A company hosts a web server that requires entropy in encryption initialization and authentication. To meet this
goal, the company would like to select a block cipher mode of operation that allows an arbitrary length IV and
supports authenticated encryption. Which of the following would meet these objectives?

Can someone correct me on this…
shouldn’t the answer be CBC since it utilizes IV?
ECB doesn’t use IV.
I may be wrong on this.
The correct answer is B, GCM. Because it supports authenticated encryption.
