In cryptography, entropy refers to the randomness collected by a system for use in algorithms that require random data. A lack of good entropy can leave a cryptosystem vulnerable and unable to encrypt data securely. For example, the Qvault app generates random coupon codes from time to time.
In computing, entropy is the randomness collected by an operating system or application for use in cryptography or other uses that require random data.
