Question

How can you decipher the directory layout of Cryptex?

a.

By placing a breakpoint on the ReadFile API and tracing forward in the program.

b.

By restricting the ReadFile breakpoint to calls made on the archive file.

c.

By letting Cryptex run until it reaches the key-generation function and then stepping through the code until you reach interesting code areas that decipher the directory data structures.

d.

All of the above.
