When a game encrypts its network packets or asset files, the encryption keys in RAM have near-maximum Shannon entropy (Entropy > 7.95 out of 8.0):

import math
def shannon_entropy(data):
    if not data: return 0
    entropy = 0
    for x in range(256):
        p_x = float(data.count(bytes([x]))) / len(data)
        if p_x > 0:
            entropy += - p_x * math.log(p_x, 2)
    return entropy

Scanning memory pages with a 32-byte sliding window highlights 256-bit AES keys instantly!

Shannon entropy scanning is how anti-malware tools detect packed sections and crypto keys. Super elegant technique.
