【分享】云函数解析抖音开放平台 用户手机号示例

解密抖音用户手机号/字节跳动小程序ACE解密示例
需要引入 crypto; // nodejs 自带包直接使用
亲测可用

 let encryptedMobile = 获得的加密手机号;  
 let keyStr = 你的client_secret;  

 const algorithm = 'aes-256-cbc';  
 const ivStr = keyStr.substr(0, 16);  
 const keyByte = Buffer.from(keyStr)  
 const ivByte = Buffer.from(ivStr)  
 const encryptedText = Buffer.from(encryptedMobile,"base64")  

 try {  
     const decipher = crypto.createDecipheriv('aes-256-cbc', keyByte, ivByte)  
     decipher.setAutoPadding(true);  
     var phone_info = decipher.update(encryptedText, 'binary', 'utf8');  
     phone_info += decipher.final('utf8');  
 }catch(err){  
     console.log('err: ', err)  
}  
console.log('phone_info: ', phone_info)
