AES Encryption 2: AddRoundKey, SubBytes and ShiftRows
 
21:09
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.

AES Encryption 5: Expand Keys and Encryption Flow
 
32:51
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...?

Cryptography in Java. 7- CBC AES128 encryption implementation in Java
 
10:05
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.

Caesar Cipher Encryption and Decryption in Java
 
09:18
Ceasar Cipher in Java Hi!! In this video I'll be coding ceasar cipher encryption and decryption using Java Caesar Cipher is subsitution cipher, its algorithm is as following: - Take alphabetic message (A to Z) - Take a key (1 to 26) (1 being A and 26 being Z) - To encrypt, left-shift or right-shift message letter by letter by the value of key For example if message is "ABC" and key is 1 and we are performing right-shift then encrypted text will be A+1 = B, B+1 = C, C+1 = D. ABC = BCD, BCD being encrypted text. - To decrypt, left-shift or right-shift the message letter by letter opposite to the shift performed in encryption by the value of key For example if encrypted text is "BCD" and key is 1 and we are performing left-shift then encrypted text will be B-1 = A, C-1 = B, D-1 = C. BCD = ABC, ABC being decrypted text.

[C#] Encrypting Files with AES
 
04:13
A simple C# application that encrypts files with AES (Advanced Encryption Standard). As shown in the video, an encrypted file can only be decrypted with the same key (case sensitive). Trying to decrypt it with an invalid key will result in an exception. Note: This implementation, with a bit of rework, can work fast with lots of small files. Instead of computing the cipher for every file, it computes it once (See GetCipher()) and uses it for every file. It cannot encrypt large files. For that, you need to chain streams instead of reading the whole file in a byte array. I have a WinForms implementation on my GitLab page (it chains streams but doesn't use GetCipher()): https://gitlab.com/UnexomWid/PadlockU --Music: Artist: Nicolai Heidlas Title: Futuristic Technology https://soundcloud.com/nicolai-heidlas --Links: Website: https://unexomwid.github.io Github: https://github.com/UnexomWid Twitter: https://twitter.com/UnexomWid

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
