Which of the following is a valid key length for the TripleDES symmetric cryptography class?

The correct answer is D. 128. TripleDES is used to support key lengths from 128 bits to 192 bits in increments of 64 bits. The TripleDES class exposes the base class for Triple Data Encryption Standard algorithms from which all TripleDES implementations must inherit. The TripleDES class makes use of three…

Explanation

TripleDES is used to support key lengths from 128 bits to 192 bits in increments of 64 bits. The TripleDES class exposes the base class for Triple Data Encryption Standard algorithms from which all TripleDES implementations must inherit. The TripleDES class makes use of three successive iterations of the DES algorithm. It can use either two or three 56-bit keys.
