摘要：There has been a tremendous enhancement in the field of cryptography, which tries to manipulate the plaintext so it becomes unreadable, less prone to hacker and crackers, and again obtain the plaintext back by manipulating this unreadable text and images in some way. In this regard, we have modified one secure algorithm Blowfish [1] which are secret ¨C key block cipher that enhance performance by modifying their function. Now in this paper we want show some results of performance analysis Blowfish and compare it with its modified version to prove that the modification does not violate security requirements. For this, we have considered different aspects of security namely, Encryp tion quality, Key sensitivity test and Statistical Analysis [4] on software implementation, we have implemented Shell and TCL- tk application to show the differences.
