On August 16, 2013, WikiLeaks released on FaceBook a 349 gigabyte file labeled "insurance", that the public can download. While the file can be downloaded, it cannot be opened without the key, which WikiLeaks has not released.
A Time journalist, Michael Grunwald posted on Twitter, "I can't wait to write a defense of the drone strike that takes out Julian Assange. However, it was later deleted after multiple other journalists responded on the statement.
From time-to-time, WikiLeaks releases insurance files "to nullify attempts at prior restraint", as noted on Twitter from the WikiLeaks account.
No one outside of WikiLeaks knows for sure what is in the files, but the most popular ideas are that it could be the content that Edward Snowden downloaded, which he captured from the NSA, though that file should be considerably larger than the file posted, unless it is excerpts.
Tom-Eric Halvorson wrote that the passwords will not be released "unless something happens to specific individuals associated with WikiLeaks".
Several posts to the Facebook page indicated this was a challenge to hackers everywhere as there are posts indicating they are attempting to crack the code.
One part of the asylum agreement Snowden has with Russia is that he not release any additional damaging information against the U.S., from where he is currently a fugative and is wanted on charges of espionage.
Although Snowden sacrificed U.S. freedom for his statements, it was not for nothing. President Obama has called for regulations on how the government collects information, specifically for the NSA.
