解析消息和键的数据时,c#和JavaScript都是相同的:

从散列的字节数组中将键确定为子数组(包括索引10到索引34),该子数组必须转换回具有等效内容的
字数组
,即行:
newKeyx = crypto.enc.Utf8.parse(newKeyx);
必须替换为:
newKeyx = byteArrayToWordArray(newKeyx);
通过此更改,NodeJS代码返回与C#代码相同的结果
转换
WordArray byte array
(以及这些转换所需的所有函数)实际上并不是必需的,因为作为替代方案,密钥也可以仅使用以下函数派生:
顺便说一下,-模式是不安全的,应该使用性能更高的AES来代替。在c#中,KeyOffSet!=键偏移。然后从IX10开始复制,但是newKeyx只有24字节长,所以哈希值只有14字节?你确定?在javascript中,它至少是34。检查keybyte的长度。然后javascript可能会用salt或rounds填充前10个字节,你也必须在c#中这样做。@Charles,对不起。那只是个打字错误。我试图使代码更简单,以便更清晰。我现在做了改变。请看我的编辑。谢谢。试着逐行比较byte[]数组,看看它们什么时候不同。是keybyte js==keybyte c#,等等。我无法测试您的javascript,因为有函数missing@Charles我会把一切都发出去。我比较了每一行,它们完全相同。@Charles请查看我的编辑,其中包括所有方法。非常感谢您,先生!!!!!!!!!!!!!!!非常感谢。非常感谢。非常感谢。
