React-Native + crypto：如何在 React-Native 中生成 HMAC？

【问题描述】：

我尝试过加密，这显然行不通，因为它取决于节点运行。所以，我转向crypto-browserify，但我相信存在依赖性问题。如果有人可以提供帮助，我将不胜感激。

作为参考，我之前使用过这样的加密：

crypto.createHmac('md5', "MY_KEY").update('SOMETHING_TO_ENCRYPT').digest('hex');

编辑

我正在尝试加密一个用密钥加盐的字符串。上面的代码是我以前用来实现这一点的。我需要在 React-Native 中做一个类似的操作。

当尝试使用 crypto-browserify（我认为可以在 React-Native 中使用）时，我在打包程序中得到以下信息：

【问题讨论】：

我不明白为什么这会被否决？

我的错，我认为我表达的不够明确。这是一些输出和说明。

browserify 中似乎有一个 ASN.1 模块，但我想知道为什么根本需要它...

我不确定。我对围绕 RN 的所有嗡嗡声感到惊讶，因为这在任何地方都没有得到进一步解决。我现在正在为它编写一个本地模块，以防万一没有解决方案。

我在 0.12.0 版本上使用带有 RN 的 npm 包 crypto-js，它运行完美。也许试试那个包？

【参考方案1】：

正如 Nader Dabit 所指出的，在 0.12.0 版本上使用带有 RN 的 npm 包 crypto-js 似乎可以解决问题。

【参考方案2】：

2020 年，你现在应该使用 v3.3.0 的 crypto-js。
