Prompt MACing uses a key that depends on how the form/prompt authentication option is 
set. If set to: 

 

Terminal based, Prompt MACing will use terminal based clear text key if the form is 
set to clear text entry. It will use the terminal-based security text key if the form is 
set to secure text entry.  

 

Application based, Prompt MACing will use application based clear text key if the 
form is set to clear text entry. It will use the application-based security text key if 
the form is set to security text entry. 

Prompt MACing will be used to authenticate the prompts during the data entry process and 
the load font process.
