php密码加密速度较慢
用户密码加密采用password_hash
先hash时间戳,再用hash后的值跟静态盐跟用户密码hash得到密码,
线上运行发现速度比较慢,最慢一次大约有2000ms,
有什么好的解决方案么?

加盐md5即可, php自带的加密函数不利于跨平台
1.用MD5加密
2.PHP的几个常用加密函数:https://jellybool.com/post/php-encrypt-functions
3.自定义加密 // 百度很多的
4.PHP 标准AES加密算法类 http://www.oschina.net/code/snippet_99277_45148
github 一个php自定义加密的:
`
<code>require_once("xxtea.php"); $str = "Hello World! 你好,中国!"; $key = "1234567890"; $encrypt_data = xxtea_encrypt($str, $key); $decrypt_data = xxtea_decrypt($encrypt_data, $key); if ($str == $decrypt_data) { echo "success!"; } else { echo "fail!"; }</code>
?>`

可以让hash的逻辑在mysql里做,mysql有MD5函数、password函数,可以试试
问题找到了,password_hash会传入三个参数,最后一个参数是一个数组,里面有一个'cost'指定加密迭代次数,默认13即2^13次。将数改小之后速度提升明显。
如果你写个PHP扩展
如果你用Docker部署环境。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
