This is NOT the same thing, but I wrote it for the same
purpose.
Create a file containing user:password in plain text format.
e.g.
yourname:yourpassword
anothername:anotherpassword
Run "crypt filename >passwd_file", replacing filename with
the name of the file that contains this data, and passwd_file
with the name of the user/password file (typically .htaccess).
#include <stdio.h>
#include <unistd.h>
#include <string.h>
#include <time.h>
const char ll[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz.";
char *
salt(void)
{
static char buf[32];
int i;
for (i=0; i < 8; i++)
buf[i] = ll[rand() % sizeof(ll)];
buf[i] = '\0';
return buf;
}
int
main(int argc, char * argv[])
{
int carg = 0;
srand((unsigned)time(NULL) ^ getpid());
while (++carg < argc)
{
char * argp = argv[carg];
FILE * fp = fopen(argp, "r");
if (fp == NULL)
perror(argp);
else
{
char tmp[256];
while (fgets(tmp, sizeof tmp, fp) != NULL)
{
char * p = strchr(tmp, '\n');
if (p != NULL)
*p = '\0';
p = strchr(tmp, '\r');
if (p != NULL)
*p = '\0';
p = strchr(tmp, ':');
if (p == NULL)
p = tmp;
else ++p;
strcpy(p, crypt(p, salt()));
printf("%s\n", tmp);
}
fclose(fp);
}
}
return 0;
}
