index | next in thread | raw e-mail
I have a FreeBSD box with 2.2.7-STABLE on it, and
non-traditional encryption installed:
ls -l /usr/lib/libcrypt*
lrwxrwxrwx 1 root bin 11 Oct 13 1998 /usr/lib/libcrypt.a
-> libscrypt.a
lrwxrwxrwx 1 root bin 16 Oct 13 1998
/usr/lib/libcrypt.so.2.0 -> libscrypt.so.2.0
lrwxrwxrwx 1 root bin 15 Oct 14 1998
/usr/lib/libcrypt_p.a -> libdescrypt_p.a
For a resaon to do with some web authentication on an
offsite server we have bought space on, I have a need to
generate encrypted passwords in traditional, 13 character
UNIX style.
At present, a short C stub, when compiled and run with
bash-2.01# cc pw.c -lcrypt
bash-2.01# ./a.out
$1$_pa$DxOQFT8SEpBphLqHX/W4g1
is spitting out 32 character passwords.
#include <stdio.h>
main() {
const char *key = "password";
const char *setting = "_pa";
printf ("%s\n", crypt(key, setting));
}
man 3 crypt mentions "Traditional crypt", but I don't seem
to be able to use crypt in traditional fashion as things
are. Presumably I just need to find a copy of the trad UNIX
crypt.a libraries and link against those?
Thanks,
Adam.
