The code above only supports 128bit of plaintext encryption which is a block cipher of AES algorithm. If your plaintext is more than that there are several ways(AES modes) to encrypt data, such as ECB (Electronic Code Book), CBC (Cipher Block Chaining), CFB (Cipher Feedback), For deta...

CODE IS PROVIDED FOR ALL TO UNDERSTAND THE AES ALGORITHM. Comments are provided as needed to understandthe program. But the user must read some AES documentation to understandthe underlying theory correctly. It is not possibleto describe the complete AES algorithm in detail here. For the ...
Now that we know what the AES algorithm is supposed to do, let's see what its implementation looks like as a vertex program. The code given throughout this chapter uses C-style macros and comments to improve readability of the assembly language. These—like those in theROT8macro...
