The TLS … WebA cryptographic hash function is similar to a checksum. The main difference is that whereas a checksum is designed to detect accidental alterations in data, a cryptographic hash function is designed to detect deliberate alterations. When data is processed by a cryptographic hash function, a small string of bits, known as a hash, is generated. on shield
