Hi Everybody,
I am an electronics engineer. I want to an application with a microcontroller and I need your helps.
I have some questions.
1-) How I can load a data to AES (Rinjdael)source code with c. I have to use with c .
Source code is here : http://svn.saddi.com/rijndael/branch...ndael-fst-3.0/
please help me.
By "load" do you mean encrypting and decrypting data using the Rijndael methods? If so, I can provide some assistance. I have a similar situation where I use the Rijndael Electronic Code Book (ECB) for encrypting /decrypting data sent to/from a networked security controller. Thus, if your using the ECB method, I can provide some useful C code.Quote:

Yes, I mean by '' load '' encrypting and decrypting data using the Rijndael method. I need a C code that using AES rijindael 128 bit.
When you send the code, Please tell how i can use it.
Thanks a lot.
The code below came from my Rijndael class. It has to be compiled as C++. But it can be converted to plain C by addressing the syntactical issues. Also, the only two functions that should be of concern to you are the Encrypt and Decrypt functions. All the other functions are unique to my implementation and are not relevant to the Rijndael encryption/decryption. So, the "cleaning up" of the code, I'll delegate to you.
Good luck!
EDIT: This is a 128 bit Electronic Code Book (ECB) Rijndael implementation

Hi BobS0327.
First I want to say my thanking.
So i could not use your code. Could you explain me the below code. How can i plaintext data in the below code?

Best regards...
Do you have an actual question, or are you just going to keep flooding the board with other peoples code?
Have you practiced using the code on your PC before making life harder and putting it on your embedded controller?
Of course, I have practiced two codes above, but I could not run them. And i don`t know how i can put plaintext data to code.
./a.out
Now run along.
Quzah.
pardon? I couldn`t understand ./a.? What is ./a.?Quote:

I did verify this code by using it to communicate with a networked security controller prior to posting it. So, it does work as a 128 bit Electronic Code Book (ECB) Rijndael implementation.
I've also just converted the code to plain vanilla C and tested it to verify that it does work. I could be persuaded to email you the plain vanilla C but I just don't have the time nor the inclination to deal with a lot of noob questions such as how to input plaintext into the encryption function. In other words, the code is yours but I'm not available for any additional support and I don't want to clutter this thead with a another humongous post.
BTW, your posting is missing at least one cipher function. ... It needs a lot of work.
PM me with your email for the source code and be on your way.
EDIT: FYI... to input plain text make the following change. I think you're confused by the string of hex values.
Code:change
char szDataIn1[81] = "0xFF-0xE3-0x22-0xDE-0x57-0xF7-0x89-0xE6-0x55-0xE7-0x0D-0xA3-0x34-0x4F-0xDD-0x42";
to
char szDataIn[33] = "Hello Gumit, How are you today??"; // plain text

No, they are not the same. I have taken the author's test file named Rijndael-test-fst.c and removed all the unecessary functions etc. This test file was just their proof that their implementation of Rijndael was highly optimized by using test vectors. I used what I needed from their various testing methods to do the Rijndael encryption and decryption. In other words, test.c is the "bare bones" version of Rijndael-test.fst.c. You still have to compile test.c with the author's other two Rijndael files, Rijndael-alg-fst.c and rijndael-api-fst.c since I used their implementation in a "bare bones" fashion to do the encrypt/decrypt stuff.Quote:

Hi,
Finally I have worked the code, :).
But I have a problem :(. I am trying upload the code to ST72f63BU6 microcontrollers that has 1k RAM. When I try working the code, it gives me overflow error. I don`t think so, that it costs much storage.
How can i solve this problem?
Regards...
