Hashing is used in databases for data … WebHow Does SHA1 Work? SHA1 works by taking a message of any length and processing it through a series of mathematical operations to produce a fixed-length output of 160 bits. The resulting hash is unique to the input message, meaning that any change to the input message will result in a completely different hash.
