importKey/exportKey/generateKey

介绍

该接口用于密钥导入，导出、以及随机生成，详细定义及用法参见MDN官方文档importKey、exportKey、generateKey。

算法

• RSA
• HMAC
• AES
• ECDSA

示例

async function handle() {
  var algorithm = {name: "HMAC", hash: {name: "SHA-512"}};
  var key = await crypto.subtle.generateKey(algorithm, 
      true, ['sign', 'verify']);
  var raw_key = await crypto.subtle.exportKey("Raw", key);
  var import_key = await crypto.subtle.importKey("Raw", raw_key, algorithm, 
      true, ['sign', 'verify']);
}
