Claim 5:
6. A hash algorithm method implemented by a hash algorithm circuit, comprising:
providing the hash algorithm circuit, wherein the hash algorithm circuit comprises an input circuit unit, at least one hash circuit unit, acid an output circuit unit electrically coupled in sequence;
using the input circuit unit o receive data to be processed;
using the at least one hash circuit unit to form the data to be processed, passing through the hash circuit unit, into a target data according to a preset hash algorithm, wherein a data length of the data to be processed is greater than a data length of the target data; and
outputting the target data by the output circuit unit, wherein
the hash algorithm circuit comprises a first hash circuit unit electrically coupled to the input circuit unit and a second hash circuit unit electrically connected to the first hash circuit unit;
the hash algorithm method further comprises:
using the first hash circuit unit to form the data to be processed into an intermediate data according to a first preset hash algorithm, the data length of the data to be processed is greater than a data length of the intermediate data, and
using the second hash circuit unit to form the intermediate data into the target data according to a second preset hash algorithm, wherein the data length of the intermediate data is greater than the data length of the target data;
wherein
the data to be processed is divided into n sequences, and
the hash algorithm method further comprises:
using the first hash circuit unit to form, through its circuit structure, the n sequences into the intermediate data having k sequences according to the first preset hash algorithm, where n and k are both natural numbers, and n>k; and
using the second hash circuit unit to form, through its circuit structure, the k sequences into the target data having u sequences according to the second preset hash algorithm, where u is a natural number, and k>u.
