New page

The Message-Digest Algorithm 5 (MD5-Hash) is provided by the optional Gorp Library.

== Test Suite Source Code ==

The contents of nutapp/testmd5/testmd5.c is:

<source lang="c">
#include <dev/board.h>
#include <gorp/md5.h>

#include <stdio.h>
#include <string.h>

static MD5CONTEXT context;
static uint8_t digest[16];

static char *test[] = {
"",
"a",
"abc",
"message digest",
"abcdefghijklmnopqrstuvwxyz",
"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789",
"12345678901234567890123456789012345678901234567890123456789012345678901234567890",
NULL
};

int main(void)
{
int i;
int j;

NutRegisterDevice(&DEV_CONSOLE, 0, 0);
freopen(DEV_CONSOLE.dev_name, "w", stdout);
puts("\nMD5 Test Suite " __DATE__ " " __TIME__);

for (i = 0; test[i]; i++) {
NutMD5Init(&context);
NutMD5Update(&context, (uint8_t *)test[i], strlen(test[i]));
NutMD5Final(&context, digest);
printf("MD5 (\"%s\") = ", test[i]);
for (j = 0; j < 16; j++) {
printf("%02x", digest[j]);
}
putchar('\n');
}
for (;;);
return 0;
}
</source>

== Test Suite Makefile ==

Note, that lines must me intended with tabs, not spaces.

<pre>
PROJ = testmd5

include ../Makedefs

SRCS = $(PROJ).c
OBJS = $(SRCS:.c=.o)
LIBS = $(LIBDIR)/nutinit.o -lnutpro -lnutnet -lnutgorp -lnutfs -lnutcrt -lnutos -lnutdev -lnutarch

all: $(OBJS) $(TARG) $(ITARG) $(DTARG)

include ../Makerules

clean:
-rm -f $(OBJS)
-rm -f $(TARG) $(ITARG) $(DTARG)
-rm -f $(PROJ).map
-rm -f $(SRCS:.c=.lst)
-rm -f $(SRCS:.c=.d)
</pre>

== Test Suite Result ==

Tested on the Elektor Internet Radio, the output equates to http://tools.ietf.org/html/rfc1321.
