[quote=Coursera’s “About Us” section]Coursera is an education company that partners with the top universities and organizations in the world to offer courses online for anyone to take, for free. Our technology enables our partners to teach millions of students rather than hundreds.[/quote]
They currently have 2 Crypto classes:
One made out of 2 different modules (crypto1 and crypto2, lol) from Stanford Uni
and
One from University of Maryland
Now I’ve been watching the lectures (video lectures FTW) of the Stanford’s first module in my spare time, and it appears to be quite interesting.
If you are interested in stuff like that and have the time, this is their site. It requires an account, but everything is free.
Of course, there’s other stuff to be learnt from that site, so look around and enjoy!
