The message text source is converted to base64 data and then encrypted with the ‘Default Cypher’ using the ‘Master Password’ as defined in the Preferences Window.
The ‘Default Cypher’ and ‘Master Password’ must be the same cypher / password used for the FooKey.
The message is then encrypted with the FooKey and saved in BASE64 format and loaded into ‘Log Control’ with each line prefixed with :

FooCryptMsg_1_153 where :
FooCryptMsg [ FooKey_Message Identification Prefix ]
