REST API connection to Qlik Sense on Windows from IICS

[sykvpk]

We are building a REST API connection from IICS (Informatica Intelligent Cloud Services) to Qlik Sense on Windows using this Qlik API.  We succeeded to make a REST API connection with curl, but not with REST V2 connector in IICS. They require certificate and key to be JKS format instead of pem files. Can we convert pem files to JKS format?

Another question is, according to IICS, Qlik API needs to support one-way or two ways authentication. Does Qlik API support them?
