And the (bad) thing about them is that they acceptĬertificate files that are encoded and formatted in a certain manner. This type of file usually contains data in PKCS#12 format (e.g., with PFX files generated in IIS).ĭifferent Servers Require Different Formats & p12 - PKCS#12 files may contain certificate(s) (public) and private keys (password protected). p7c - PKCS#7 SignedData structure without data, just certificate(s) or CRL(s). der - Although usually in binary DER form, Base64-encoded certificates are also common (see. pem - This is a (Privacy-enhanced Electronic Mail) Base64 encoded DER certificate, enclosed between “-–BEGIN CERTIFICATE-–” and “-–END CERTIFICATE-–“ These digital certificates haveĭifferent filename extensions and formats.
