Webﬁnding a pseudo-collision, a free-start collision, and a near-collision whose deﬁnitions are given in Section 5, is called a certiﬁcational weakness. Presence of certiﬁcational weaknesses does not amount to a break of a hash function but is enough to cast doubt on its design principles. 2.3 Generic attacks Webcollision attacks can vary.
