Adding crt to Java cacerts

Adding crt file allows Java to access your self-signed ssl site without doing something like Insecurity HTTPS Connection.

Assume the location of your Java JDK is in C:\Program Files\Java\jdk1.8.0_131\. The following steps add the crt to Java key store:

1. Open a command console (cmd)
2. cd to C:\Program Files\Java\jdk1.8.0_131\bin
3. input

   keytool -import -trustcacerts -keystore "c:\Program Files\Java\jdk1.8.0_131\jre\lib\security\cacerts" -storepass changeit -noprompt -alias YOUR_ALIAS -file YOUR_CRT_FILE_LOCATION.crt

4. The screen should display Certificate was added to keystore if everything runs fine.

For the above command, YOUR_ALIAS can be anything that related to your cert you like, and YOUR_CRT_FILE_LOCATION.crt is the location of your crt file.
