CompTIA Security+ (SY0-501) — Question 910

A systems administrator just issued the ssh-keygen `"t rsa command on a Linux terminal. Which of the following BEST describes what the rsa portion of the command represents?

Answer options

• A. A key generation algorithm
• B. A hashing algorithm
• C. A public key infrastructure type
• D. A certificate authority type

Correct answer: A

Explanation

The 'rsa' portion of the command specifies the type of key generation algorithm being used, which is RSA (Rivest-Shamir-Adleman). The other options, including hashing algorithms, public key infrastructure types, and certificate authorities, do not accurately represent the function of the rsa parameter in this context.
