+/**
+ * md4 - MD4 Message Digest Algorithm (RFC1320).
+ *
+ * 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;
+ *     }
