Question

How is the triple-DES key generated in Cryptex?

a.

By hashing the user-supplied password using the SHA algorithm and treating the resulting 160-bit hash as the key

b.

By encrypting the user-supplied password using the MD5 algorithm

c.

By using the user-supplied password as the key directly

d.

By randomly generating a key for each archive
