Import ca.crt as a trusted certificate on OS X

###Change to CA working directory

goconf
cd static-content/localhost/cert.metadatacenter.orgx

###Locate the cacert file

Find out the currently active java version:

java -version

####Locate cacerts file

Locate the corresponding cacert file, based on the Java version (pick the cacerts that has the proper Java version in its path):

locate cacerts

You will need an up-to-date locate index for this to run. If you encounter the following error message:

WARNING: The locate database (/var/db/locate.database) does not exist.
To create the database, run the following command:

 sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.locate.plist

Please be aware that the database can take some time to generate; once
the database has been created, this message will no longer appear.

then you should create the index as follows (and wait until it is built; it is a background task, you won't be notified about its completion):

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.locate.plist

####Alternative way of locating the cacerts file

sudo find / -type f -name cacerts

###Import root cert

sudo keytool -import -alias metadatacenter.orgx -keystore /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/jre/lib/security/cacerts -file ./ca-metadatacenter.orgx.crt

The password should be changeit

###Useful, if mistakes were made

If you imported the wrong file, or you imported the proper file into the wrong certificate store, you can delete it using:

keytool -delete -noprompt -alias metadatacenter.orgx -keystore /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/jre/lib/security/cacerts

If you wan to see the list of certificates in a store, you can use:

keytool -list -keystore /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/jre/lib/security/cacerts
