Cryptography is the knowledge of using arithmetic to encrypt and decrypt data. It allows to store sensitive data or transmit it from corner to corner the Internet so that it cannot be read by anyone apart from the intended recipient. Various encryption systems are available, in that one of the most protected symmetric encryption procedures is Advanced Encryption Standard. Higher safety and speed of encryption/decryption is certified by operations like Sub Bytes, Mix Columns and Key Scheduling.
