Hello i have to do this :
glibc crypt() function, using salt $1$abcdefgh$

cryptPw = crypt(plainPw, "$1$abcdefgh$")

I can do it in python, with package i need?
Thanks

Is that what it's supposed to return?

This particular post did get get through, it is even marked as read over
here.

Sorry for any confusion my pointless answer may have caused.

seeing this I thought about using ctypes for AES (or similar) crypto
function. A bit of google searching I've come to
http://code.google.com/p/ctypescrypto/

just FYI

ctypescrypto does not appear to be maintained, but I've started
a similar project called evpy (http://gitorious.org/evpy) that also
provides envelope encryption. Comments are welcome- we're
probably going to be doing our first release sometime towards
the middle of next month.

Thanks
The result is correct i obtain the same with ctypes and crypt module,
so i think that is better to use the crypt module is correct?

Yes, use the crypt module.

Be aware that the beginning of the salt string determines the
type of hash you're using, and it looks to me like that's the
old-style MD5-based hash. It's far from 'broken', but it has a
few issues. Better would be to move to the SHA512-based
$6$ if your platform supports it.
