AES is based on the Rijndael cipher developed by two Belgian cryptographers, Joan Daemen and Vincent Rijmen, who submitted a proposal to NIST during the AES selection process. Rijndael is a family of ciphers with different key and block sizes. F

Modern symmetrical encryption systems use a starting “key” that is up to 256 bits long (for us civilians anyway) and combine this with an initialization-vector (also up to 256 bits long). By applying the vector to the key through some scary mathemati
