I have started working on Pre-Login but I am facing problem on device certificate. I have been given device certificate in .cer format by my IT Team along with password but looks the CMA portal accepts only in .pem format. Can someone help me in this.
If your .cer file is text based it is already in PEM format and you should be able to just rename the file extension to .pem and upload it.
I tried renaming the .cer file with .pem but it is giving same error "Wrong file type, only PEM files are supported."
Right, but did you check the contents of the certificate file? Is it a base64 encoded text file or a binary file?
