[openssl-users] Verifying the sha1 of fipscanister.o with what is embedded in libcrypto.so

[Satya Das]

Steve,

How does one get a hold of the embedded signature in libcrypto.so ? 

Thanks

Ummm, because the vendor is the one who created the validated module.
Only that vendor can know for sure how the module was created, because the FIPS 140-2 requirements have non-technical procedural elements (think of those as ideological or spiritual elements).

Note that in this context "vendor" refers to the entity that created the validated module and submitted it for FIPS 140-2 validation. The company that uses the FIPS module in their product is a "user", not a "vendor", with respect to the validated module.

But it necessarily always comes down to a vendor document, for *any* validated module, not just the OpenSSL FIPS module. I've tried and failed now several times to articulate why that is so and can't think of any new way to present it, but it is simply not possible to do what you want; there is no such thing as a magical pixie dust detector. We cannot make one; no one can.
