A one-way hash function starts with a group of characters, called a key, which you then map onto a hash, or hash value, which is a certain length. Modern hashes are 128 bits or more; however, the hash value will be shorter than the original string of characters. The hash value is sometimes called a message digest. can a bob stroller go on the beachWebNorthwestern University; Electrical Eng./Computer Science Dept. 2145 Sheridan Rd.
