A software developer is working on a piece of code required by a new software package. The code should use a protocol to verify the validity of a remote identity. Which of the following should the developer implement in the code?
A software developer is working on a piece of code required by a new software package. The code should use a protocol to verify the validity of a remote identity. Which of the following should the developer implement in the code?
The developer should implement OCSP (Online Certificate Status Protocol). OCSP is a protocol used to check the revocation status of an X.509 digital certificate, providing real-time responses from the Certificate Authority (CA) about the validity of a certificate. This makes it suitable for verifying the validity of a remote identity. RSA is a cryptographic algorithm used for secure data transmission, not a protocol. HSTS (HTTP Strict Transport Security) is a security policy mechanism for enforcing HTTPS, while CRL (Certificate Revocation List) is a less efficient method of checking certificate revocation.
Online Certificate Status Protocol (OCSP) Another means of providing up to date information regarding the status of a certificate is to check the certificate’s status on an Online Certificate Status Protocol (OCSP) server, referred to as an OCSP responder. Rather than return a whole CRL, this just communicates the status of the requested certificate. Details of the OCSP responder service should be published in the certificate.
Validity key
B. as RSA is encryption algorithm.
RSA is a cryptographic algorithm used for secure data transmission. While it’s important for encryption and digital signatures, it is not a protocol for verifying the validity of a remote identity in terms of certificate status. OCSP is a protocol used to check the revocation status of an X.509 digital certificate. It provides real-time responses from the Certificate Authority (CA) about the validity of a certificate, making it suitable for verifying the validity of a remote identity. HSTS is a security policy mechanism that helps protect websites against protocol downgrade attacks and cookie hijacking by enforcing the use of HTTPS. CRL is a list of revoked certificates published by a Certificate Authority. While it also serves the purpose of checking certificate revocation, it is less efficient than OCSP because it requires the client to download the entire list and check against it, which can be cumbersome and not real-time.
According to Google..."What is OCSP? The Online Certificate Status Protocol (OCSP) is an alternative to the certificate revocation list (CRL) and is used to check whether a digital certificate is valid or if it has been revoked." So that means OCSP and CRL are the same and NOT the right answer. I'm going with A RSA.
It's 100% A "RSA can also be used for creating digital signatures, ensuring data integrity and authentication. By signing a message with their private key, the sender can verify their identity, and the recipient can verify the integrity of the message using the sender's public key."
It's 100% not A. RSA is not a protocol. SMH
