Question

我有一个MYSQL数据库，用于存储IMAP帐户的加密凭据。密码字段是推荐的BLOB。

        $encrypter = new TripleDES(CRYPT_DES_MODE_ECB);
        $encrypter->setKey($this->container->getParameter('secure_token'));
        $encrytped_pw = $encrypter->encrypt("MYPASSWORD");

        $mailbox->setUrl('{outlook.office365.com:993/imap/ssl}');
        $mailbox->setUsername('user@domain.tld');
        $mailbox->setPassword(base64_decode($encrytped_pw));
        $em->persist($mailbox);
        $em->flush();

不幸的是我无法使用此解密此字段：

    $mailboxPw = $this->getUser()->getMailbox()->getPassword();

    $decrypter = new TripleDES(CRYPT_DES_MODE_ECB);
    $decrypter->setKey($this->container->getParameter('secure_token'));
    $decrytped_pw = $decrypter->decrypt(base64_encode($mailboxPw));

因为它给了我

Warning: base64_encode() expects parameter 1 to be string, resource given

我找不到将blob资源转换为字符串的方法，有没有其他方法可以实现我想要的呢？

任何暗示赞赏

可以使用 stream_get_contents 来读取资源：

$mailboxPwResource = $this->getUser()->getMailbox()->getPassword();
$mailboxPw = stream_get_contents($mailboxPwResource);

$decrypter = new TripleDES(CRYPT_DES_MODE_ECB);
$decrypter->setKey($this->container->getParameter('secure_token'));
$decrytped_pw = $decrypter->decrypt(base64_encode($mailboxPw));

在PHP中读取BLOB到字符串（Symfony2）
