Hi,

I'm not able to find any API to retrieve at runtime the hash of an assembly.

1/ is there any existing API (I might not have looked in the correct
namespaces/classes) ?

2/ if not, why is'nt there any ? any security implication ? is it planned to
have one in .Net 2.0 ?

Note: I know that I can compute the hash manually (using interop or not).

There is no API to access this information in v1.x or v2.0 of the
framework. Out of curiousity, what is it that you want to do with the hash?

Hi Shawn. BTW, Shawn shows a native way to get that info, IIRC, on his
blog. One reason I have wanted that info before is to just a do a quick
runtime check that it is *not all zeros (i.e. someone changed it to delayed
signed and set assem to skip verification checking.)
