Usage: 
 - Step 1: 
    Add data to 3 keys in file create-keystore.conf, this is the installation file to run create-keystore.sh. 
        NAME_FILE : name of file key store
        NAME_ALIAS : name if Alias
        PASSWORD : password of keyPassword and storePassword
- Step 2:
    Run script with command: 
        bash create-keystore.sh
- Step 3: Enter info of key

Note: In the final step, a few cases will ask:
        Enter key password for <mstoreapp>
        (RETURN if same as keystore password):
Press "Enter" to finish.
