PHP7.1开发AES和RSA加密操作示例

该示例描述了AES和RSA加密操作的实现。分享给大家参考，具体如下：

AES：

<?php
header('Content-Type: text/plain;charset=utf-8');
$data = 'phpbest';
$key = 'oScGU3fj8m/tDCyvsbEhwI91M1FcwvQqWuFpPoDHlFk='; //echo base64_encode(openssl_random_pseudo_bytes(32));
$iv = 'w2wJCnctEG09danPPI7SxQ=='; //echo base64_encode(openssl_random_pseudo_bytes(16));
echo '内容: '.$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";
?>

使用openssl生成RSA密钥对（私钥/公钥）：

openssl genrsa -out  2048
openssl rsa -pubout -in  -out 

RSA：

<?php
header('Content-Type: text/plain;charset=utf-8');
$data = 'phpbest';
echo '原始内容: '.$data."\n";
openssl_public_encrypt($data, $encrypted, file_get_contents(dirname(__FILE__).'/'));
echo '公钥加密: '.base64_encode($encrypted)."\n";
$encrypted = base64_decode('nMD7Yrx37U5AZRpXukingESUNYiSUHWThekrmRA0oD0=');
openssl_private_decrypt($encrypted, $decrypted, file_get_contents(dirname(__FILE__).'/'));
echo '私钥解密: '.$decrypted."\n";
?>
