Montags and Clarisse's realtionship is weird. If she had not died I think they would have become a lot closer throughout the book. Clarisse seemed to bring out a different side of Montag. They way she would ask him questions and make things for him.
JKS stands for Java KeyStore. It is a repository of certificates (signed public keys) and [private] keys. You can export a certificate stored in a JKS file into a certificate file. You can use the keytool utility found in Java distributions to maintain your JKS trust and key repositories.
If your private key has a password, It would promote to enter the password of private key. You need to define a password for PKCS 12 file as well. Step 2. Created PKCS 12 file has been given as the source keystore and new file name (wso2carbon.jks) has been given as the destination keystore.
