Entropy is a measure of randomness or unpredictability in a system. In the context of generating a private key, entropy ensures the key is highly random and secure. High entropy is crucial for cryptographic security, as it makes the private key difficult for attackers to guess or reproduce.
:: Matrix ::
We generate pseudorandom numbers 0-9, then plot consecutive pairs in a 10x10 matrix (with color according to pair frequency), continuously update the entropy measure, and display the histogram.
