开发银行或海关的项目经常遇到加密解密的问题

一般客户会提供两个文件
.pfx 结尾的（公钥加私钥文件）
.cer 结尾的文件 （包含公钥文件）

私钥一般都是pfx格式(私钥用来加密生成签名发送报文)
公钥是cer格式（公钥用来验证返回报文里的签名）。
但是php里openssl只能用pem格式,需要把这两个文件转化成pem的：

一、PHP的方式转化

//filePath为pfx文件路径
function signfrompfx($strData, $filePath, $keyPass)
{
    if (!file_exists($filePath)) {
        return false;
    }
    $pkcs12 = file_get_contents($filePath);
    if (openssl_pkcs12_read($pkcs12, $certs, $keyPass)) {
        $privateKey = $certs['pkey'];
        $publicKey = $certs['cert'];
        $signedMsg = "";
        if (openssl_sign($strData, $signedMsg, $privateKey)) {
            $signedMsg = bin2hex($signedMsg);//这个看情况。有些不需要转换成16进制，有些需要base64编码。看各个接口
            return $signedMsg;
        } else {
            return '';
        }
    } else {
        return '0';
    }
}

公钥cer转pem（即x.509证书dem格式转换为pem）

function verifyReturn($data,$signature,$filePath){
    /**
     * filePath为crt,cert文件路径。x.509证书
     * cer to dem， Convert .cer to .pem, cURL uses .pem
     */
    $certificateCAcerContent = file_get_contents($filePath);
    $certificateCApemContent =
        '-----BEGIN CERTIFICATE-----'.PHP_EOL
        .chunk_split(base64_encode($certificateCAcerContent), 64, PHP_EOL)
        .'-----END CERTIFICATE-----'.PHP_EOL;

    $pubkeyid = openssl_get_publickey($certificateCApemContent);

    $len = strlen($signature);
    $signature= pack("H" . $len, $signature); //Php-16进制转换为2进制,看情况。有些接口不需要，有些需要base64解码

    $data=str_replace('<?xml version=\"1.0\" encoding=\"GBK\"?>', '<?xml version="1.0" encoding="GBK"?>', $data);//这个看情况。
    // state whether signature is okay or not
    return openssl_verify($data, $signature, $pubkeyid);
}

二、openssl命令转化

openssl x509 -inform der -in pub.cer -out pub.pem

三、附上截图

PHP扩展gmp被加载两次，报错如下：

PHP Warning: Module "gmp" is already loaded in Unknown on line 0

解决办法：

Not all PHP modules are loaded as separate modules and are part of the
PHP base binary. In this case the module is loaded without a separate
load statement/configuration. If in addition a separate configuration
file exists, e.g. /etc/php7/fpm/conf.d/gmp.ini, the web server tries
to load the module twice which can cause these kind of messages.

//打开.ini配置文件，将下面这行注销即可；
extension=gmp.so

原因：

是因为.ini文件底部又加载了一次，如下：

extension =  /www/server/php/80/lib/php/extensions/no-debug-non-zts-20200930/gmp.so

步骤一：

先检测本机是否有gmp扩展在mamp下，命令如下：

/Applications/MAMP/bin/php/php8.0.8/bin/php -i | grep gmp

如果没有此扩展，此时什么也不会出现，如果已经成功安装了扩展，将会出现如下所示的提示：

PWD => /Applications/MAMP/bin/php/php8.0.8/include/php/ext/gmp
$_SERVER['PWD'] =>
/Applications/MAMP/bin/php/php8.0.8/include/php/ext/gmp $_ENV['PWD']
=> /Applications/MAMP/bin/php/php8.0.8/include/php/ext/gmp

步骤二：

到php官网下载其源码包php-8.0.8.tar.gz。
https://www.php.net/releases/

注意：一定要与你的现在版本一致辞，必须，必须，必须！

可以下载到任意目录，下载完成以后，解压。找到目录.

步骤三：

将目录/Users/liziyu/Downloads/php-8.0.8/ext/，将gmp目录整拷贝到/Applications/MAMP/bin/php/php8.0.8/include/php/ext目录下，如图：

步骤四：

同时进入该目录下：

cd /Applications/MAMP/bin/php/php8.0.8/include/php/ext/gmp

执行命令：

/Applications/MAMP/bin/php/php8.0.8/bin/phpize

然后执行：

./configure --with-php-config=/Applications/MAMP/bin/php/php8.0.8/bin/php-config

再执行：

make

最后：

make install

当出现如下图所示的提示时说明已经安装成功了。
此时重启php，然后执行

php -m 

成功的话会出现如下图的提示：

如果还没有此提示的话，则进入php的配置文件ini去修改，增加下面一行代码：

extension=gmp.so

再重启php查看。即可

这几天和业务方有个签名验签的的需求，对方使用Java对业务数据进行签名，我方使用PHP验签，使用SHA256withRSA算法签名验签，PHP和Java单独签名和验签都没问题，但是由Java签名的数据请求到PHP端时一直验签不通过。
分别对比了Java和PHP生成的待验签字符串和生成的签名，都是一致的，同时也确认过私钥和公钥是一对，但是一到PHP的验签方法openssl_verify()时就是通不过，是在不知道原因出在哪。请求大神们帮忙看看是什么原因，万分感激。

$iv = 'bbbbbbbbbbbbbbbb'; //16位，这个需要与前端吻合

第三部分：引用

微信小程序端引用，比如首页index.js用它。

const encrypt = require('../../utils/aesUtil');
console.log(encrypt.AESEncrypt('hello md5 你好 _-% % &123'))
console.log(encrypt.AESDecrypt('1OloInqltdND24HK7GuecEtkn06kX0h4jPDVRHMGpe8='))
//结果：
//1OloInqltdND24HK7GuecEtkn06kX0h4jPDVRHMGpe8=
//hello md5 你好 _-% % &123

php侧解决办法：

echo md5(rawurlencode('wef中 321fw_@f13we fwe'));

js侧解决办法：

console.log(md5(encodeURIComponent('wef中 321fw_@f13we fwe')));

这样无论是特殊字符、空格、中文都一致了。
