/*

 * echainiv: Encrypted Chain IV Generator

 *

 * This generator generates an IV based on a sequence number by multiplying

 * it with a salt and then encrypting it with the same key as used to encrypt

 * the plain text.  This algorithm requires that the block size be equal

 * to the IV size.  It is mainly useful for CBC.

 *

 * This generator can only be used by algorithms where authentication

 * is performed after encryption (i.e., authenc).
