Explanation:

: As stated in the official CCSE NG Courseware: “A hash function is a one-way mathematical
function that maps variable values into smaller values of a fixed length” The size of the message is
made smaller in order to ensure maximum network performance. The shorter the message, the
less computation required, and the better the performance. See Page 7.7 of CCSE NG Official
Courseware. (VPN1-FW1 Management II NG FP-1).
