Apr 22	comment	How to perform file encryption using 128-Bit AES? hm, I want to encrypt a examination file In my school where I am studying as part of my thesis, I think it should help the school to protect their examination from leakage.
Apr 22	comment	How to perform file encryption using 128-Bit AES? I don't have a programming problem, I have a problem on how can I encrypt it, what data should I get to the file to encrypt it...

Apr 22	comment	Does the Biclique attack on AES pose a credible risk to its security? But biclique attack is one of the known attack in AES, in biclique attack, is that really a threat in security of AES?
Apr 22	comment	Does the Biclique attack on AES pose a credible risk to its security? this is the one that i search over the internet.. computescotland.com/… I search about the weakness of AES, and I found this weaknesses, but there is no name that was derived in this attack..

Apr 21	comment	How to use RCON In Key Expansion of 128 Bit Advanced Encryption Standard 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.
Apr 21	comment	How to use RCON In Key Expansion of 128 Bit Advanced Encryption Standard 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.

Apr 21	comment	How to use RCON In Key Expansion of 128 Bit Advanced Encryption Standard 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.
