Question

What does the use of the Windows Crypto API by Cryptex indicate?

a.

It indicates that it uses built-in implementation of the encryption algorithm.

b.

It indicates that it uses generic cryptographic library that provides support for installable cryptographic service providers (CSPs).

c.

It indicates that it does not support a wide range of symmetric and asymmetric cryptographic algorithms such as DES, RSA, and AES.

d.

It indicates that it is going to be quite difficult to determine which encryption algorithms the program employs and how it produces the encryption keys.

Answer: (b).It indicates that it uses generic cryptographic library that provides support for installable cryptographic service providers (CSPs). Explanation:The use of the Windows Crypto API by Cryptex indicates that it uses a generic cryptographic library that provides support for installable cryptographic service providers (CSPs) and can be used for encrypting and decrypting data using a variety of cryptographic algorithms. Microsoft provides several CSPs that support a wide range of symmetric and asymmetric cryptographic algorithms such as DES, RSA, and AES.
