Way to store certificate and key securely without using folder

Sangavi_M

Hi !

Our plugin needs certificate and key(types of which is not supported as dataiku dataset) for authentication purpose to fetch the data . I'm giving these by creating a folder in a secure location(using project connection, macros) and attaching it to plugin as input and specifying in UI the file names it should look for inside the folder 

Is there any other way i can store the certificate and key in the project securely without using a folder, and just directly give the path to the where its stored in certificate and key input fields in plugin UI and use those paths in our plugin to access the input files?
