Today we'll begin looking at the most widely used data encryption in the world, the AES Encryption Algorithm! It's a symmetric key encryption algorithm. It scrambles data so you can securely store sensitive information on drives or USB's or transfer data over a network. Over the course of the next videos in this series, we'll drill down and examine exactly how the algorithm works. I hope to present it in such a way that you could encrypt data with a pen and paper!

Supplement to the cryptocurrency video: How hard is it to find a 256-bit hash just by guessing and checking? What kind of computer would that take? Cryptocurrency video: https://youtu.be/bBC-nXj3Ng4 Thread for Q&A questions: http://3b1b.co/questions Several people have commented about how 2^256 would be the maximum number of attempts, not the average. This depends on the thing being attempted. If it's guessing a private key, you are correct, but for something like guessing which input to a hash function gives a desired output (as in bitcoin mining, for example), which is the kind of thing I had in mind here, 2^256 would indeed be the average number of attempts needed, at least for a true cryptographic hash function. Think of rolling a die until you get a 6, how many rolls do you need to make, on average?

The AES algorithm is a symmetric block cipher that can encrypt (encipher) and decrypt (decipher) information. Encryption converts data to an unintelligible form called ciphertext; decrypting the ciphertext converts the data back into its original form, called plaintext. The AES algorithm is capable of using cryptographic keys of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits. aes encryption and decryption aes encryption example aes encryption tutorial aes encryption online aes algorithm, aes encryption explained, aes algorithm tutorial, aes encryption and decryption algorithm, aes encryption algorithm, aes algorithm lecture, aes algorithm example, aes cryptography, aes encryption and decryption algorithm

The AES encryption is a symmetric cipher and uses the same key for encryption and decryption. The AES algorithm supports 128, 192 and 256 bit encryption, which is determined from the key size : 128 bit encryption when the key is 16 bytes, 192 when the key is 24 bytes and 256 bit when the key is 32 bytes. The methods provided by the library accept also a string password instead of a key, which is internally converted to a key with a chosen Hash function. The optional initialization vector (IV) size is 16 bytes, which is the block size of the algorithm. This is summarized in the table below: #selfhostwcf, #p2pnetworkprogramming,#netcorecommerce

Many years ago I came across a clickable flash animation that explained how the Rijndael cipher works. And even though Rijndael is pure, complex math, the animated visualizations made the whole process so crystal clear that I had to bend down to the floor afterwards to pick up my dropped jaw. Since then I know how powerful animated visualizations can be, even (or rather especially) for abstract and/or complex topics. When I started my Go blog, I knew I had to use animations because they are worth a thousand words. I did the same in my Go videos that you can find over here in my channel, and also in my Go course. This video is a recoding of the flash animation while I click through it. The flash animation is still available at formaestudio.com (link below), but no sane browser would agree to play any flash content anymore, so a video capture is the best we can get. I hope the pace of clicking through the steps is just right for you. NOTE: The video has no audio part. This is not a bug, the Flash animation simply had no sounds.

Hi guys we will learn in this tutorial series about the basics of cryptography and how to implement it in java. We will start with hashing to encryption and then to encoding. In hashing we will be using SHA-1, in ecryption we will focus on AES-128 and for encoding we will use Apache's Base64 encoder and decoder. Here we will implement the Code Block Chaining or CBC algorithim to understand Encryption in Java. We will understand what is IV parameter and what is its purpose and how to implement it here in java. We will also see the decryption in the same.

AES has swept away old faithful DES, and is now the workhorse of business and government cryptography. Our entire civil order relies on its integrity. Here we explain how it works, and discover how a string of simple crypto primitives combine to such a robust cipher for which no mathematical compromise was ever published.

In this video I'm explaining what is that Galois Counter Mode that provides Authenticated Encryption with Associated Data (AEAD). You must have heard it combined with AES, and maybe used in TLS, ... This is just a small explanation, you can get more on the NIST specs. Errata (thanks to Casper Kejlberg-Rasmussen in the comments) error at 11:21, the last M_H that is applied before going into the TAG should not be there if you compare your drawing to the diagram on https://en.wikipedia.org/wiki/Galois/Counter_Mode.

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.

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...?
