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.
However, the attack cannot be extended to the hash algorithm, due to the non-symmetric IV, the addition of the block counter and the existence of the finalization rounds. [ 4 ] [ 5 ] Another distinguisher was presented, based on the observation that multiplication by three preserves the difference in the most significant bit with probability one.
