I think we are good to continue as a "normal" 5D002 self-classification. Great if you will have a go, let me know if you would like me to help or review! See http://www.apache.org/dev/crypto.html#sources for svn details, linking to https://svn.apache.org/repos/asf/infrastructure/site/trunk/conten

RE: US Export classification & ECCN registration for encryption in commons?

Hi Stian, If we decide to go ECCN 5D002 self-classify category, do you have an idea that what I can proceed next? I saw you updated eccnmatrix.xml file for Taverna. Would you please help share where is the place of the file and who has the privilege to make an similar update for Commons Crypto?
