Ask HN: Anyone have more information on latest Snowden tweet?

The tweet in reference: http://archive.is/sDyiK

(The tweet has since been deleted)

The 64 character hash from the tweet: ffdae96f8dd292374a966ec8b57d9cc680ce1d23cb7072c522efe32a1a7e34b0

Some are speculating that it may have been a dead man's switch, others that it was simply a file checksum for a partner to verify a file against.

There have been no more tweets from Snowden since that tweet was made at 12:14PM Aug 5 2016.

I'm generally concerned/curious as to what is going on and can't find anything solid.
