To configure HTTPS in Mule, a global HTTPS connector must be created and a keystore generated and referenced. A keystore is generated using the keytool command and contains the private key and certificates. The HTTPS connector is defined in Mule configuration with references to the keystore file. An inbound endpoint then uses the HTTPS connector to receive secure requests over HTTPS.

1. Configuration HTTPS

2. For Https configuration we should define a global connector and provide
keystore.
To create a global connector,click on global
Elements tab->Create->Connectors->HTTP/HTTPS.

4. To configure keystore. Genearate a keystore using the keytool. Go to
command prompt and type the command.
keytool -genkey -alias mydomain -keyalg RSA -keystore keystore.jks -
keysize 2048

7. Mule-Config looks like below.
