如何在Spring Boot中配置数据库密码加密？ · alibaba/druid Wiki · GitHub

使用ConfigFilter · alibaba/druid Wiki · GitHub

巧用Druid数据源实现数据库连接密码的加密解密功能

import com.alibaba.druid.filter.config.ConfigTools;

public class Testttt {
    public static void main(String[] args) throws Exception {
        String password = "123456";
        System.out.println("明文密码: " + password);
        String[] keyPair = ConfigTools.genKeyPair(512);
        //私钥
        String privateKey = keyPair[0];
        System.out.println("privateKey:" + privateKey);
        //公钥
        String publicKey = keyPair[1];
        System.out.println("publicKey:" + publicKey);
        //用私钥加密后的密文
        password = ConfigTools.encrypt(privateKey, password);
        System.out.println("password:" + password);

        String decryptPassword = ConfigTools.decrypt(publicKey, password);
        System.out.println("解密后:" + decryptPassword);
    }
}
