WebMay 30, 2024 · What is a feature of a cryptographic hash function CCNA? Explanation: A cryptographic hash function should have the following properties:The input can be any length. The output has a fixed length. The hash value is relatively easy to compute for any given input. The hash is one way and not reversible. WebHashing is the transformation of a string of character s into a usually shorter fixed-length value or key that represents the original string. Hashing is used to index and retrieve items in a database because it is faster to find the item using the shorter hashed key than to find it using the original value. It is also used in many encryption ...
