A C Yes, because this would allow the hash to contribute to error detection and correction operations. B O In a limited way, they are reversible, because the hash acts as a pointer or key into database and file management systems where the plaintext comes from. C D O No, because a hash is a many-to-one function and thus must have a collision detection and avoidance mechanism as part of its implementation; being reversible would negate this. O No, because this would allow the plaintext to be decrypted from the hash, rendering message digests and digital signatures unworkable
