openssl_verify():提供的密钥参数不能强制为.pem文件的公共密钥 [英] openssl_verify(): supplied key param cannot be coerced into a public key for a .pem file

问题描述

当前正在尝试读取.pem公钥以通过openssl对其进行验证.

Currently attempting to read a .pem public key to verify it through openssl.

/**
 * Check whether the signed message sent back by the server is
 * correct or not.
 */
function check($str, $MAC)
{
    $fp = fopen(
        dirname(__FILE__) . '/rsa_public_key.pem',
        'r'
    );

    $cert = fread($fp, 8192);

    fclose($fp);

    $pubkeyid = openssl_get_publickey($cert);

    return openssl_verify($str, $MAC, $pubkeyid);
}

话虽如此，执行脚本后，我收到此错误:

With that said, upon executing my script, I receive this error:

openssl_verify(): supplied key param cannot be coerced into a public key in some/path at line X

最初，我编写了此函数来接受.cer认证.这是所有这些

Originally, I wrote this function to accept .cer certifications. Here's an explanation of the difference between all these different key formats. To my understanding .pem are similar to .cer, however, I could not for the life of me figure out how to allow my script to read my .pem file.

我的问题是-为了使我的功能读取此公钥，我需要做什么?

My question is - what do I need to do in order for my function to read this public key?

在进行一些谷歌搜索时，我尝试使用file_get_contents()到特定路径，但是会收到相同的错误.

Upon some Googling, I have tried using file_get_contents() to a particular path but I would receive the same error.

什么可能导致此错误?

推荐答案

打开此.pem文件后，它们全部放在一行中.看来每一行都需要64个字符的长度，因此我确保每一行都是64行，并且可以成功解析.与.cer无关.

Upon opening this .pem file, it was all in one line. It appears each line requires the length of 64 characters, so I made sure each line was 64 lines, and it successfully parsed. Had nothing to do with .cer.
