With all the enthusiasm for crypto... Anybody fancy doing

https://www.coursera.org/course/crypto
https://www.coursera.org/course/crypto2
https://www.udacity.com/course/cs387

...the udacity one can be started at any time, and contains such fun games as

"A poor cryptographer reuses a one time pad.  Here are 2 cipher texts encrypted with the same key.

and

Decrypt the texts"

Long winter nights and all that... But it is interesting to get a better idea of the underlying crypto primitives ( <- good name for a band ? ) that we are trying to use and the attacks against them.
