本文实例讲述了PHP7.1实现的AES与RSA加密操作。分享给大家供大家参考，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";
?>

用openssl生成rsa密钥对(私钥/公钥):

openssl genrsa -out rsa_private_key.pem 2048
openssl rsa -pubout -in rsa_private_key.pem -out rsa_public_key.pem

RSA:

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