PHP7 0 32安裝 mcrypt 擴充套件

求php7.1 加密函式mcrypt_module_open()替換方案

php mcrypt 擴充套件模組安裝及使用

php7.1中使用openssl替換mcrypt

linux版openssl生成rsa公私鑰

php 7.2 安裝 mcrypt 擴充套件

1.yum 安裝依賴包

#yum install libmcrypt libmcrypt-devel mcrypt mhash

#wget  

#tar xf mcrypt-1.0.1.tgz
#cd mcrypt-1.0.1

#/usr/local/php/bin/phpize

#./configure --with-php-config=/usr/local/php/bin/php-config && make && make install

#extension=mcrypt.so

#/etc/init.d/php-fpm restart

#service php-fpm restart

#service httpd restart

下面看看用openssl實現對稱加密aes和非對稱加密rsa.

aes:

<?php
header('content-type: text/plain;charset=utf-8');
$data = 'phpbest';
$key = 'oscgu3fj8m/tdcyvsbehwi91m1fcwvqqwufppodhlfk='; //echo base64_encode(openssl_random_pseudo_bytes(32));
$iv = 'w2wjcncteg09danppi7sxq=='; //echo base64_encode(openssl_random_pseudo_bytes(16));
echo '內容: '.$data."\n";
$encrypted = openssl_encrypt($data, 'aes-256-cbc', base64_decode($key), openssl_raw_data, base64_decode($iv));
echo '加密: '.base64_encode($encrypted)."\n";
$encrypted = base64_decode('to3qffvgjnm84kbkg1plza==');
$decrypted = openssl_decrypt($encrypted, 'aes-256-cbc', base64_decode($key), openssl_raw_data, base64_decode($iv));
echo '解密: '.$decrypted."\n";
?>
rsa:
用openssl生成rsa金鑰對(私鑰/公鑰):
openssl genrsa -out rsa_private_key.pem 1024
openssl rsa -pubout -in rsa_private_key.pem -out rsa_public_key.pem
<?php
header('content-type: text/plain;charset=utf-8');
$data = 'phpbest';
echo '原始內容: '.$data."\n";
openssl_public_encrypt($data, $encrypted, file_get_contents(dirname(__file__).'/rsa_public_key.pem'));
echo '公鑰加密: '.base64_encode($encrypted)."\n";
$encrypted = base64_decode('nmd7yrx37u5azrpxukingesunyisuhwthekrmra0od0=');
openssl_private_decrypt($encrypted, $decrypted, file_get_contents(dirname(__file__).'/rsa_private_key.pem'));
echo '私鑰解密: '.$decrypted."\n";
?>

#openssl version -v  //檢視openssl的版本

//生成私鑰 *.pem檔案放在當前資料夾下
#openssl genrsa -out rsa_private_key.pem 1024 
//對私鑰進行pkcs#8編碼
# openssl pkcs8 -topk8 -in rsa_private_key.pem -out pkcs8_rsa_private_key.pem -nocrypt 
//根據生成的私鑰生成公鑰
#openssl rsa -in rsa_private_key.pem -out rsa_public_key.pem -pubout
