SHA-1 is getting weaker, so we need to move IPS to SHA-256 as soon as possible.

Other than changing the code is there something else that needs to be done with the "RE" processes to make this happen ?

I'd like to try and do this as my first code contribution for IPS.

To: [email protected]

McDonald, Hawkes and Pieprzyk claim that they have reduced the collision
strength of SHA-1 to 2^{52}.
