this is right, Rcon(0) = 01000000 Rcon(1) = 02000000 Rcon(2) = 04000000 Rcon(3) = 08000000 Rcon(4) = 10000000 Rcon(5) = 20000000 Rcon(6) = 40000000 Rcon(7) = 80000000 Rcon(8) = 1B000000 Rcon(9) = 36000000 Rcon(10) = 6C000000 Rcon(11) = D8000000 Rcon(12) = AB000000 Rcon(13) = 4D000000 Rcon(14) = 9A000000 but I don't know what is the meaning of Rcon[256] that was posted in wikipedia.. I don't know how to lookup in that table.

thanks for that @Paulo, but what is the used of Rcon[256], that will be found here en.wikipedia.org/wiki/Rijndael_key_schedule under Rcon.

there is a three step in key expansion, rotation, after rotation, the every 8bit in my 32bit key will change using s-box and the RCON.
