在角7中使用SJCL时，无法解析“./node_modules/SJCL”中的“crypto”

Question

我想在客户端加密数据，所以我找到了SJCL npm。

翻阅了他们的文件。然而，SJCL贡献者提供的文档较少，无法在ar角中实现这一点。

我试过以下几种方法。

我安装了软件包

1. npm安装--保存sjcl 之后，我尝试安装类型定义。
2. npm安装--保存sjcl @type/sjcl

这是我的package.json

{

"name": "project-name",

"version": "0.0.0",


  "scripts": {

    "ng": "ng",

    "start": "ng serve",

    "lint": "ng lint",

    "e2e": "ng e2e"

  },

  "private": true,

  "dependencies": {

    "@angular/cdk": "~7.1.0",

    "@angular/common": "~7.1.0",

    "ts-node": "~7.0.0",

    "tslint": "~5.11.0",

    "typescript": "~3.1.6"

  }
}

我也做过这件事

import * as sjcl from 'sjcl';

在我的部件里。

此外，我已经通过了这个链接Using SJCL library in Angular2。

当我运行角应用程序时，我

** WARNING in ./node_modules/sjcl/sjcl.js
Module not found: Error: Can't resolve 'crypto' in './node_modules/sjcl'**


**Note starts:**

used sjcl.encrypt("password", "data")
but after console.log(sjcl.encrypt("password", "data"))
it shows undefined

**Note ends:**

可能是我的笔记，不是那么完美，或者我定义错了。如何在没有此警告的情况下使用SJCL加密数据？

Answer 1

我使用了sjcl库作为我的react应用程序。但这一过程保持不变。

import sjcl from 'sjcl';

现在您可以使用sjcl.encrypt()函数了。如果您正在寻找一些AES加密的示例，您可以看到我的详细答案https://stackoverflow.com/a/60504619/6453913。

您也可以使用传统的通用use方法。
