}
可以看出秘钥是16进制的byte数组先用上面的 bytesToHexFun3 方法获取字符串
得到的就是秘钥就是 0b13e7b2510d75c24edd4b512436a8280b13e2b2310d75c1运行main方法对123456就行加密得到aKZ47zrp0I再解密2. 相同的php加密和解密方法
?php
$str 0c13e7b2510d75c34fdd4e512436a6280b13e2b8310d75c1;
$string des_ecb_encrypt(123456,Hex2String($str));
echo 加密结果,$string;echo 换行;;
echo 解密结果,des_ecb_decrypt($string,Hex2String($str));function Hex2String($hex){$string;for ($i0; $i strlen($hex)-1; $i2){$string . chr(hexdec($hex[$i].$hex[$i1]));}return $string;
}
function des_ecb_encrypt($data, $key){return openssl_encrypt ($data, des-ecb, $key);
}
function des_ecb_decrypt ($data, $key){return openssl_decrypt ($data, des-ecb, $key);
}
?
$str 就是上面java加密解密的key先转换成16进制byte数组再进行加密解密。
主要调用的是openssl的des加密方法。
还有别的加密模式可以参考这篇 https://www.36nu.com/post/252
如果你没安装wampserver的话安装可以参考这篇。https://blog.csdn.net/Angry_Mills/article/details/80790522
或者你懒得安装也可以在线调试php代码。

调试结果如图
