The answer is “Yes” you can learn Cryptography from these videos, but honestly you are going to need a real degree to do the real stuff. You can find out that number theory and probability theory are used.
Their video says, “a lock is only as strong as its weakest point” and suggests that conceptually codes may be reduced to fingerprints. I learned its called Frequency Analysis when you...
