WebA hash function should be deterministic: when it is invoked twice on pieces of data that should be considered equal (e.g., two strings containing the same characters), the function should produce the same value. This policy is crucial to the correctness of virtually all algorithms based on hashing. In the case of a hash table, the lookup ...

First, the initiator uses a hash function on the original message, and then concatenates this hash value (which for us will be 3 characters long) to form an augmented message; it then encrypts this augmented message using the receiver’s public key. It sends this encrypted message as usual. safe haven law definition
