Suggestions for the EasyEncrypt Application

Proposal

For the new Easy Encript 1.0 application, I have a few suggestions that should be made on the application that I believe will make the application better:

The below suggestions are when the user clicks on either the encrypt or decrypt button

1. A more detailed error message when an argument is missing or better said when the user of the application doesn't input or select everything required for the application to work instead of the now using error message of - Missing argument as shown in the image below,

I am suggesting that a more detailed error based on whats wrong for instance,

• when the user neither enters a messsage to be encrypted or decrypted should have the error - Please enter a text to be encrypted or decrypted (as shown in the image below)

• or when the user doesn't select an algorithm to be used, the error could be - Please select an algorithm you want to use.
  (as shown in the image below)

1. Lastly, I beleve the url of the logo of the Easy Encrypt is broken or wrong as highlight in the red box in the image below,I think the developer should look into

Benefits

The above will give the user more details when he/she encounters an error when using the application.
