The advanced Encryption standard (AES) is a symmetric-key square figure calculation for comfy and grouped statistics encryption and decoding. The national Institute of standards (NIST) affirmed AES as Federal records Processing standards which suggests use  it in all sensitive characterized facts. it’s miles the maximum popular symmetric encryptionalgorithm additionally known as the Rijndael call is a combination of the nameof inventors Joan Daemen and Vincent Rijmen. it is one of the maximum famousand maximum extensively used algorithms inside the world, the quantity ofrounds relies upon on key size 10 rounds if the key size is 128 bits, 12 roundsif key size is 192 bits and 14 rounds if key size is 256 bits.
