我已将$2y$10$zQaDT8hXM4pLmBdwN0xEseda/oKJAQKMKMzUrV8jbs6Epz28BXzBS密码（qwe）的值（）加密。但是当我验证时，我得到了错误的结果哈希值。

mysql> select '$2y$10$zQaDT8hXM4pLmBdwN0xEseda/oKJAQKMKMzUrV8jbs6Epz28BXzBS' = encrypt('qwe', '$2y$10$zQaDT8hXM4pLmBdwN0xEseda/oKJAQKMKMzUrV8jbs6Epz28BXzBS') as is_valid; 
+----------+
| is_valid |
+----------+
|        0 |
+----------+

select encrypt('qwe', '$2y$10$zQaDT8hXM4pLmBdwN0xEseda/oKJAQKMKMzUrV8jbs6Epz28BXzBS') as hash;
+---------------+
| hash          |

| $2tBKnsbV2Szg |

md5 工作良好

mysql> select '$1$$.dCRcHz4ApIYzcA0g/qz3/' = encrypt('qwe', '$1$$.dCRcHz4ApIYzcA0g/qz3/') as is_valid; 
+----------+
| is_valid |
