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.

Use of SHA-256 is going to require moving to Python 2.6 (bug 5573).

I don't understand why. Especially since in the same file there is already use of OpenSSL functions and OpenSSL provides SHA-256.

also depends on nailing down the reorganization of the depot directory
layout and the client-side download cache layout (bugs 7276, 7960).  So
it's a bit more than a couple lines of code.

Thats what I feared!

This is all stuff that we'd been planning on tackling for 2010.02, though I
think we could probably use your skills better figuring out all the details
of the manifest signing plan.

Given the above I think it is probably best to deal with this as part of the move to signing and when that is done change the default to be sha256.
