A One-Way Hashing Algorithm with Variable Length of Output

A One-way hashing algorithm with variable length of output is presented in the paper. The algorithm compresses a message of arbitrary length into a digest of 128,160,192,224,256 bits. The advantages of the algorithm are simple in design,fast in speed,very efficient and particularly suited for 32-bit computer which predominates the current workstation market. The algorithm is prior to SHA in secure.it can thwart not only the known attacks,but also future unknown attacks. The specifications, design rationale and security analysis are given in the paper. In addition,the compared results to other algorithms are listed at the end of the paper.
