Question

What is the easiest way to check Cryptex's password verification process?

a.

Start Cryptex in a debugger, feeding it with an incorrect password and try to catch the place in the code where Cryptex notifies the user that a bad password has been supplied.

b.

Analyze the source code of Cryptex to find out how it verifies the password.

c.

Launch Cryptex without a debugger and try to guess the correct password.

d.

None of the above.
