Ask Slashdot: What's the Best Way To Preserve a "Digital Inheritance"?
First time accepted submitter ron-l-j writes "The last few months a digital inheritance idea has been floating around in my head, and I am sure the thought has crossed your mind as well. With Google talking about the inactive account program it made me wonder, how do I make sure my children get my iTunes, and amazon movies? I have plenty of mp4 movies on my server that will just set itself to admin with no password after I do not log in within a 6 month time frame. But what about the huge amount spent on digital content every year? What's the best way to make sure your "digital inheritance" gets passed down?"
Any of it.

... in a manner of speaking. This is a well known problem in crypto.
My way: all of my passwords and secret documents are in an encrypted folder which I update along with my will. Included are final farewells, secrets, where the bodies are buried, and so on. The key is split (look up PKI key splitting) into 5 parts. My girlfriend, father, buddy at work, and two of my friends each have a part. For security reasons, those are just examples. Four of those parts together are required to unlock. At my death each one turns in their part to the executor of my will who already has instructions on how to get it put together.
It is not a good idea to naively split a 10 char password into two 5 char pieces, and assume that brute force will be necessary to guess one of those parts. That is a very dangerous assumption if you are not an expert with the particular algorithms used.
