Cryptographic Hash Function
| A cryptographic hash function is an algorithm that produces a fixed-size hash value from a variable-size transaction input. A hash value is a numerical value that is used to identify a piece of data. Hash values are typically used to verify the integrity of data. A cryptographic hash function is a mathematical function that is used to map data of arbitrary size to data of fixed size. The data that is mapped is called the message, and the output of the hash function is called the message digest. |
