Title: MD5 and SHA-1 Collision Tutorial
Abstract:
MD5 and SHA-1 are well developed and popular cryptographic hash functions
used for various security purposes, including password storage and integrity
checking.  Both of these algorithms have been shown to be vulnerable to
collisions.  In this tutorial, collision attacks for both of these
algorithms will be presented and analyzed.  In addition, the implications of
these attacks on the development of future hash functions will be discussed.
