登录密码md5加密

1、引入依赖

	<dependency>
	    <groupId>commons-codec</groupId>
	    <artifactId>commons-codec</artifactId>
	</dependency>
	<dependency>
	    <groupId>org.apache.commons</groupId>
	    <artifactId>commons-lang3</artifactId>
	    <version>3.6</version>
	</dependency>

2、客户端md5加密后服务端MD5加密

import org.apache.commons.codec.digest.DigestUtils;

public class MD5Util {
	
	public static String md5(String src) {
		return DigestUtils.md5Hex(src);
	}
	
	private static final String salt = "qwertyui";
	
	public static String inputPassToFormPass(String inputPass) {
		String str = ""+salt.charAt(0)+salt.charAt(2) + inputPass +salt.charAt(5) + salt.charAt(4);
		System.out.println(str);
		return md5(str);
	}
	
	public static String formPassToDBPass(String formPass, String salt) {
		String str = ""+salt.charAt(0)+salt.charAt(2) + formPass +salt.charAt(5) + salt.charAt(4);
		return md5(str);
	}
	
	public static String inputPassToDbPass(String inputPass, String saltDB) {
		String formPass = inputPassToFormPass(inputPass);
		String dbPass = formPassToDBPass(formPass, saltDB);
		return dbPass;
	}
	
	public static void main(String[] args) {
	System.out.println(formPassToDBPass(inputPassToFormPass("123456"), UUID.randomUUID().toString().replace("-", "");));
	
	}
	
}
