Is there a script that uses openssl to verify the certificates in the certificate chain or some tool?
openssl verify will verify / validate a certificate chain. I have also thought that https://github.com/DMTF/SPDM-Responder-Validator should have a standalone SPDM certificate chain validation tool, so that folks can validate their certificate chains to the SPDM specification without having to construct a full Responder.
Any other tool available? Have you ever verified it using openssl verify tool? Can you share an example?
Any other tool available?
Probably? Most folks use OpenSSL because it's free and comes pre-installed on a lot of Linux distributions.
Can you share an example?
libspdm/unit_test/sample_key/rsa2048>cat ca.cert inter.cert end_responder.cert > chain.cert
libspdm/unit_test/sample_key/rsa2048>openssl verify -CAfile ca.cert chain.cert
chain.cert: OK
