subject Re: Definition of "provides bindings" for OpenSSL
Date Tue, 01 Nov 2016 20:49:30 GMT
Having dug through various archives, it seems like "provides bindings"
means any kind of linkage with a crypto library like SSL. So, I'll just go
ahead and add Kudu to the ECCN matrix and go through the notification
process to unblock our dev work.

The suggestion to update the FAQ still stands, though, to save future
projects the confusion.
