Section 1 says:

   Hash algorithms are used by cryptographers in a variety of security
   protocols, for a variety of purposes, at all levels of the Internet
   protocol stack.  They are used because they have two security
   properties: to be one way and collision free.

It should say:

   Hash algorithms are used by cryptographers in a variety of security
   protocols, for a variety of purposes, at all levels of the Internet
   protocol stack.  They are used because they have two security
   properties: to be one-way and collision-free.

Notes:

Note the " one way and collision free." On the face of it, as plain
English, this is nonsense. In cryptographic terminology, I believe
the correct expression is " one-way and collision-free."
