## Message

```
Move PBKDF2 to a pwhash category, clarify what that category is

Password hashing functions are not general-purpose KDFs, and KDFs
don't have to satisfy the same properties as a PHF.

This will allow fast KDFs such as the HKDF construction to be in a
category of their own, while clarifying what functions are suitable
for using passwords as inputs.

```
