WebHashing is an algorithm that calculates a fixed-size bit string value from a file. A file basically contains blocks of data. Hashing transforms this data into a far shorter fixed-length value or key which represents the original string. The hash value can be considered the distilled summary of everything within that file. WebHash (H1) over k characters (c1..ck) could be computed as follows: H1= c1*a^k-1 + c2*a^k-2+c3*a^k-3+…+ck*a^0. where a is a constant. and c1…ck are input characters. Lets …
