AES is a block cipher algorithm that can be used in various modes of operation. Learn about the different libraries, applications and modes of AES, such as CBC, CTR, GCM and more.
Learn about the substitution box (S-box) used in the Rijndael cipher, the basis of the Advanced Encryption Standard (AES) algorithm. See the forward and inverse S-box tables, the Nyberg S-box transformation, and the affine transformation.
Learn about the AES instruction set, a set of instructions that perform AES encryption and decryption efficiently. Find out which Intel processors support AES-NI, the first major implementation of AES-NI, and compare it with other architectures and hardware accelerators.
void gmix_column (unsigned char * r) {unsigned char a [4]; unsigned char b [4]; unsigned char c; unsigned char h; /* The array 'a' is simply a copy of the input array 'r' * The array 'b' is each element of the array 'a' multiplied by 2 * in Rijndael's Galois field * a[n] ^ b[n] is element n multiplied by 3 in Rijndael's Galois field */ for (c = 0; c < 4; c ++) {a [c] = r [c]; /* h is set to ...
Comparison of implementations of message authentication code (MAC) algorithms. A MAC is a short piece of information used to authenticate a message—in other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed in transit (its integrity).

Learn how the Advanced Encryption Standard expands a short key into a number of round keys for encryption. See the key schedule algorithm, the round constants, and the key schedule schematic for different AES variants.
Crypto++ (also known as CryptoPP, libcrypto++, and libcryptopp) is a free and open-source C++ class library of cryptographic algorithms and schemes written by Wei Dai.Crypto++ has been widely used in academia, student projects, open-source, and non-commercial projects, as well as businesses. [1]
