WebJul 26, 2024 · A cryptographic hash function (CHF) is an algorithm that can be run on data such as an individual file or a password to produce a value called a checksum . The main … WebCryptographic Hash Function The hash function is another secure way of encryption. Hashing is the act of generating a number from a string of text. The hash is substantially smaller than the text itself, and is generated by a formula in such a way that it is extremely unlikely that some other text will produce the same hash value.

WebA cryptographic algorithm is the mathematical equation used to scramble the plain text and make it unreadable. They are used for data encryption, authentication and digital signatures. There are three types of cryptography: Symmetric-key cryptography - Both sender and receiver share a single key and the sender uses this key to encrypt plaintext. WebMar 14, 2024 · Hashing is similar to encryption in that it scrambles the input data into a randomized or near-randomized output data. Hashing differs significantly from encryption, however, in that it is a one-way process. There is no easy way to unscramble the data, interpret the output, or reverse-engineer the input.
