Cryptographic hash code
WebA message digest(also known as a cryptographic checksumor cryptographic hashcode) is nothing more than a number - a special number that is effectively a hashcode produced by a function that is very difficult to reverse. A digital signatureis (most often) a message digest encrypted with someone's private key to certify the contents. This Web(t/f) Hash functions can be used for intrusion and virus detection. t (t/f) The cryptographic hash function is not a versatile cryptographic algorithm. f (t/f) It is possible to use a hash function but no encryption for message authentication. t (t/f) Hash functions are commonly used to create a one-way password file. t
