Quartz integration does not work with bus encryption

Hello!

Working on a project with MT 3 and the quartz scheduler, we ran into an issue using the quartz integration piece with encryption.

after looking through the repoI think it’s being thrown here line 55? after looking at the content-type before publish is “application/vnd.masstransit+aes”

Any new info on this? Is there a proper workaround? We are sending sensitive information over the bus and this actually is stoping us from using encryption. Thank you

So yeah, getting the scheduler to work with encrypted messages is going to be complicated, since encrypted messages are binary and we are using a string column in SQL to store the message. There is also some JSON token manipulation happening under the hood to include the original data in the message.

I’m not saying it’s impossible, but I spent an hour or two trying to get it to work and realized that the binary encrypted body is a hard nut to crack.
