• chrome - click on site icon left to address in address bar, select "Certificate" -> "Details" -> "Export" and save in format "Der-encoded binary, single certificate".

2. Now you have file with keystore and you have to add it to your JVM. Determine location of cacerts files, eg. C:\Program Files (x86)\Java\jre1.6.0_22\lib\security\cacerts.

3. Next import the example.cer file into cacerts in command line (may need administrator command prompt):

keytool -import -alias example -keystore "C:\Program Files (x86)\Java\jre1.6.0_22\lib\security\cacerts" -file example.cer

You will be asked for password which default is changeit
