# RSAForPostman

## usage
you can skip following setting steps, and using example code(pre-script) directly to test a RSA encrypt (see how to use it)
## reference
this project is based on [forge Project](https://github.com/digitalbazaar/forge)
## how to build
First you need to install node and git on your pc.
### clone forge and install
```
git clone https://github.com/digitalbazaar/forge.git
cd /path/to/your/dir
npm install
```
### modify configure
modify`webpack.config.js`, replace `umd` with `var`
```javascript
  const bundle = Object.assign({}, common, {
    output: {
      path: path.join(__dirname, 'dist'),
      filename: info.filenameBase + '.js',
      library: info.library || '[name]',
      libraryTarget: info.libraryTarget || 'var'
    }
  });
  if(info.library === null) {
    delete bundle.output.library;
  }
  if(info.libraryTarget === null) {
    delete bundle.output.libraryTarget;
  }

  // optimized and minified bundle
  const minify = Object.assign({}, common, {
    output: {
      path: path.join(__dirname, 'dist'),
      filename: info.filenameBase + '.min.js',
      library: info.library || '[name]',
      libraryTarget: info.libraryTarget || 'var'
    },
    devtool: 'cheap-module-source-map',
    plugins: [
      new webpack.optimize.UglifyJsPlugin({
        sourceMap: true,
        compress: {
          warnings: true
        },
        output: {
          comments: false
        }
        //beautify: true
      })
    ]
  });
```
### repack
```
npm run build
```
then  in `dist` folder, we'll find a file named `forge.js`, that's what we need.
## how to use it
because Postman can not load js file from local disk, so we put `forge.js` on a web server(**url on github seems not work, a local server may works or add a varible `forgeJS` manully**).

**EDIT: using github raw format works, so you guys can using this example directly**

### pre-script
```
//download forgeJS from web and set varible

if (!pm.globals.has("forgeJS")) {
    pm.sendRequest("http://10.52.16.143/logs/forge.js", function (err, res) {
        if (err) {
            console.log(err);
        } else {
            pm.globals.set("forgeJS", res.text());
        }
    })
} else {

    eval(pm.globals.get("forgeJS"))

    const public_key = '-----BEGIN PUBLIC KEY-----\n' +

    //encrypt text "plaintext"
    var publicKey = forge.pki.publicKeyFromPem(public_key);
    var encryptedText = forge.util.encode64(publicKey.encrypt("plaintext", 'RSA-OAEP', {
        md: forge.md.sha1.create(),
        mgf1: {
            md: forge.md.sha1.create()
        }
    }));
    console.log("encrypted text:" + encryptedText);

    // decrypt text
    var privateKey = forge.pki.privateKeyFromPem(private_key);
    var decryptedText = privateKey.decrypt(forge.util.decode64(encryptedText), 'RSA-OAEP', {
        md: forge.md.sha1.create(),
        mgf1: {
            md: forge.md.sha1.create()
        }
    });

    console.log("dectypted text:" + decryptedText);


}
```
you can use rsa encrypt in postman now!

## something else
### about web server
if you don't want to use a web server, you an simply create a globle varible named `forgeJS` and copy content in `forge.js` to the value(**postman may be very slow because the file is big**)
### how to delete the varible
because of `forgeJS` varible, it may be very diffcuilt to edit other varible in postman, to solve this, you can delete the `forgeJS` varible
```
pm.globals.unset("forgeJS");
```

### ps
this thing is a temporary solution, we all hope postman can support RSA encrypt oneday officially.
