Best way to store 32 byte binary value with ability to index

[Matthew Jew]

Hello,

My application has a need to store 32 byte binary values, which I was  
planning to
store in a FixedBinary field.

However, in a recent post it was mentioned that one could use a  
FixedBinary field
to store values that "you do not need to index".

Does that mean that I cannot index (and therefore cannot quickly  
search on) a FixedBinary field?

If that is true, what is the best way to store this 32 byte binary  
value so that I might
quickly locate records?
