CompTIA Security+ (SY0-501) — Question 9

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?

Answer options

• A. PFX
• B. PEM
• C. DER
• D. CER

Correct answer: B

Explanation

The correct answer is B, PEM, as it is specifically designed to store Base64 encoded data. PFX is typically used for packaging a private key with its associated certificate, while DER is a binary format not suitable for Base64 encoding. CER can be either binary or Base64, but PEM is the preferred format for this requirement.
