A security engineer is configuring a system that requires the X.509 certificate information to be pasted into a form field in Base64 encoded format to import it into the system.
Which of the following certificate formats should the engineer use to obtain the information in the required format?

X.509 is a standard format for digital certificates, which are used for secure communication over the internet. When a certificate is issued, it is typically saved in one of several common formats, including PFX, PEM, DER, and CER.
In this scenario, the security engineer needs to import the certificate information in Base64 encoded format into a form field. This means that the certificate needs to be converted into Base64 format, which is a way of encoding binary data as ASCII text.
Out of the given options, the format that is most commonly used for Base64 encoding is PEM. PEM stands for Privacy Enhanced Mail, and it is a widely used format for certificates and other cryptographic objects.
PEM certificates are encoded using Base64 and are enclosed between "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----" markers. To obtain the information in the required format, the security engineer should open the certificate file in a text editor, copy the contents between the markers, and paste it into the form field in Base64 encoded format.
The other formats listed as options, PFX, DER, and CER, are also used for certificates but are not commonly used for Base64 encoding.
PFX is a format used to store a private key with its associated certificate. It is often used for client certificates in Windows environments.
DER is a binary format that is used to store certificates and is often used in Java environments.
CER is a format used to store a single certificate, often used in Microsoft Windows environments.
In conclusion, out of the given options, the security engineer should use a PEM certificate to obtain the information in the required format.
