Transporter MongoDB - ElasticSearch

Hi Guys !

I’m trying to implement a Transporter which take Data in a MongoDB Database and retrieve it in ElasticSearch.

For making that I’m using this Transporter : https://github.com/compose/transporter

I succeed to implement it in an ElasticSearch without SearchGuard in it but when I’m trying to put Data in ElasticSearch with Searchguard I got a certificate error. Fatal allert : bad_certificate.

Can i generate a specific certificate for this transporter, if yes How ?

I’m a little bit confusing with these certificates.

Thanks in advance for your response !
