Installing RTE’s applications certificates

RTE’s applications certificates will be installed by "Cross certification" when you received your first signed-encrypted email from the application.

Note:

The "Cross certification" is a process which makes a user able to install the certificate of another entity while he receives a message form that entity. Messages sent to that specific entity will be encrypted with that "Cross certification".
