PHP非对称加密RAS
需要用到:
1、需要用到RAS可以百度搜索RAS在线生成,这里推荐:http://www.bm8.com.cn/webtool/rsa//
2、php扩展php_openssl
3、用到扩展 ，可以具体查看文档：https://www.php.net/manual/zh/book.openssl.php
openssl_private_decrypt — 使用私钥解密数据
openssl_private_encrypt — 使用私钥加密数据
openssl_public_decrypt — 使用公钥解密数据
openssl_public_encrypt — 使用公钥加密数据通过生成获取了私钥与公钥
