Techopedia Explains Fingerprint

When fingerprints are used for key authentication, systems can check these smaller data sets more easily in order to make sure that they are accessing the correct public key. Fingerprints are also more efficient for storage. Security certificate systems may manually perform key authentication to promote best security practices. Fingerprints are important in public-key cryptography and other modern types of digital security. They help to refine the ways that cryptography works in modern systems, where streamlining data sets is essential.
