You have to check your libcrypt  try this

ls -l /usr/lib/libcrypt*

If the symbolic links point to libdescrypt*, youre using DES, if it points
to libmd5crypt*, youre
using MD5.

I read that the symbolic link is pointing to libdescrypt* you're useing DES
if it points to libmd5crypt* you have MD5

Here is my output
ninofision:~$ ls -l /usr/lib/libcrypt*
lrwxrwxrwx  1 root  wheel       13 Aug 29 03:10 /usr/lib/libcrypt.a ->
libdescrypt.a
lrwxrwxrwx  1 root  wheel       14 Aug 29 03:10 /usr/lib/libcrypt.so ->
libdescrypt.so
lrwxrwxrwx  1 root  wheel       16 Aug 29 03:10 /usr/lib/libcrypt.so.2 ->
libdescrypt.so.2
lrwxrwxrwx  1 root  wheel       15 Aug 29 03:10 /usr/lib/libcrypt_p.a ->
libdescrypt_p.a
-r--r--r--  1 root  wheel  1275196 Nov 20  2000 /usr/lib/libcrypto.a
lrwxrwxrwx  1 root  wheel       14 Aug 29 03:10 /usr/lib/libcrypto.so ->
libcrypto.so.1
-r--r--r--  1 root  wheel   782200 Nov 20  2000 /usr/lib/libcrypto.so.1
-r--r--r--  1 root  wheel  1362554 Nov 20  2000 /usr/lib/libcrypto_p.a

I guess I'm with DES
