I've attached a couple of Perl scripts that do what you have asked for -
and more.  The scripts require the Authen::Passphrase module from CPAN,
and they accept a wordlist (such as JtR's default password.lst) on
standard input and produce /etc/passwd-like or PWDUMP-like entries on
standard output.  This covers all of the hash types supported by JtR
natively, and NTLM.  The plaintext passwords are placed into the GECOS
field, which lets the "single crack" mode crack them instantly.



use Authen::Passphrase::DESCrypt;
use Authen::Passphrase::BigCrypt;
use Authen::Passphrase::MD5Crypt;
use Authen::Passphrase::BlowfishCrypt;

$u = 0;
while ($p = <>) {
	next if ($p =~ /^#!comment/);
	chomp $p;
	$h = Authen::Passphrase::DESCrypt->new(passphrase => $p, salt_random => 12);
	print "u$u-des:", $h->as_crypt, ":$u:0:$p", "::\n";
	if (length($p) > 8) {
		$h = Authen::Passphrase::BigCrypt->new(passphrase => $p, salt_random => 12);
		print "u$u-bigcrypt:", $h->salt_base64_2, $h->hash_base64, ":$u:0:$p", "::\n";
	$h = Authen::Passphrase::DESCrypt->new(passphrase => $p, fold => 1, nrounds => 725, salt_random => 24);
	print "u$u-bsdi:", $h->as_crypt, ":$u:0:$p", "::\n";
	$h = Authen::Passphrase::MD5Crypt->new(passphrase => $p, salt_random => 1);
	print "u$u-md5:", $h->as_crypt, ":$u:0:$p", "::\n";
	$h = Authen::Passphrase::BlowfishCrypt->new(passphrase => $p, cost => 5, salt_random => 1);
	print "u$u-bf:", $h->as_crypt, ":$u:0:$p", "::\n";


use Authen::Passphrase::LANManager;
use Authen::Passphrase::NTHash;

$u = 0;
while ($p = <>) {
	next if ($p =~ /^#!comment/);
	chomp $p;
	$lm = Authen::Passphrase::LANManager->new(passphrase =>
		length($p) <= 14 ? $p : "");
	$nt = Authen::Passphrase::NTHash->new(passphrase => $p);
	print "u$u:$u:", $lm->hash_hex, ":", $nt->hash_hex, ":$p", "::\n";
