<p>首先进入root目录，查看刚刚下载的工作环境<code>node_modules</code><br>

<p>进入路径node_modules，并创建sm2.js文件，验证代码如下：</p>
<pre><code>const { SM2 } = require('gm-crypto')
const { publicKey, privateKey } = SM2.generateKeyPair()
const originalData = '20201307lcy'
const encryptedData = SM2.encrypt(originalData, publicKey, {
inputEncoding: 'utf8',
outputEncoding: 'base64'
})
console.log(encryptedData)
const decryptedData = SM2.decrypt(encryptedData, privateKey, {
inputEncoding: 'base64',
outputEncoding: 'utf8'
})
console.log(decryptedData)
</code></pre>
