Example usage creates buffer overflow

[lseekio]

Example Usage: Output overflows buffer to stdin causing getchar() to close the console immediately after execution.

	uint8_t in[8] = {0x58, 0x7c, 0xb3, 0x98, 0xfe, 0x82, 0xff, 0xda};
	uint8_t out[32];

	shake256(out,256,in,sizeof(in));
	printArray(out,32);
	getchar();

Output should be in bytes not bits. also noted by warmist .
Example where console windows remains open as it should

	uint8_t in[8] = {0x58, 0x7c, 0xb3, 0x98, 0xfe, 0x82, 0xff, 0xda};
	uint8_t out[32];

	shake256(out,32,in,sizeof(in));
	printArray(out,32);
	getchar();

I was getting bad results with sizeof(in) and changed it to strlen instead

Just for sake of completion I'll pate my code program.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "keccak-tiny.h"

int main()
{
   uint8_t *in = "The quick brown fox jumps over the lazy dog";
   uint8_t out[64];
   int      i;
   len = strlen(in);
   shake256(out, 64, in, strlen(in));

   printf("\nThe SHAKE-256 hash of '%s' is:\n", in);
   for ( i = 0; i < 64; i++ )
   {
      printf("%02x", out[i]);
   }

   printf("\n");

   return 0;

}
