不过，问题是加载证书的函数并没有请求使用加密证书的密码。

The trouble, though, is that the functions that load the certificates do not ask for a password for encrypted certificates.

现在提示用户输入密码的回调函数已经创建好了，然后我们就可以使用真正导入证书的函数了。

Now that the callback function has been created so the user can be prompted for a password, the functions to actually import the certificates can be used.

因此，若无密码键入，传递到该函数的是未初始化的变量和脚本错误结果。

Hence, with no password entered, the function is passed an uninitialized variable and a script error results.

The answer is I can't. OK, in the simple case of integers I can, but in the case of something more complex like faces or fingerprints or passwords for that matter, it's hard to design a hash function that has completely even distribution, meaning that it takes any input into exactly one output spot.

答案是我不能，好吧,在简单的整数的例子中,我可以做到，但是在一些更复杂的场景中,比如面部，指纹，密码相关的问题中，很难设计一个哈希函数具备完全平均的分配,也就是说，做到对任一输入，可以准确地得到相应的唯一输出,因此在一个哈希问题中。
