Based The Action Script2.0 Way Hash Security Components Design And Implementation

A website which is made wholly by FLASH is good at visual effects. It has strong ability to infect viewer, and this ability is much better than classic HTML website. It is deeply loved by people but, because of it's young, there is no component which can encrypt password for it. The truth that developers have no component to keep the website safe, limits the growth of Pure FLASH website.In this thesis, 6 kind of one way Hash Algorithm are realized on the developing platform of Action Script2.0, which is a kind of script language built in FLASH8, and the realizations are packaged up as a V2 component.The main results are as follows:Analysis the current situation of Pure FLASH website'safety; The basal data structure, constants and hash procedures used in the 6 kind of one way hash algorithms are explained in detail. How to realize the 6 kind of one way hash algorithms on the platform of Action Script 2.0 is introduced. How to package up the realizations as a V2 component is researched.
