请注意,文档中的 file://path/to/file.pem 表示文件协议+文件路径。在像 OS 一样的UNIX中,类似 file:///rsa_public_pertial_key.pem 的东西。路径字符串中存在 THREE smarsh,而不是两个。不能省略 files:// 。

只要把钥匙放进Var就容易多了

if (!$privateKey = openssl_pkey_get_private($private)) die( Loading Private Key failed );
if (!$publicKey = openssl_pkey_get_public($public)) die( Loading Public Key failed );

我还将包括一个小的编码/编码示例:

$encrypted =   ;
$decrypted =   ;

$plaintext =  This is just some text to encrypt ;

echo  <p>$plaintext =   . $plaintext .  <p> ;

if (!openssl_public_encrypt($plaintext, $encrypted, $publicKey))    die( Failed to encrypt data );

echo  <p>$encrypted =   . $encrypted .  <p> ;

if (!openssl_private_decrypt($encrypted, $decrypted, $privateKey))  die( Failed to decrypt data );

echo  <p>$decrypted =   . $decrypted .  <p> ;

或者如果你能用php生成一个密钥:

$NEW_KEY = openssl_pkey_new(array(
     private_key_bits  => 1024,
     private_key_type  => OPENSSL_KEYTYPE_RSA,
        ));

openssl_pkey_export_to_file($NEW_KEY,  private.key );

$NEW_KEY_DETAILS = openssl_pkey_get_details($NEW_KEY);
file_put_contents( public.key , $NEW_KEY_DETAILS[ key ]);

openssl_free_key($NEW_KEY);

请参见下一个 URL 。

https://www.php.net/manual/en/conflices.openssl-pkey-get-public.php" rel=“不跟随 no follown noreferrer>>https://www.php.net/manual/en/conflicesl-pkey-get-public.php

要缩小问题范围, 请在您的 php 文件和密钥文件 中使用 < em> same 目录, 并尝试此工作代码 。

<强力 > 工作代码

$keyfile="file://".__DIR__.DIRECTORY_SEPARATOR."key.pem"; //absolute path
$key = openssl_pkey_get_private($keyfile);

if ($key === false) {
    var_dump(openssl_error_string());
}else{
    var_dump($key);
}

以下可能是一个问题。

1. Path

遵循路径样式应该有效 。

$keyfile="file:///home/john/php/key.pem"; // unix absoulute path
$keyfile="file://C:\users\john\php\key.pem"; // windows absoulute path
$keyfile="file://".__DIR__.DIRECTORY_SEPARATOR."key.pem"; //absoulute path for unix, windows
$keyfile="file://key.pem"; // relative path, unix, windows, (php,key files in same directory)

$key = openssl_pkey_get_private($keyfile);

如果路径不存在, 错误将会像

“error: 02001002: system library: fopen: 没有这样的文件或目录”

2. <强度 > 网络环境

   检查您对文件夹和密钥文件的网络根权限和网络用户权限 。

   为了减少问题,在php 内建网络服务器总机上而不是WAMP 总机上测试。

>php -S localhost:80

3. Corrupted key file

saved as certain type which include whitespaces. This can occur error like next.

“error: 0906D06C: PEM 常规: PEM_read_bio: no start line”

in my case, key file was saved as UTF-8 with BOM(whitespaces)

< 坚固 > DEBUG 密钥文件 1 - 从 VARIEW < /坚固 > 读取

This code should work. I got key file from http://micmap.org/php-by-example/en/function/openssl_pkey_get_private
