Hello people,
It’s been a while since I have last posted an article. I decided to write an article about the Advanced Encryption Standard. I will explain certain concepts regarding AES and how it basically works. I will provide step by step C code, to make it even easier to understand. You can find the full source code at the end of this article. Actually many websites around the net provide source code for AES. This one is supposed to be easy to understand ;)

Hello,
This is my second post in this blog.
Today I will explain the RC4 algorithm, and will also provide my implementation.
RC4 is a stream cipher created by Ronald Rivest in 1987.
Quoted from wikipedia:
RC4 was initially a trade secret, but in September 1994 a description of it was anonymously posted to the Cypherpunks mailing list[3]. It was soon posted on the sci.crypt newsgroup, and from there to many sites on the Internet. The leaked code was confirmed to be genuine as its output was found to match that of proprietary software using licensed RC4. Because the algorithm is known, it is no longer a trade secret.
