WebWhat is entropy? In general, "entropy" means disorder or chaos. But entropy has a specific meaning in cryptography: it refers to unpredictability. Cryptographers will actually measure how much entropy a given set of data has in terms of the number of bits of entropy. Because of this, Cloudflare refers to the lava lamp wall as the "Wall of Entropy." Web• Data can have less entropy than the total number of bits, but not more. • Different length blocks of data can contain the same amount of entropy. • Identical length blocks of data can contain different amounts of entropy. This is a very important concept in cryptography, particularly when considering cryptographic keys and passwords.
