Question

How do some dongle developers prevent the decrypted version of the code from being ripped from memory?

a.

By dividing the program into numerous small chunks that are each encrypted using a different key

b.

By using a trivial implementation of a dongle-based protection

c.

By designing the dongle so that it contains something that the program needs in order to run

d.

By providing an emulator program that emulates the dongle

Answer: (a).By dividing the program into numerous small chunks that are each encrypted using a different key Explanation:One solution employed by some dongle developers has been to divide the program into numerous small chunks that are each encrypted using a different key. During runtime only part of the program remains decrypted in memory at any given moment, and decryption requires different keys for different areas of the program.
