Here is the program :-

#include <stdlib.h>
#include <time.h>
#include <stdio.h>
#include "aes.h"
 
 
void encrypt(const char *fileIn, const char *fileOut,
    const unsigned char *key);
void decrypt(const char *fileIn, const char *fileOut,
    const unsigned char *key);
 
int main() {
  const unsigned char key[] = "my key";
 
  srand(time(NULL));
 
  aes_init();
  encrypt("main.c", "main.c.encrypted", key);
  decrypt("main.c.encrypted", "main.c.decrypted", key);
 
  return 0;
}
 
void encrypt(const char *fileIn, const char *fileOut, 
    const unsigned char *key) {
  int i;
  aes_encrypt_ctx ctx[1];
  unsigned char iv[16]; /* initialisation vector */
  unsigned char inBuffer[200], outBuffer[200];
  FILE *inFile = fopen(fileIn, "rb");
  FILE *outFile = fopen(fileOut, "wb");
 
  /* pick a random initialisation vector */
  for(i = 0; i < 16; ++i)
    iv[i] = rand() & 0xFF;
  fwrite(iv, 1, 16, outFile);
 
  aes_encrypt_key256(key, ctx);
  while((i = fread(inBuffer, 1, sizeof(inBuffer), inFile)) > 0) {
    aes_ofb_crypt(inBuffer, outBuffer, i, iv, ctx);
    fwrite(outBuffer, 1, i, outFile);
  }
 
  fclose(inFile);
  fclose(outFile);
}
 
void decrypt(const char *fileIn, const char *fileOut, 
    const unsigned char *key) {
  int i;
  aes_encrypt_ctx ctx[1];
  unsigned char iv[16]; /* initialisation vector */
  unsigned char inBuffer[200], outBuffer[200];
  FILE *inFile = fopen(fileIn, "rb");
  FILE *outFile = fopen(fileOut, "wb");
 
  /* read initialization vector from file */
  if(fread(iv, 1, 16, inFile) < 16) {
    fclose(inFile);
    fclose(outFile);
    return; /* error: file doesn't even contain an initialisation vector */
  }
 
  aes_encrypt_key256(key, ctx);
  while((i = fread(inBuffer, 1, sizeof(inBuffer), inFile)) > 0) {
    aes_ofb_crypt(inBuffer, outBuffer, i, iv, ctx);
    fwrite(outBuffer, 1, i, outFile);
  }
 
  fclose(inFile);
  fclose(outFile);
}

What is exactly the compilation error?

is the aes.h file in your path? I think, this throws your error.

What name have you gives for the aes? aes.c?

Exactly , that throws as "compilation error".. "no such file or directory ". 
Actually , i am  not clear of this weather it requires path or not .
I have given file name as aes.c.this is what i am getting..

root@mymo-HP-Compaq-dc7700-Small-Form-Factor:/home/mymo/Desktop/mac# cc aes256.c -o aes256
aes256.c:4:17: fatal error: aes.h: No such file or directory
 #include "aes.h"
                 ^
compilation terminated.

It needs the header file to compile. Have you downloaded this file? If 
so, you have to download the header file too and put it in the directory 
where aes.c is, so it could be found. The feader file is needed, because 
it holds the definitions of the file.

It could also be written for yourself. I can't give it to you, but it 
has to be easy to dine it, because the file you have is very short.

Sincerely, Markus

Try asking in a C newsgroup.  This one is for PHP - hence the "PHP" in
its name.

When you ask in the correct place, you get better answers.

Looks like c, not PHP. Try a c programming newsgroup.
