AES Encryption 5: Expand Keys and Encryption Flow
In this vid we'll complete the encryption side of our implementation of AES. I've decided not to go though decryption, which is much the same type of logic in reverse, and with the opposite look-up tables. If you actually have to include AES in your programs, use assembly or AES intrinsics. Our implementation is not secure, and it's very slow. Modern CPU's have an instruction set called the AES Instruction Set, which makes this whole task a lot easier, and a lot faster. The babies you can hear at point are my sweet little nieces. I live with my bro and his gf. They've just had twins. They sound like they're being attacked by an elephant, but they are just hungry. They quieten down when their ma feeds them. I hope this vid series was helpful for folks studying the algorithm. There's very few examples of exactly how to code this thing. Anywho, I really wanted to make a good go of it. Well here it is! Now we can look at something completely different! Well probably not that different...?

Obfuscated C programs: Introduction
If you program long enough, eventually you will run into a programming art category called "obfuscated code" or “code golf”. You can find these especially at IOCCC. In this video I introduce the concept and the basic ideas behind such design. More information below (click "Show more"). I realize the category is "obfuscated code", not "small code", but often trying to compress your code into the smallest size will also effectively obfuscate its function. I also realize that some of the individual changes I did in the video did actually _not_ result in smaller program code size, but the opposite. But the end result is still the shortest I could manage, if you remove the "int", the "return", and the space after "include". Actual obfuscation techniques include using small and meaningless variable names, using unusual syntax constructs, redefining reserved words, adding code that appears to do one thing but does something else (or nothing at all), creating a complex machinery (such as an interpreter) to do a different task, encryption, and so on.

C++ program on Cryptography
The myth of C/C++ is a programming language that could be said, the “authorized” programming language of cryptography, since it has converted the normal variety of standard regulatory institutes for example FIPS, NIST, plus others like freelance services. Greatest performance is still held through the C/C++, plus why few in number? One cause for this programming language difficult to learn than derivatives. This is a C++ Program toward implement substitution technique. In cryptography, a transposition cipher is a technique of encryption through which the places held through units of plaintext (which are usually characters or collections of characters) are shifted as said by a steady system, so as to the ciphertext creates a permutation of the plain text. That is, the order of the elements is changed (the plain text is reordered). Mathematically a bijective role is used in the characters’ places to encrypt and a converse function to decrypt.

AES Encryption 2: AddRoundKey, SubBytes and ShiftRows
In this vid we'll fill out the bodies to three of the steps in AES. These three steps are AddRoundKey, SubBytes and ShiftRows. The remaining steps to AES are rather fiddly, MixColumns and ExpandKey, so we'll look at those separately. I've also taken the opportunity to introduce Galois fields for the AddRoundKey section. AddRoundKey is really just a matter of performing XOR, but it helps to understand Galois fields before we come to the MixColumns step.

This is a short vid which shows the code for the matrix multiplication for the MixColumns step. I initially intended to make this vid and the previous AES one around the same length, but we actually covered almost everything in the previous vid! Mix Columns Wikipedia Page: https://en.wikipedia.org/wiki/Rijndael_mix_columns Code for dot products: tmp[0] = (unsigned char)(mul2[state[0]] ^ mul3[state[1]] ^ state[2] ^ state[3]); tmp[1] = (unsigned char)(state[0] ^ mul2[state[1]] ^ mul3[state[2]] ^ state[3]); tmp[2] = (unsigned char)(state[0] ^ state[1] ^ mul2[state[2]] ^ mul3[state[3]]); tmp[3] = (unsigned char)(mul3[state[0]] ^ state[1] ^ state[2] ^ mul2[state[3]]); tmp[4] = (unsigned char)(mul2[state[4]] ^ mul3[state[5]] ^ state[6] ^ state[7]); tmp[5] = (unsigned char)(state[4] ^ mul2[state[5]] ^ mul3[state[6]] ^ state[7]); tmp[6] = (unsigned char)(state[4] ^ state[5] ^ mul2[state[6]] ^ mul3[state[7]]); tmp[7] = (unsigned char)(mul3[state[4]] ^ state[5] ^ state[6] ^ mul2[state[7]]); tmp[8] = (unsigned char)(mul2[state[8]] ^ mul3[state[9]] ^ state[10] ^ state[11]); tmp[9] = (unsigned char)(state[8] ^ mul2[state[9]] ^ mul3[state[10]] ^ state[11]); tmp[10] = (unsigned char)(state[8] ^ state[9] ^ mul2[state[10]] ^ mul3[state[11]]); tmp[11] = (unsigned char)(mul3[state[8]] ^ state[9] ^ state[10] ^ mul2[state[11]]); tmp[12] = (unsigned char)(mul2[state[12]] ^ mul3[state[13]] ^ state[14] ^ state[15]); tmp[13] = (unsigned char)(state[12] ^ mul2[state[13]] ^ mul3[state[14]] ^ state[15]); tmp[14] = (unsigned char)(state[12] ^ state[13] ^ mul2[state[14]] ^ mul3[state[15]]); tmp[15] = (unsigned char)(mul3[state[12]] ^ state[13] ^ state[14] ^ mul2[state[15]]); Music Channel: Sober: https://youtu.be/Y2LCg3cGu7U Gold Digger: https://youtu.be/wAoXB8tg0co Become a patron and support What's a Creel programming vids on Patreon: www.patreon.com/whatsacreel FaceBook: www.facebook.com/pages/WhatsaCreel/167732956665435
