Which types of SSL certificates are the most commonly used?

• A. PEM or PEX
• B. CRT or DER
• C. PFX or PKCS
• D. X.509 or SSL

Answer: (A)

The most commonly used types of SSL certificates are X.509 or SSL. This is because X.509 is the standard that defines the format for public key certificates, which are essential for establishing secure connections over the internet. SSL, which stands for Secure Sockets Layer, is a protocol that uses these certificates to secure data transmission. X.509 certificates play a crucial role in authentication and encryption processes by binding a public key to the identity of an individual, organization, or device. This is fundamental for creating a secure channel, such as HTTPS, which is essential for secure online communications. Other options listed do not represent common types of SSL certificates or relate to the broader context of SSL standards and implementations.
