how from *.crt get .p12 or .pem and key AND get jks file

I have latest anaplan certificate file .

To connect to anaplan i am using jks file.  My jks file is not latest hence I get below issue when I try to connect to anaplan,

Anaplan API: Certificate Authentication failed! (Feign: status 401 reading AnaplanAuthenticationAPI#authenticateCertificate(String,String); content:
{"status":"FAILURE_BAD_CREDENTIAL","statusMessage":"Authentication Failure. If you're unsuccessful after multiple attempts, your account may be locked. If you are using the Anaplan login page, click the 'Forgot Password' link. Otherwise, contact your Anaplan administrator or Anaplan Support."})


How can I get the latest jks file from the certificate file?
