The Design and Implementation of Passwords Management System Based on Blowfish Cryptographic Algorithm

In modern society, especially on the Internet, you might have found you are having more and more usernames or IDs and passwords, which contains your private information. There are too many for you to remember and it is unsafe to write them down on you notebook. To solve this problem, this paper made a design and implementation of Passwords Management System (PMS), by which you can manage your usernames and passwords efficiently. It was made based on Blowfish Algorithm, which is a symmetric block cipher and designed by Bruce Schneier in 1993. Firstly, the paper made an introduction of the theory and advantages of Blowfish Encryption Algorithm, described some important details of its encryption process, and then designed and implemented the PMS.
