Which of the following is considered the most popular public key encryption algorithm?
RSA is the most popular public key encryption algorithm. RSA stands for Rivest-Shamir-Adleman, named after its inventors. It is widely used for securing sensitive data, particularly when being sent over an insecure network like the internet. AES (Advanced Encryption Standard) is also widely used but it is a symmetric key algorithm, not a public key algorithm. MD5 is a hashing algorithm, not an encryption algorithm. PGP (Pretty Good Privacy) is an encryption program that uses the RSA algorithm among others.
Answer should be A. RSA is the most popular algorithm: https://www.sciencedirect.com/topics/computer-science/public-key-algorithm PGP is an encryption program that makes use of the RSA algorithm: https://en.wikipedia.org/wiki/Pretty_Good_Privacy
Answer is A PGP is an encryption program that use RSA as encryption algorithm. The question is asking about "encryption algorithm", not "encryption program".
