PEM (originally ?Privacy Enhanced Mail?) is the most common format for X. 509 certificates, CSRs, and cryptographic keys. A PEM file is a text file containing one or more items in Base64 ASCII encoding, each with plain-text headers and footers (e.g. -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- ).

Installing the X509 Certificates is a quite simple one-step process, once you have the PKCS12 file (. p12) and its encryption password (sent to the representatives). On most systems, it can be installed as simple as double-clicking the downloaded file and following your OS wizard instructions.

Submit the certificate request: You must submit the certificate request to a trusted Certificate Authority (CA) that can verify your identity and issue a valid X. 509 certificate. You can choose a public CA like Let's Encrypt, or a private CA for your organization.

The process of getting an X. 509 certificate involves generating a key pair, creating a certificate request, submitting the request to a trusted CA, verifying your identity, receiving the X. 509 certificate, and installing it on your server or device.

The x509 utility can be used to sign certificates and requests: it can thus behave like a "mini CA". this option causes the input file to be self signed using the supplied private key.

A certificate authority (CA), subordinate CA, or registration authority issues X. 509 certificates. The certificates contain the public key of the certificate subject. They don't contain the subject's private key, which must be stored securely.
