5. FooKey Message Decrypt

Menu Select -> Decrypt Message

FooCrypt will then decrypt the Message Source for the number of cycles contained in the FooKey and display the decrypted message in the Log Control as a StdOutLog and in AllStdOutLog

6. Technical Specifications Of FooKey_Message

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 ]
Line Number
Total Number Of Lines

The last line of a FooKey_Message contains an MD5 checksum of the entire message which is used during decryption validation
