Hi!!!

i'm working on web design and I need to create encripted passwors, I tried with
a modified version of NCSA htpasswd program:

genpass.c

# more genpass.c
/*
 * htpasswd.c: simple program for manipulating password file for NCSA httpd
 *
 */

#include <sys/types.h>
#include <stdio.h>
#include <string.h>
#include <sys/signal.h>
#include <stdlib.h>
#include <time.h>

#define LF 10
#define CR 13

#define MAX_STRING_LEN 256

char *tn;



/* From local_passwd.c (C) Regents of Univ. of California blah blah */
static unsigned char itoa64[] =         /* 0 ... 63 => ascii - 64 */
        "./0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";

to64(s, v, n)
  register char *s;
  register long v;
  register int n;
{
    while (--n >= 0) {
        *s++ = itoa64[v&0x3f];
        v >>= 6;
    }
}

char *crypt(char *pw, char *salt); /* why aren't these prototyped in include */

void add_password(char *user,char *pw) {
    char *cpw, *pru, salt[3];

    (void)srand((int)time((time_t *)NULL));
    to64(&salt[0],rand(),2);
    cpw = crypt(pw,salt);
    printf("%s",cpw);
}
main(int argc, char *argv[]) {
    char user[MAX_STRING_LEN];
    char line[MAX_STRING_LEN];
    char l[MAX_STRING_LEN];
    char w[MAX_STRING_LEN];
    char command[MAX_STRING_LEN];
    int found;

    tn = NULL;
    add_password(argv[1],argv[2]);
}

but i get this mesg

gcc -o genpass genpass.c
/var/tmp/cc0159851.o: Undefined symbol `_crypt' referenced

any idea?

Thanx
