Well said. I particularly liked the part about the local media.http://blogs.msdn.com/ptorr/archive/2003/10/10/56253.aspx#56255Fri, 10 Oct 2003 11:52:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:56255Valery PryamikovYou are a good story teller, Peter! I enjoyed your story. However your analogy is not very good. Digital signature only protects content from modification, but wax sealing also provides means to alert occurrence of unauthorized access to the sealed content. The later doesn't have PKI analogy, and is very challenging to implement in local area networks (where it requires great deal of support from the OS and LAN infrastructure) and near to impossible for implementing on heterogeneous wide area networks. That is one of the reasons that nobody had success in implementing efficiently working Digital Rights Management system yet. -Valery.http://blogs.msdn.com/ptorr/archive/2003/10/10/56253.aspx#56256Fri, 10 Oct 2003 18:20:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:56256Peter TorrRob - who told you about this page?!? Argh! :-) Valery - thanks for the comment. I tried to make this point with my paragraph beginning "One thing that plain vanilla encryption doesn't give us, but that the seal does, is an indication that someone has read the message" but perhaps I didn't do a very good job. DRM is hard to do, and I don't believe anyone has a perfect story yet (at least not a pure software one).http://blogs.msdn.com/ptorr/archive/2003/10/10/56253.aspx#56257Fri, 10 Oct 2003 20:05:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:56257Eric LippertHey Peter, Sending wax seals through the mail doesn't work -- I've tried. The wax becomes stiff and the sorting machines destroy it. You need to have your wax-sealed envelopes delivered by a liveried footman.http://blogs.msdn.com/ptorr/archive/2003/10/10/56253.aspx#56258Fri, 10 Oct 2003 22:28:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:56258Peter TorrUnfortunately my footman was polishing the Roller and the manservant was exercising the corgi, so they were unable to deliver the letter for me. I'll have them roundly whipped for good measure.http://blogs.msdn.com/ptorr/archive/2003/10/10/56253.aspx#56259Tue, 14 Oct 2003 21:01:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:56259Alex AngelopoulosI love this. Peter, you are living evidence of why the "two cultures" concept of arts and sciences is a myth.http://blogs.msdn.com/ptorr/archive/2003/10/10/56253.aspx#63764Wed, 28 Jan 2004 11:06:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:63764Office Development, Security, Randomness...
