Image Enhancement And Contrast Enhancement in JAVA

In this article I’ll explain what is Image Enhancement? What is contrast enhancement? What’s the difference between the two? How to achieve one or the other or both? For simplicity, we’ll operate only on black and white images with gray scale of 0 – 255, and images will only be in pgm format. But if you understand the concept, then it can be expanded and applied on more complex formats as well e.g. RGB or CMYK etc. This article will probably be most useful for students and/or software developers who have to do some image processing work. However, other programmers can also try the code just for the sake of fun, because the results are so interesting and very easy to produce!

Implementation of RSA Cryptosystem in JAVA

In this article I’ll demonstrate how easy it is to implement the most popular asymmetric-key cryptosystem, RSA in Java language. RSA, named after its inventors Rivest, Shamir and Adleman, is basis of many modern encryption protocols e.g. SSL, PGP etc. The detailed explanation of how RSA works is beyond the scope of this article; nonetheless, you’ll find in this article practical implementation of RSA’s encryption and decryption algorithms. Moreover, you’ll also find, in its basic form, implementation of Optimal Asymmetric Encryption Padding (OAEP), which is an essential part of RSA (Thanks to Ojash Shrestha).
