How Can I Automate .crt to pfx Conversion in Jenkins Pipelines Safely?

i am trying to understand how to automate .crt to pfx conversion using jenkins as a tool. as a user i want to create a workflow in jenkins that takes crt certificates and generates pfx files automatically within a pipeline.

.crt to pfx refers to the process of converting a certificate file in crt format into a pfx format which combines the certificate with its private key and allows it to be used in systems that require pfx files. this conversion also secures the private key with a password and makes it easier to manage certificates for applications that do not accept crt files directly. understanding how this conversion works helps me plan how to handle certificates efficiently in jenkins.

i want to know the best way to implement this in a jenkins pipeline. i am thinking about using scripts or commands in pipeline stages that can take a crt certificate and generate a pfx file automatically. i also want to make sure that the crt and pfx files are handled securely and that passwords are protected during the process.

i am considering that jenkins agents might run on different operating systems and i want a solution that works reliably across windows and linux without needing separate scripts for each. i am inspired by the idea of creating a pipeline where the .crt to pfx conversion happens automatically whenever a new certificate is added and the resulting pfx files are stored safely for further use.

i want to understand how to configure the pipeline so that the conversion is consistent secure and easy to manage. i would like guidance or examples on commands pipeline setup and secure file handling for automating .crt to pfx conversion in jenkins.
