场景:

app开发,对接接口,进行签名sign验证,采用aes加密,最后发现php中生成的sign与java(android)中不一样,尝试了一阵子找到解决方法:


php中aes加解密:


<?php

$str='www.hu-rong.com';

$key='d8b2b7da008e57bd4f4f7b3177415973';

$iv='1234567890123456';//此种模式下iv长度为16

$method='aes-256-cbc';

echo '要加密的字符串:'.$str.'<br/>';

echo 'key:'.$key.'<br/>';

echo 'iv:'.$iv.'<br/>';

echo '模式:'.$method.'<br/>';

echo '加密后的结果是:<br/>';

echo $str_jiami=openssl_encrypt($str, $method, $key, 0, $iv);

echo '<br/>解密后的结果是:';

echo openssl_decrypt($str_jiami, $method,$key,false,$iv);



运行结果:

key:d8b2b7da008e57bd4f4f7b3177415973
iv:1234567890123456
模式:aes-256-cbc
加密后的结果是:
vJOK/SYa068JScpaOrTfeg==
解密后的结果是:www.hu-rong.com

要加密的字符串:www.hu-rong.com



java中加密方法1,遗憾的是这个没有提供解密方法:

https://blog.csdn.net/xiojing825/article/details/78491374


package main.java.com.leon.channel.command;

import javax.crypto.Cipher;

import javax.crypto.spec.IvParameterSpec;

import javax.crypto.spec.SecretKeySpec;

import java.util.Base64;


public class Main {


public static void main(String[] args) {

String data = "my_data";

String passwrod = "my_password";

String iv = "1234567890123456";


try {

String base64Str = java_openssl_encrypt(data, passwrod, iv);

//输出: uD1WB/3VZH+zEObhVxdQvA==

System.out.print(base64Str);


} catch (Exception e) {

e.printStackTrace();

}

}


public static String java_openssl_encrypt(String data, String password, String iv) throws Exception {

byte[] key = new byte[32];

for (int i = 0; i < 32; i++) {

if (i < password.getBytes().length) {

key[i] = password.getBytes()[i];

} else {

key[i] = 0;

}

}


Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");


cipher.init(Cipher.ENCRYPT_MODE, new SecretKeySpec(key, "AES"),

new IvParameterSpec(iv.getBytes()));


String base64Str = Base64.getEncoder().encodeToString(cipher.doFinal(data.getBytes()));



return base64Str;

}


}


java aes加解密方法2:

https://github.com/simplephp/php-java-AES-128-ECB/blob/master/aes.php

此种方法的php代码比较古老,php7.2中报错:

Call to undefined function mcrypt_get_block_size

此时要安装mcrypt扩展:

https://blog.csdn.net/yhb598712254/article/details/80621473

http://pecl.php.net/package/mcrypt/1.0.1


wget http://pecl.php.net/get/mcrypt-1.0.1.tgz

tar zxvf mcrypt-1.1.1.tgz

cd mcrypt-1.0.1

phpize

./configure

make && make install

修改php.ini

重启php-fpm


如果安装mcrypt报错:

编译报错:configure: error: mcrypt.h not found. Please reinstall libmcrypt.

执行:

yum install -y epel-release

yum install -y libmcrypt-devel

两个不能一起安装,因为CentOs6默认的yum源没有 libmcrypt-devel这个包,只能借助epel的yum源,所以先安装epel,再安装libmcrypt。

最后能跑但还是会给出提示,因mcrypt比较古老,已弃用;
