I removed static and inline, It was a mistake from an earlier project. Opps.
I prefer K&R bracing, I like it becuase its clean. Please do explain why thats not good.

I made a few adjustments and Its still not working. I find it very depressing, because to me the code is right. Clearly its not, otherwise I would giggling with self achievement.

I am really starting to think about making page on how to write a cipher for dummies by a dummy!

I appreciate the help, thanks.

I think I am going to have to printf every line until I see my error.

Included is what I have done.

Code:

 


   unsigned int last;
   unsigned int output;
   unsigned int current_byte;
   int mode;
   int i;

  case decrypt:
       i = 0;
       current_byte = fgetc(plain_text);
       printf("C[%d] = '%02X'\n", i, current_byte);
       output = baldr_decrypt(current_byte,*user_key);
       printf("D(C[%d]) = '%02X'\n", i, output);
       output = output ^ iv;
       printf("P[%d] = '%02X'\n", i, output);
       fputc(output, cipher_text);

       last = current_byte;
       i += 1;
       printf("\n");

       /* while we are still reading data */
       while ((current_byte = fgetc(plain_text)) != EOF)
       {
           /* has user key expired ? if so reset it*/
           if (*user_key == '\0')
               user_key = argv[1];

           printf("C[%d] = '%02X'\n", i, current_byte);
           output = baldr_decrypt(current_byte, *user_key);
           printf("D(C[%d]) = '%02X'\n", i, output);
           output = output ^ last;
           printf("P[%d] = '%02X'\n", i, output);

           last = current_byte;
           user_key++;
           /* write current byte */
           fputc(output, cipher_text);

           i += 1;
           printf("\n");
       }
       break;
