我看到了这段代码:
<?php
class MyEncryption
{
public $pubkey = '...public key here...';
public $privkey = '...private key here...';
public function encrypt($data)
{
if (openssl_public_encrypt($data, $encrypted, $this->pubkey))
$data = base64_encode($encrypted);
else
throw new Exception('Unable to encrypt data. Perhaps it is bigger than the key size?');
return $data;
}
public function decrypt($data)
{
if (openssl_private_decrypt(base64_decode($data), $decrypted, $this->privkey))
$data = $decrypted;
else
$data = '';
return $data;
}
}
?>
什么是 public_key 的样本?什么样的公钥应该放在 $pubkey 上?它应该是base_64编码还是不?如何生成一个?
我补充说:
$privKey = openssl_pkey_new();
我得到的只是 $privKey==false
