Implementation of Security Package for Data Integrity with Various Hash Algorithms

This paper deals with the implementation of security package of Hash algorithms which can be chosen by the user for their desired level of security. The concept of encryption and decryption of message is not enough for the security of data’s in current communication. Hence the concept of Message authentication is developed. One type of authentication is by Hash algorithm. Hash algorithm creates the miniature of the message. Hash algorithm takes an input message of length less than 264 (varies with the type of algorithm) and gives the output in fixed length. For the application point of view we need the comparison of their performance. Hence this paper involves the following categories. a Implementation of MD5 algorithm b Implementation of SHA algorithm c Implementation of RIPEMD algorithm d Comparison of algorithms with respect to their a. Speed b. Security e Implementation of software package.
