Question

Why doesn't Cryptex store the SHA result directly into the file header?

a.

Because it is impossible to extract the original plaintext password from the SHA hash value

b.

Because it would make it incredibly easy to decrypt Cryptex archives

c.

Because someone would be able to covert the MD5 hash value to an equivalent SHA hash value and effectively obtain the decryption key

d.

Because the SHA hash is directly used as the encryption key

Posted under Reverse Engineering

Answer: (b).Because it would make it incredibly easy to decrypt Cryptex archives Explanation:Storing the SHA hash in the file header would make it incredibly easy to decrypt Cryptex archives.
