Often, an additional hash of the hash list itself (a top hash, also called root hash or master hash) is used.Before downloading a file on a p2p network, in most cases the top hash is acquired from a trusted source, for instance a friend or a web site that is known to have good recommendations of files to download.

A hash table uses a hash function to compute an index, also called a hash code, into an array of buckets or slots, from which the desired value can be found. During lookup, the key is hashed and the resulting hash indicates where the corresponding value is stored. A map implemented by a hash table is called a hash map.
The following tables compare general and technical information for a number of cryptographic hash functions. See the individual functions' articles for further information. This article is not all-inclusive or necessarily up-to-date. An overview of hash function security/cryptanalysis can be found at hash function security summary.
Hash function, an encoding of data into a small, fixed size; used in hash tables and cryptography Hash table, a data structure using hash functions; Cryptographic hash function, a hash function used to authenticate message integrity; URI fragment, in computer hypertext, a string of characters that refers to a subordinate resource
