A lot of you are missing the main point from the original post. You can NO LONGER create and edit a encrypted note in Evernote. Prior to the "New" version you could. For years you could. Evernote has taken away that feature and, currently, does not have published plans to bring it back. Existing notes with encrypted data in them cannot be edited, unless you want to turn the feature off.
That is what is frustrating. That, superb, feature was available for years, without having to export or do anything else outside of Evernote. As the users who have used the encryption are saying, bring THAT feature back.
