Generating a salted hash compatible with shadow(5) is a rather simple task.
|
||
|
|
|
||
|
|
If you haven't read the shadow(5) man page yet, I highly recommend it:
|
||
|
|
|
||
|
|
man 5 shadow
|
||
|
|
|
||
|
|
There are many ways in which you can generate a salted hash.
|
||
|
|
|
||
|
|
0.) Debian can do this with the mkpasswd utility (it's in Arch's AUR as debian-whois-mkpasswd):
|
||
|
|
|
||
|
|
mkpasswd --method=sha-512 --salt=aBcDeFgHiJ PASSWORD
|
||
|
|
|
||
|
|
(If a salt is not provided, one will be automatically generated. That is is the suggested method.)
|
||
|
|
|
||
|
|
1.) perl (PoC script welcome):
|
||
|
|
|
||
|
|
perl -e 'print crypt("PASSWORD","\$6\$aBcDeFgHiJ\$") . "\n"'
|
||
|
|
|
||
|
|
2.) python (extras/bin/hashgen.py):
|
||
|
|
|
||
|
|
python -c "import crypt, getpass, pwd; print crypt.crypt('PASSWORD','\$6\$aBcDeFgHiJ\$')"
|
||
|
|
|
||
|
|
3.) php:
|
||
|
|
|
||
|
|
php -r "\$password = readline('Password: '); \$saltRaw = random_bytes(8); \$salt = base64_encode(\$saltRaw); \$result = crypt(\$password,'\$6' . '\$' . \$salt .'\$'); print \$result . \"\n\";"
|
||
|
|
|
||
|
|
4.) even grub-crypt (if using legacy grub):
|
||
|
|
|
||
|
|
/sbin/grub-crypt --sha-512
|
||
|
|
|
||
|
|
The end-product should look something like this:
|
||
|
|
|
||
|
|
$6$aBcDeFgHiJ$Yh342vFH7MOjPNu9InFymD1Dd42i5cFsr1cTWdpKGNIkbRGR/ZKQDRPJ1ZeeGb7y894Tfh3iWZIJKu3phlsqQ1
|
||
|
|
|
||
|
|
If it doesn't, you did something incorrectly.
|
||
|
|
Note that different hashes/the PoC scripts will result in a different string, but it should be the same length.
