my implementation of AES in C++
word size: 32 bit
key length: 128 bit -> 4 words
block size: 128 bit -> 4 words
number of rounds: 10
Note
The program will ask you to enter the key
The key in my implementation is kind of like a password provided by user
If the string provided by user is too long -> only first 16 bytes are treated as a key
If it is too short -> the remaining bytes are filled with '0'
./cpp-aes -e input_file output_file./cpp-aes -d input_file output_file
