Programming in C# — Question 157

You are developing an application that will transmit large amounts of data between a client computer and a server.
You need to ensure the validity of the data by using a cryptographic hashing algorithm.
Which algorithm should you use?

Answer options

• A. DES
• B. HMACSHA512
• C. RNGCryptoServiceProvider
• D. ECDsa

Correct answer: B

Explanation

HMACSHA512 is a hashing algorithm that combines a cryptographic hash function with a secret key, making it suitable for data integrity verification. DES is a symmetric-key algorithm primarily used for encryption, while RNGCryptoServiceProvider is for generating random numbers, and ECDsa is used for digital signatures rather than hashing.
