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。

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
