Install the root and intermediate certificates

2. Type in the following command:

keytool -import -v -trustcacerts -alias root -file root.crt where root.crt is the root certificate.

3. Install the two intermediate certificates:

keytool -import -v -trustcacerts -alias inter1 -file priminter.crt where priminter.crt is the primary intermediate certificate.

keytool -import -v -trustcacerts -alias inter2 -file secinter.crt where secinter.crt is the primary intermediate certificate.

Install your Code Signing Certificate and Sign your JAR files

1. Launch a command prompt and go to your JDK directory.

2. Type in the following command to install your Code Signing certificate:

keytool -import -alias MyCert -file YourCert.cer where YourCert.cer is your Code Signing certificate.

3. Sign your files by using this command-line:

jarsigner c:\yourfile.jar MyCert where yourfile.jar is the file you want to sign.

You can verify the signature with the following command-line:

jarsigner -verify -verbose -certs c:\yourfile.jar
