howtos:how_do_i_verify_a_certificate

Use the verify option to verify certificates.

openssl verify cert.pem

If your local OpenSSL installation recognizes the certificate or its signing authority and everything else (dates, signing chain, etc.) checks out, you’ll get a simple OK message.

$ openssl verify remote.site.pem
remote.site.pem: OK

For this to work openssl needs to have access to the CA that issued the certificate. Otherwise you will get an error like:

error 2 at 1 depth lookup:unable to get issuer certificate

To import CA certificates see here: Import CA certificates for openssl to use
