【PHP】RSA非对称加密解密 PHP服务端与客户端交互或者提供开放API时，通常需要对敏感的数据进行加密，这时候rsa非对称加密就能派上用处了。举个通俗易懂的例子，假设我们再登录一个网站，发送账号和密码，请求被拦截了。密码没加密，那攻击者就直接拿到了密码，这是最搓的。密码加密了，是不可逆加密，那攻击者只需要模拟那个请求即可登录。密码加密了，是可逆加密，其中携带有时间等参数，后台可以根据时间等参数来判断是否有效，但因为是在前端加密，其加密方式也能在代码中找到，找到加密方式就可以得出解密方式。但是如果我们使用非对称加密就可以避免以上问题。非对称加密算法需要两个密钥来进行加密和解密，这两个秘钥是公开密钥（public key，简称公钥）和私有密钥（private key，简称私钥）。工作过程如下，甲乙之间使用非对称加密的方式完成了重要信息的安全传输。乙方生成一对密钥（公钥和私钥）并将公钥向其它方公开。得到该公钥的甲方使用该密钥对机密信息进行加密后再发送给乙方。乙方再用自己保存的另一把专用密钥（私钥）对加密后的信息进行解密。乙方只能用其专用密钥（私钥）解密由对应的公钥加密后的信息。在传输过程中，即使攻击者截获了传输的密文，并得到了乙的公钥，也无法破解密文，因为只有乙的私钥才能解密密文。同样，如果乙要回复加密信息给甲，那么需要甲先公布甲的公钥给乙用于加密，甲自己保存甲的私钥用于解密。在非对称加密中使用的主要算法有：RSA、Elgamal、背包算法、Rabin、D-H、ECC（椭圆曲线加密算法）等。下面我们通过一个例子来说明如何用PHP来实现RSA的加密解密。<?php class Rsa { public $privateKey = ''; public $publicKey = ''; public function __construct() { $resource = openssl_pkey_new(); openssl_pkey_export($resource, $this->privateKey); $detail = openssl_pkey_get_details($resource); $this->publicKey = $detail['key']; } public function publicEncrypt($data, $publicKey) { openssl_public_encrypt($data, $encrypted, $publicKey); return $encrypted; } public function publicDecrypt($data, $publicKey) { openssl_public_decrypt($data, $decrypted, $publicKey); return $decrypted; } public function privateEncrypt($data, $privateKey) { openssl_private_encrypt($data, $encrypted, $privateKey); return $encrypted; } public function privateDecrypt($data, $privateKey) { openssl_private_decrypt($data, $decrypted, $privateKey); return $decrypted; } } $rsa = new Rsa(); echo "公钥：\n", $rsa->publicKey, "\n"; echo "私钥：\n", $rsa->privateKey, "\n"; // 使用公钥加密 $str = $rsa->publicEncrypt('hello', $rsa->publicKey); // 这里使用base64是为了不出现乱码，默认加密出来的值有乱码 $str = base64_encode($str); echo "公钥加密（base64处理过）：\n", $str, "\n"; $str = base64_decode($str); $pubstr = $rsa->publicDecrypt($str, $rsa->publicKey); echo "公钥解密：\n", $pubstr, "\n"; $privstr = $rsa->privateDecrypt($str, $rsa->privateKey); echo "私钥解密：\n", $privstr, "\n"; // 使用私钥加密 $str = $rsa->privateEncrypt('world', $rsa->privateKey); // 这里使用base64是为了不出现乱码，默认加密出来的值有乱码 $str = base64_encode($str); echo "私钥加密（base64处理过）：\n", $str, "\n"; $str = base64_decode($str); $pubstr = $rsa->publicDecrypt($str, $rsa->publicKey); echo "公钥解密：\n", $pubstr, "\n"; $privstr = $rsa->privateDecrypt($str, $rsa->privateKey); echo "私钥解密：\n", $privstr, "\n"; 大家执行一下可以看到公钥加密的数据，只有私钥能解密，反之亦然，私钥加密的数据只有公钥能解码。这是PHP端的实现，可用在第三方跟平台之间的数据传输，但如果是前端传到后端该怎么办呢，搜索了一下，发现了这个库https://github.com/travist/jsencrypt使用jsencrypt加密解密的例子如下：<!DOCTYPE html> <html> <head> <title>JSEncrypt Example</title> <base id="basetag" href="/jsencrypt-2.3.0/"> <meta http-equiv="Content-Type" content="text/html;

【Typecho】Typecho 防黑安全加固 删除安装文件成功安装后删除 install.php 文件、install/ 文件夹。修改后台地址把 admin 修改为黑客猜不到的名字，例如 pipixia，防止黑客穷举密码。修改`admin`文件夹名称修改 admin 文件夹名称为你喜欢的名称，例如 pipixia修改配置文件以适配修改后的`admin`路径修改 config.inc.php修改为以下代码，我就当修改为 pipixia 了。/** 后台路径(相对路径) */ define('__TYPECHO_ADMIN_DIR__', '/pipixia/');好了。现在你可以访问你的域名/pipixia/ 了。这就是你的新的后台地址，原来的你的域名/admin/ 已经不能访问了。屏蔽 usr、var 目录下 php 文件的访问屏蔽 usr、var 目录下 php 文件的访问可以阻止黑客访问到他上传的 php木马。我们利用 Rewrite 伪静态机制来做。我这里以 Apache 服务器为例，大部分虚拟主机都是 Apache。LiteSpeed Web Server 也使用的是 Apache 的规则。我们同时屏蔽 config.inc.php 和.htaccess 的访问。屏蔽原理就是把要屏蔽的请求重定向到首页文件，首页文件会当成文章名来解析，没有同名文章就会返回 404 未找到。所以就算黑客上传了木马也只会得到 404 未找到的响应。文件名：.htaccess<IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php [E=PATH_INFO:$1] RewriteRule (var|usr)(.+ph*)$ index.php [E=PATH_INFO:$1] RewriteRule (config.inc.php|.htaccess)$ index.php [L,E=PATH_INFO:$1] </IfModule>新建.htaccess 文件添加以上内容，上传到你 typecho 博客的根目录就可以了。Nginx if (!-e $request_filename) { rewrite ^(.*)$ /index.php$1; } rewrite /(var|usr)(.+ph*)$ /index.php; rewrite /(config.inc.php|.htaccess)$ /index.php last;

【redis】PHP Redis扩展无法加载的问题解决方法 问题安装命令pecl install redis安装之后，出现报错：PHP Warning: PHP Startup: Unable to load dynamic library 'redis.so' (tried: /usr/lib64/php/modules/redis.so (/usr/lib64/php/modules/redis.so: undefined symbol: php_json_decode_ex), /usr/lib64/php/modules/redis.so.so (/usr/ lib64/php/modules/redis.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0 解决办法1 配置 php.ini在php.ini中一定要配置extension_dir和extension，如：extension_dir = "/usr/lib64/php/modules/" extension=redis.so2.配置redis.ini# 在/etc/php.d/目录中创建redis.ini文件 vim redis.ini # 文件中添加： extension=redis.so3.重启php-fpm即可systemctl restart php-fpm
