Steps to generate self signed certificates using keytool

Filed under: Security — streethawkz @ 1:43 am

Below are the commands we need to run to generate self signed certificates :

  • keytool -genkey -alias cooldragon -keyalg RSA -keypass privatepassword -keystore identity.jks -storepass password ( create a key pair )








  • keytool -export -alias cooldragon -file root.cer -keystore identity.jks ( export the certificate from identity keystore into a file, say root.cer)








    • keytool -import -alias cooldragon -trustcacerts -file root.cer -keystore¬†trust.jks ( import the certificate you exported into trust.jks )








      • We can list the certificates present in the identity.jks using the following command :

        keytool -list -v -keystore  identity.jks -storepass password








        • Now lets view the file that was exported from the identity.jks ( i.e root.cer )

          keytool -printcert -file root.cer








          • To list the contents of trust.jks use the following command :

            keytool -list -v -keystore trust.jks -storepass password


            1. How about when using a certificate from verisign?

            3. Whoa! This blog looks exactly like my old one!
              It’s on a completely different subject but it has pretty much the same page layout and design. Great choice of colors!
