The output is named hash or message digest, and is designed to protect the integrity of any kind of data, such as a file, media, or text. Only one message digest is assigned to protect a specific input or sensitive information. A small change made to the input data results in a drastic difference in the result, which makes it almost impossible to predict the data either in- motion or at rest. There are various ways to produce the hash or the message digest. In the world of cryptocurrency, and Bitcoin being a popular example, the SHA-265 algorithm is used to produce a fixed-length ...
