WebIt supports encryption key sizes of 128, 192, and 256 bits and handles data in 128-bit blocks. Rijndael as Advanced Encryption Standard DES has been in use since 1977. However, by the early 2000s, it began to show security weaknesses. It became obvious that threat actors could use brute-force attacks and crack DES. WebAES, specifically, inversion in GF(2^8) (which is the source of non-linearity in the AES-like block cipher design). This operation is the major element that speeds the instructions …
