Answer:
Explanation:
The correct answer is:
C) RSA
RSA stands for Rivest, Shamir, and Adleman, named after the three mathematicians who developed it in 1977. It is an encryption algorithm based on the practical difficulty of factoring the product of two large prime numbers.
RSA is a widely used asymmetric encryption algorithm that utilizes a pair of keys: a public key for encryption and a private key for decryption. The security of RSA relies on the fact that it is computationally difficult to factorize large numbers into their prime factors. This makes it difficult for an attacker to retrieve the private key from the public key.
Key sizes for RSA are typically from 1,024 to 4,096 bits, indicating the length of the key used in the encryption process. The longer the key, the more secure the encryption, but it also requires more computational resources.
In contrast to RSA, the other options mentioned are different cryptographic algorithms:
A) AES (Advanced Encryption Standard) is a symmetric encryption algorithm widely used for secure data transmission and storage.
B) SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that produces a 256-bit (32-byte) hash value.
D) MD5 (Message Digest Algorithm 5) is a cryptographic hash function that produces a 128-bit (16-byte) hash value. However, MD5 is considered to be outdated and insecure due to vulnerabilities discovered in the algorithm.
Therefore, the correct answer is C) RSA, as it aligns with the description provided in the question.
