How to view all password-protected posts?

I would like to change all of my password-protected posts into private posts.

To accomplish that, I was looking for a way to view all of my password-protected posts in the posts list, but there isn’t a filter for password-protected posts (there are filters for private posts and drafts though). Then I was hoping to batch edit them by changing their “status” to “private.”

What happened was: I imported my livejournal. During the import, I chose to turn protected livejournal posts into password-protected wordpress posts (instead of the other options, which included importing them into wordpress as private posts or drafts). I have now changed my mind and want them to be private. If I cannot batch-edit the “Status” of my “password-protected” wordpress posts, what is a better solution? Should I simply delete my database and re-import my old posts from livejournal, this time with the option “import protected livejournal posts as private wordpress posts” chosen instead?

Thanks!
