Hello.
I'm trying to do SHA-512 password encryption, but the result is really
weird on Cygwin:
# On Cygwin(either 32 or 64) 2.4.1-1, latest updates with crypt 1.1-1,
libcrypt0 1.1-1, libcrypt-devel 1.1-1
$ crypt '$6$7dl4B0fKUimdnR$' test_value
$6wOs/zKP2jDM
$ python -c 'import crypt; print crypt.crypt("test_value",
"$6$7dl4B0fKUimdnR$")' # Python 2.7.10
$6wOs/zKP2jDM
$ perl -e 'print crypt("test_value", "\$6\$7dl4B0fKUimdnR\$")."\n"' #
Perl v5.22.1
$6wOs/zKP2jDM
Am I missing something?
On other system, I get a more expected result:
# On Ubuntu 15.04
$ mkpasswd --method=SHA-512 test_value 7dl4B0fKUimdnR
$6$7dl4B0fKUimdnR$f6gCu.3IfrxhsnJKFnusDH.UudC.lLOSB1G3D1bIboWxlixzBy2xO/3rCKHmzfwekCTvmQd11bPdcsJOaLkCJ.
Not SHA-512, see
/usr/share/doc/crypt/crypt.README
This is the DES-crypt package Version 1.1
It provides a static library libcrypt.a as well as a shared library
cygcrypt-0.dll together with a link lib libcrypt.dll.a, which export
the functions
crypt(3)
encrypt(3)
setkey(3)
The passwords created by crypt(3) are 56 bit DES encrypted and are
100% identical to those created by the Linux crypt().
