Question
a.
Because it is impossible to obtain the original data from the MD5 hash value stored in the header.
b.
Because someone would be able to covert the MD5 hash value to an equivalent SHA hash value.
c.
Because the plaintext password might not be available at the time of verification.
d.
Because it is virtually guaranteed to be mathematically impossible to obtain the original data from the SHA hash value.
