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?
A. HMACSHA256
B. RNGCryptoServiceProvider
C. DES
D. Aes
Correct Answer: A
Explanation/Reference:
Explanation:
The .NET Framework provides the following classes that implement hashing algorithms:
HMACSHA1.
MACTripleDES.
MD5CryptoServiceProvider.
RIPEMD160.
SHA1Managed.
SHA256Managed.
SHA384Managed.
SHA512Managed.
HMAC variants of all of the Secure Hash Algorithm (SHA), Message Digest 5 (MD5), and RIPEMD-160 algorithms.
CryptoServiceProvider implementations (managed code wrappers) of all the SHA algorithms.
Cryptography Next Generation (CNG) implementations of all the MD5 and SHA algorithms.
