+1 for Dan's crypto1. I don't think crypto2 has been taught yet via coursera, as I've been waiting to take it and have seen it pushed back several times, and I've seen others say they'd been watching it get delayed for years. It does seem that Dan has been recording videos for part 2 in 2015 though (according to one of his students), so there's reason for hope that it might happen in 2016.
I finished Cryptography I in March 2012 and wanted to take Cryptography II ever since. Every time the announced time is close it gets pushed back by 4 months.
I think we'll know in a couple of weeks if its going to start on Jan 11th or not. If its not ready yet, it'll be pushed back by a month or two by mid December. That's how the previous postponements were done.
