Use keytool to generate keys in java

1. keytool -genkey -alias weblogic -keyalg RSA -keystore server.keystore
2. keytool -selfcert -export -alias weblogic -storepass changeit -file server.cer -keystore server.keystore
3. keytool -genkey -alias client -keyalg RSA -keystore client.keystore
4. keytool -selfcert -export -alias client -storepass changeit -file client.cer -keystore client.keystore
5. keytool -import -v -trustcacerts -alias weblogic -file server.cer -keystore client.keystore -keypass changeit -storepass changeit
6. keytool -keystore \jre\lib\security\cacerts -storepass changeit -file client.cer -import -alias client -trustcacerts

Here, i have created server.cer and client.cer certificates. Password used is "changeit".
