Druid数据库密码加密、解密

数据库密码加密：

1.maven引入druid jar包


    com.alibaba
    druid-spring-boot-starter
    1.1.21

2.打开命令行，进入到druid 的目录，如C:Userschengh97.m2repositorycomalibabadruid1.1.21>

执行指令：java -cp druid-1.0.26.jar com.alibaba.druid.filter.config.ConfigTools 你的密码（示例为123456）：

privateKey:MIIBVgIBADANBgkqhkiG9w0BAQEFAASCAUAwggE8AgEAAkEA0Fu+pHGa4WkEN57Jcgl65FZ+VTRVyK6ElbsC1+VRIy5ihGcSVqN2FS4dI5AQlGRPV0MskQj+n/MoTV0pHKyqawIDAQABAkEAjrXIJioJw0qCsPX5VDpaCfuUHBf0ibe+6C9nCyjuIgFu5+vGaLfpmR7MajoWwlomw9ZBx4QyVmq3foCSIPxxwQIhAOegxR7AOa6YWt9X073FOfd7GPYKwgc9y2IauroUDpNnAiEA5kgskZsTlL9AniY3xzfSvMsSl88bEJlVF2caPZFRMl0CIQCtu4SeoAej0Vq3kqSa/keQPKBoS4Fk9RCLsQjFcS3NmQIhAKQJbZYa/YvL4N/HIZyLq1ZI4em54fGlB/QvwYVx6oERAiAlF2ArHllv+Q5YfqLdgiEpT+eRkkimdvxlpRtjEI2b3w==

publicKey:MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBANBbvqRxmuFpBDeeyXIJeuRWflU0VciuhJW7AtflUSMuYoRnElajdhUuHSOQEJRkT1dDLJEI/p/zKE1dKRysqmsCAwEAAQ==

password:e2iMnDbFDfvIYj+QMbV7x0fuyjcTG6cwCtAXzq2DwDOIHo91IqBjnU9qB89FFf9X5AAJqnFaoRWGhe7qhmYucQ==

3.此时获取到公钥publicKey，私钥privateKey，以及密码password，取publicKey及password填入druid的配置中即可

# mysql
spring.datasource.druid.url=jdbc:mysql://192.168.100.11:3306/education_course?useUnicode=true&characterEncoding=utf-8&useSSL=false
spring.datasource.druid.username=roncoo
spring.datasource.druid.password=e2iMnDbFDfvIYj+QMbV7x0fuyjcTG6cwCtAXzq2DwDOIHo91IqBjnU9qB89FFf9X5AAJqnFaoRWGhe7qhmYucQ==
spring.datasource.druid.publicKey=MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBANBbvqRxmuFpBDeeyXIJeuRWflU0VciuhJW7AtflUSMuYoRnElajdhUuHSOQEJRkT1dDLJEI/p/zKE1dKRysqmsCAwEAAQ==
spring.datasource.druid.filters=config
spring.datasource.druid.connection-properties=config.decrypt=true

数据库密码解密：

得到加密后的密码，和publicKey，利用druid包里的ConfigTools的decrypt方法解密：

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

public class DruidUtil {

	public static void main(String[] args) throws Exception {
		String password = "123456";
		System.out.println(ConfigTools.encrypt(password));
	}

}
