The output of hashing is popularly known as a digest.
Hashing is the process of taking an input (such as a message or data file) and producing a fixed-length string of characters, which is the digest or hash. This hash is unique to the input data, and even a small change in the input data will result in a completely different hash. Hashing is widely used in cryptography and blockchain technology to ensure the integrity and authenticity of data.
