The message text source is converted to base64 data and then encrypted with the ‘Default Cypher’ using the ‘FooKey_Password’ as defined in the Preferences Window.
The ‘Default Cypher’ and ‘FooKey_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 ]

The last line of a FooKey_Message contains an SHA256 checksum of the entire message which is used during decryption validation
