Text And Image Encryption Decryption Using Symmetric Key Algorithms On Different Platforms

In today’s era we need to secure information stored in our computer or transmitted through internet against various attacks. Cryptography is an important tool to protect our information against malicious attacks of today. There are several cryptographic algorithms available to secured our information. Each algorithm has its own strong and weak points. This paper provides an analysis and comparison of some symmetric key cryptographic ciphers (DES, Triple DES, AES, Blowfish) on the basis of encryption and decryption time with different sizes text files and also image files on two different operating system using Java as the programming language.
