It sounds like a good idea, can't be too hard.  I would like to point
out that the vulnerability was oversimplified in the media.  From what I
have read, it requires that the cert was produced with "poor quality"
entropy.  Ben Laurie (of the OpenSSL team) posted a couple[1] of items[2]
on his blog about this.  In the comments of those posts, particularly
the second one, there is some more information[3] about the attack.
There's also a link to another blog post which describes exactly how[4] MD5
sigs can be made safe.  

I appreciate all the info.  I know the media over simplified, but
management does not get the technical details behind it and I have heard
from several people they have been tasked with verifying all their SSL
certs are valid and do not use MD5.  It is more about perception than
reality.  Just being able to verify would be nice.

Anyone working on a script to detect MD5 signed SSL certs?
