Hello Ethan, I am tweaking the centos rpmspec to use my fips object module. That seems to be downloading source tar ball, patching etc.
Please note that the sha1 of the so is not so interesting as the embedded sha1 check inside so (when one calls FIPS_mode_set). Essentially if I can get the embedded sha1in the so, I can compare that with the sha1 I have as part of the object module I have built. I am assuming the embedded sha1 is that of fipscanister.o. Hope that makes sense ? Thanks.

It seems that it would be pretty non-trivial if not impossible to pull a .o file from a .so in the exact same format that it went in, such that you could check the hash. Being able to check if a .c file is in the same state in the .so afterwards seems pretty much impossible given all the things that would change in the code with compiling and linking in between the .c state and the final .so state.

I have built a fips capable openssl shared object (.so). I also have the sha1 hash of the fipscanister.o in a file called fipscanister.o.sha1. I also have the sha1 hash of fips_premain.c in a file called fips_premain.c.sha1. In order to make sure the build is good, I want to make sure that the .so was indeed built with these versions of fipscanister.o and fips_premain. Is there a way to do this ? I am on centos 6.6 x86_64 and linking to object module 2.0.11 from openssl 1.0.1e with patches.
