WebA cryptographic hash function aims to guarantee a number of security properties. Most importantly that it's hard to find collisions or pre-images and that the output appears random. (There are a few more properties, and "hard" has well defined bounds in this context, but that's not important here.) WebA cryptographic algorithm is the mathematical equation used to scramble the plain text and make it unreadable. They are used for data encryption, authentication and digital signatures. There are three types of cryptography: Symmetric-key cryptography - Both sender and receiver share a single key and the sender uses this key to encrypt plaintext.
