* Zeroize several intermediate variables used to calculate the expected
value when verifying a MAC or AEAD tag. This hardens the library in
case the value leaks through a memory disclosure vulnerability. For
example, a memory disclosure vulnerability could have allowed a
man-in-the-middle to inject fake ciphertext into a DTLS connection.
