    Alright, 3 hours isn't a ton of time together but here are 100 hours of top-notch videos, lectures, and problems to help you learn all the crypto you want:

    First, my notes at https://crypto.prof.ninja/notes have the UD Capture lectures availble too: https://capture.udel.edu/channel/CPEG472%2BSPRING%2B2019%2BAPPLIED%2BCRYPTO/111929711

    (That's a 3 credit hour 400/600 level course that starts where you are and walks through everything.)

    Problems that went with that course: https://crypto.prof.ninja/ctf
