WebMar 1, 2024 · In hashing there is a hash function that maps keys to some values. But these hashing function may lead to collision that is two or more keys are mapped to same value. Chain hashing avoids collision. The idea is to make each cell of hash table point to a linked list of records that have same hash function value. WebApr 13, 2024 · The signature is created from the encoded header, encoded payload, a secret (or private key, read further) and a cryptographic algorithm.
