i have been using n8n for automating tasks and sometimes i need to work with SSL certificates i usually have crt files that must be converted into pfx format to be used in certain nodes i inspired from the idea of crt to pfx conversion positively because it seems like a simple step that could make workflows much smoother a crt to pfx conversion is the process of taking a certificate file in crt format which typically contains the public certificate and optionally the private key and combining it into a single pfx file which can then be used in systems that require a pfx container for authentication or encryption this process ensures that the certificate and private key are packaged together in a format that can be easily imported and recognized by applications i want to understand how this conversion can fit naturally into n8n workflows so that i do not have to rely on external tools or manual steps i am curious if there is a way to automate this process within n8n and manage the certificates safely while passing them between nodes i usually save them temporarily in environment variables or encrypted credentials and i wonder if anyone has methods to make this smoother and more reliable
