Many people may already know this or not but my question is, what's your point in sharing this OP?. Is it related to this one which also mentioned trial https://bitcointalk.org/index.php?topic=5484211.140 or another thing. It would be best if you tell something for others to understand what you are trying to do especially other newbies like this. As you can read in the quote, it is an archive of satoshi and sirius's private correspondence although it is also explained that it is incomplete that means sirius is uncomfortable to share all of it and doesn't have back ups as stated in the quote.
