我正在尝试通过使用PHPSECLIB（http://phpseclib.sourceforge.net/）来实现RSA 我认识到的PHP页面效果很好，它生成了一个公共密钥和一个私有密钥，并且对明文进行了很好的加密和解密。 关键是$ ciphertex由奇怪的符号组成，无法正确保存到我的MYSQL数据库内的varchar列中。 这是代码
<?php
include 'Crypt/RSA.php';
include 'Crypt/Rijndael.php';
$rsa = new Crypt_RSA();
$keys = $rsa->createKey(2048);
$rsa = new Crypt_RSA();
$rsa->loadKey($keys['publickey']); // public key
echo $keys['publickey'];
echo "\n -----\n";
echo $keys['privatekey'];
echo "\n -----\n";
$plaintext = 'My text';
echo $plaintext;
$ciphertext = $rsa->encrypt($plaintext);
echo $ciphertext;
$rsa = new Crypt_RSA();
$rsa->loadKey($keys['privatekey']); // private key
echo "\n -----\n";
echo $rsa->decrypt($ciphertext); ?>
这是我的私钥示例
