多年来,无论是在win/IIS还是在Linux上,我一直在我的php应用程序中大量使用mcrypt。尽管我在Linux服务器上运行PHP 5.4.28,但我刚刚在Windows 8.1 IIS框中升级到PHP 5.6.11。并且mcrypt不再起作用。它不会抛出我可以看到的任何错误;就是行不通。这是我的加密功能:

function Encrypt($text){
    global $salt;
    if($text != "")
        return trim(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $salt, $text, MCRYPT_MODE_ECB, mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB), MCRYPT_RAND))));
    else
        return "";
}

这在我的linux服务器上工作正常,但是在我的本地Windows框中返回空白。据我了解,mcrypt内置于Windows的php 5.6中,因此不应摆弄扩展名或ini文件。

我想念什么?

最佳答案

让我们一步一步地看一下您的代码。 (主要是外观/空白更改。)

function Encrypt($text)
{
    global $salt; // Why not make this a second parameter?
    if($text != "") { // An unusual check, for sure
        return trim( // base64_encode doesn't leave whitespace
            base64_encode(
                mcrypt_encrypt(
                    MCRYPT_RIJNDAEL_256, // This is a non-standard variant of the
                                         // Rijndael cipher. You want to use the
                                         // MCRYPT_RIJNDAEL_128 constant if you
                                         // wanted to use AES here.
                    $salt, // This is a key, not a salt!
                    $text,
                    MCRYPT_MODE_ECB, // ECB mode is the worst mode to use for
                                     // cryptography. Among other reasons, it
                                     // doesn't even use the IV. Search for
                                     // ECB penguins for an idea of why ECB
                                     // mode is such a bad idea.
                    mcrypt_create_iv(
                        mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB),
                        MCRYPT_RAND // You're using ECB mode so this is a waste
                                    // anyway, but you should use
                                    // MCRYPT_DEV_URANDOM instead of MCRYPT_RAND
                    )
                )
            )
        );
    }
    return "";
}

我强烈建议您不要将此功能用于任何用途。这是不安全的。 Don't use ECB mode

此外,unauthenticated encryption is dangerouslibmcrypt is abandonware
