#Openssl verify certificate and key plus

That would build the chain (actually validating it also as a side-effect) and create a PKCS12 containing only the privatekey and leaf plus valid chain if successful, but give an error and create no output if unsuccessful - i.e.

Instead of manually building and checking the chain and then using it, you could use openssl pkcs12 -export -chain and provide the possible chain certs as (or in) -CAfile and/or -CApath. As part of the process I double check that the certs I've downloaded from the issuing CA are correct and that they're in the right order before passing it to openssl to mint the PFX.Įxcept for the 'bar the root' part, you could reverse this workflow. I often create PFX files with the entire certificate chain (bar the root) for distribution within the company I work for. If you have multiple certs for the same subject and issuer it's harder. If you have certs for the same subject from different issuers, looking at the next cert's name (except on the last, which is selfsigned unless you also use -partial_chain) is enough. If you only have one cert per subject, that's fairly easy. In 1.1.0 up if it succeeds and you also specify -show_chain, it displays the subject names of each cert - which may or may not be enough to identify them. OpenSSL is a pure commandline product with no GUI, although of course you could use the library part (libcrypto) and write your own GUI.įrom commandline, openssl verify will if possible build (and validate) a chain from the/each leaf cert you give it, plus intermediate(s) from -untrusted (which can be repeated), and possibly more intermediate(s) to a root (or anchor) in -trusted or -CAfile and/or -CApath or the default truststore, which is usually determined by your system or build but can be overridden with envvars.

I can't help for other Mac tools including native.

#Openssl verify certificate and key how to

So to be clear, I'm questioning how to view the chain of a certificate I am working on locally on my computer. As part of the process I double check that the certs I've downloaded from the issuing CA are correct and that they're in the right order before passing it to openssl to mint the PFX. So is there a way to view a certificate's chain whether it be text or an image using openssl or native Mac tools? I also haven't figured out a way to show the certificate chain using openssl either, for example, the following command openssl x509 -in certificate.crt -text does not show a hierarchical chain - only the issuer. However on a Mac, this is how it shows the same cert in Keychain Access.Īs you can see, it doesn't have a nice hierarchical view that makes it easy to identify the certificate chain that Windows or certutil shows - at least not to my (possibly) untrained eyes. (okay it's inspecting a pfx but you get the point). See screenshot as an example.Īnd here it is again in Windows, but using the certutil tool. The way Windows displays certificate details is very succinct. I use a mixture of Windows, Linux, and Macs and have noticed big differences in how each OS shows certificate details using the default tools available in each.
