     The used csv file had the following format:

     <rounds>,<salt(8byte)> (when no rounds parameter was given,
                             rounds were set to zero.)

     The salts have been generated by crypt_gensalt on OpenSolaris.


     Test X.0: checks the password is encryptable with the full hash
               as setting.
     Test X.1: checks the password is encryptable with the initially
               used salt as setting.
     Test X.0: checks for the bug in Sun's original implementation
               is present.
               See:  http://passlib.readthedocs.io/en/stable/lib/passlib.hash.sun_md5_crypt.html#smc-bare-salt
