+[InstallCert](https://www.netradius.com/)
+==============================================
+
+The goal of this project is to create a Jar file InstallCert.jar which downloads certificate chain from a remote host
+and adds the certificates to a local keystore.
+
+## Where do I download InstallCert?
+You can clone the repository in a location where there is enough free space to hold the repository source code.
+
+In order to Clone this repository, please use the following command at a location where you intend to download

+
+
+## How do I build InstallCert?

+file in the project and then run the following command
+
+./mvnw clean package
+
+## How do I run InstallCert?
+In order to run the jar, you need to open a command prompt, navigate to the same directory as the top level pom.xml 
+file in the project and then run the following command
+
+java -jar ./target/install-cert-X.X.X-SNAPSHOT.jar -h HOST_NAME_OR_IP –k PATH_TO_JAVA_TRUSTSTORE –s 
+PASSWORD_FOR_TRUSTSTORE -p PORT_TO_CONNECT
+
+
+where following are the options you may need to add while running above command
+
+-b,--backup                    backup keystore before save
+-h,--host <host>               host to connect to
+-H,--help                      print this menu
+-k,--keystore <keystore>       keystore to add to (default is the JVM
+                                cacerts file))
+-n,--noprompt                  do not prompt to save
+-p,--port <port>               port to connect to (default 443)
+-s,--passphrase <passphrase>   passphrase for key store (default
+                                changeit)
+
+Example
+
+java -jar ./target/install-cert-1.0.0-SNAPSHOT.jar -h google.com -k $(/usr/libexec/java_home)
+/jre/lib/security/cacerts -s changeit -p 443
+
+Sample Output:
+install-cert abhi$ java -jar ./target/install-cert-1.0.0-SNAPSHOT.jar -h google.com -k 
+/Test/cacerts -s changeit -p 443
+opening connect to google.com:443
