The age one becomes a legal adult in the US is largely the age at which most children are considered adults in the world. A few countries set this age lower, but in most of the Western world, one is considered an adult at 18.

Using Symmetric Ciphers for MACs â¢ can use any block cipher chaining mode and use final block as a MAC â¢ Data Authentication Algorithm (DAA) is a widely used MAC based on DES-CBC â using IV=0 and zero-pad of final block â encrypt message using DES in CBC mode â and send just the final block as the MAC â¢ or the leftmost M bits (16â¤Mâ¤64) of final block .
