Hash/Hashing

Hashing, or hash function, is a process that takes input data and generates a fixed-size output, which is a unique representation of the original data. This output is usually a small piece of data known as a hash code or message digest. Hashing is commonly used in computer science and cryptography to securely store and retrieve data, as well as to quickly search for and compare data. Hashing algorithms use complex mathematical formulas to convert the input data into a fixed-size output, and the same input will always generate the same output. Hashing is an important technique for protecting data integrity and minimizing the amount of storage space required for large amounts of data.
