The test uses trusted certificates and checks no warnings on the weak algorithms to address the requirement described in the bug. I believe it does serve that purpose, and looks legitimate to me. There could be different ways of testing a functionality, and please let me know if there is a problem with the current approach.

I just meant that the keytool commands generating root.jks and root.pem are exactly the same and there is no need to recreate it.

It’s the ca (intermediate) cert needs to have it in this test scenario. I intended to leave it out in #160 to distinguish between server and ca certs.

OK.

Then how about we add a new command before line 155?

    kt("-importcert -file ca.pem", "ca.jks").shouldNotHaveExitValue(0);

This would prove the "-trustcacerts" on line 155 is really useful.

Same question as above.

There is no need to copy over the system cacerts, just make sure the file is created with the JKS storetype. We are thinking of upgrading the storetype of cacerts and it's nice to do this at a single place so we can modify it easily later.

It turns out that its caks.size() is zero detected at establishCertChain() in keytool/Main.java after root cert has been imported to that cacerts. At this point I’d like to suggest a separate bug be filed to cover the cacerts enhancement that you suggested.

I meant creating the cacerts in one method, something like

   void createCacerts(String ks, String... crt);

and you can call createCacerts("mycacerts", "root.crt") to create it. The method can call KeyStore APIs and not keytool commands.

BTW, what does caks.size() == 0 matter here?

Thanks,
Max

This enables keytool to use the trusted certificates when verifying untrusted artifacts that are signed by CAs. It also incorporates Max’s change that consolidates the code to get the default location of cacerts keystore.
