Tonight I will be doing a presentation on Block Encryption and IVs at the Atlanta C# User Group. I have been scheduled to do this for months now and meant to blog about it a few weeks before today. Apparently I forgot to, but on the slight chance someone reads this and can make it, the user group is at Microsoft’s new offices in Alpharetta. It starts at 6 and my presentation is from 7.15 until 8.30.
