Description:

Message Digest #4 is a 128-bit hashing algorithm; it is quick but not sufficiently strong for cryptographic use (duplicates can be found very efficiently). It provides sufficient mixing to have an avalanche effect: any change in input changes the output completely.

Example:

#include <stdio.h>
#include <ccan/md4/md4.h>

// Provide MD4 sums of the input strings.
int main(int argc, char *argv[])
{
        unsigned int i, j;
        struct md4_ctx ctx;

        for (i = 1; i < argc; i++) {
                md4_init(&ctx);
                md4_hash(&ctx, argv[i], strlen(argv[i]));
                md4_finish(&ctx);
                for (j = 0; j < 16; j++)
                        printf("%02x", ctx.hash.bytes[j]);
                printf("\n");
        }
        return 0;
}
