Java keytool easy way to add server cert from url/port (for Windows)

I want to import CA certificate into a Java keystore. I found this answer with some Unix commands.

I understand that keytool works in Windows the same way as in Linux, doesn't it?

But what about openssl?

I installed openssl in Windows, then ran it and it works normally. But how can I replace a code below?

</dev/null | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ${HOST}.cert

Or can I replace openssl with something else?

Solution

  • Probably the easiest way is to use KeyStore Explorer. Just use the "Examine SSL" feature and then click on "Import":

    enter image description here

    Alternatively you can replace </dev/null | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ${HOST}.cert with manual steps. If you execute 

    openssl s_client -connect -connect www.google.com:443

    it will output something like this:

    depth=2 OU = GlobalSign Root CA - R2, O = GlobalSign, CN = GlobalSign
verify return:1
depth=1 C = US, O = Google Trust Services, CN = Google Internet Authority G3
verify return:1
depth=0 C = US, ST = California, L = Mountain View, O = Google LLC, CN = www.google.com
verify return:1

No client certificate CA names sent

    Mark the lines starting with -----BEGIN CERTIFICATE----- up to -----END CERTIFICATE----- and copy them into a text editor. Save it as [host].crt. Then execute the keytool command.

    If you want to automate these steps in a script, you'll have to install Cygwin or one of the suggestions in this answer here.
