Question

我想我已经两次问了这个问题，没有人甚至不愿意这样看。请帮助我，并在忘记问题之前尝试至少考虑一下。所以我正在学习本教程：http://www.stellarwebsolutions.com/en/articles/paypal_button_encryption_php.php当我使用他们的代码并插入所有与我不同的东西时，我运行代码并从paypal“无法解密证书ID”获得错误消息。经过一番研究后，我发现代码中的函数返回“ERROR：Encryption failed”。我认为错误是由以下代码引起的：

$openssl_cmd = "($OPENSSL smime -sign -signer $MY_CERT_FILE -inkey $MY_KEY_FILE " .
                    "-outform der -nodetach -binary < \"_EOF_\n$data\n_EOF_\n\") | " .
                    "$OPENSSL smime -encrypt -des3 -binary -outform pem $PAYPAL_CERT_FILE";

exec($openssl_cmd, $output, $error);

if (!$error) {
    return implode("\n",$output);
} else {
    return "ERROR: encryption failed";
}

有没有办法将此openssl命令转换为openssl_something();来电？我非常感谢任何帮助。这是完整的代码和另一个注释：请不要对主题进行愚蠢的评论，例如问题很糟糕，e.t.c。：

Answer 1

那么，这是我的答案;）您可能遇到safe_mode的问题，这会阻止您的代码执行openssl二进制文件。

openssl命令不起作用，所以我可以使用php openssl函数
