 ## 更新日志
 + v3.0.0
-  - Node.js 10.0.0之后不再推荐使用`crypto.createCipher()`, 所以 本库的`cipher()`方法, 内部改为调用`cipheriv()`
+  - Node.js 10.0.0之后不再推荐使用`crypto.createCipher()`, 所以 本库的`cipher()`方法, 内部改为调用`cipheriv()` (Node.js大于10.5.0时, 旧版本的不变)
 
 + v2.1.0
   - 优化`cipher()`等公钥加密方法的`key`和`iv`的默认值为`crypto.scryptSync('', '', 16)`
