how to do the message encryption in mirth

Currently I am using the mirth 3.1.1, and i have update the mirth properties with configuration defined in the below link:



http://www.mirthcorp.com/community/w...+Configuration



However, the HL7 messages that are being exported to a folder are not being encrypted, I have also checked the encryption in summary tab, still no success.



is there any other way to call the encryption functions?

how can i use the mirth-cryto.jar file for the encryption?

is it possible to define encryption method while calling a java encryption function?

how can i get the encryption key?



Thank you for your help
