Hi,


Sometime you may require a PFX file ( SSL ) for Windows Server IIS. Go to below link and select options 


Form ===> Standard PEM 


To ===> PFX / PKCS#12


Provide all SSL files ( CRT , PRIVATE KEY & Intermediate Certificates ) , it will convert to PFX . Now your PFX file will be have all required SSL. Note PFX password which is required to install PFX.
