Cryptographic hash function is used for creating the message digest. Message digest is a fixed length output of any variable length input. Hash functions are the tools which are used in digital signatures, digital time stamping and assuring the integrity of the messages. The absence of unintended changes or any alteration in some data between two updates of a data record is called data integrity. In this paper we have developed a new procedure for creating the message digest of any message. A comparison is done between the existing cryptographic hashing tool MD5 and our proposed optimized algorithm. In our algorithm the time lapsed to create a hash function from a plain text is less than the existing hashing tool MD5.
