98-372 · Question #108
Which of the following are valid key lengths for the RijndaelManaged symmetric cryptography class? Each correct answer represents a complete solution. Choose all that apply.
The correct answer is C. 256 D. 128. The RijndaelManaged class can use key lengths of 128 through 256 bits, in 32-bit increments. The RijndaelManaged class is used to access the managed version of the Rijndael algorithm. The RijndaelManaged class cannot be inherited. In other words, this algorithm supports key…

Explanation
The RijndaelManaged class can use key lengths of 128 through 256 bits, in 32-bit increments. The RijndaelManaged class is used to access the managed version of the Rijndael algorithm. The RijndaelManaged class cannot be inherited. In other words, this algorithm supports key lengths of 128, 192, or 256 bits. Answer: A and B are incorrect. 512 and 1024 bits are too large for the RijndaelManaged class.
