What are certificate file formats supported on Windows? Are PKCS#12, PKCS#7, DER are PEM are valid certificate file formats on Windows?

Certificate import and export operations support four file formats on Windows systems. Choose the format that meets your specific requirements.

Personal Information Exchange (PKCS #12): The Personal Information Exchange format (PFX, also called PKCS #12) supports secure storage of certificates, private keys, and all certificates in a certification path. The PKCS #12 format is the only file format that can be used to export a certificate and its private key.

Cryptographic Message Syntax Standard (PKCS #7): The PKCS #7 format supports storage of certificates and all certificates in the certification path.

DER-encoded binary X.509: The Distinguished Encoding Rules (DER) format supports storage of a single certificate. This format does not support storage of the private key or certification path.

Base64-encoded X.509 (PEM): The Base64 (PEM) format supports storage of a single certificate. This format does not support storage of the private key or certification path.
