这是我如何使用 phpseclib （有效）：

<?php
include('Crypt/RSA.php');

$rsa = new Crypt_RSA();
$rsa->setPassword('password');
$result = $rsa->loadKey('-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: DES-EDE3-CBC,E3B1C06E0D0C2633

echo $result ? 'true' : 'false';
?>

但是，出于比较目的，我正在尝试使用 OpenSSL 来进行。这是我的代码：

<?php
$pkey = openssl_pkey_get_private('-----BEGIN RSA PRIVATE KEY-----

-----END RSA PRIVATE KEY-----', 'password');
if ($pkey === false) exit('FAILURE');
openssl_pkey_export($pkey, $out_key_file);
echo $out_key_file;
?>

唯一的问题：代码过早地死掉，回显失败。IE。openssl_pkey_get_private() 没有加载密钥。openssl_error_string 说“错误：0906D066：PEM 例程：PEM_read_bio:bad end line”。

有任何想法吗？

我不确定这里发生了什么；我试过你的代码，它给出了同样的问题，所以我自己生成了一个密钥：

openssl genrsa -des3 -out des3.rsa

然后将内容复制到此脚本中：

$out_key_file = 'des3nopass.rsa';

$key = <<<EOS
-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: DES-EDE3-CBC,5F2FDB4C8F710F92

EOS;

$pkey = openssl_pkey_get_private($key, 'password');
if ($pkey === false) {
        die(openssl_error_string());
}

openssl_pkey_export($pkey, $out_key_file);
echo "Wrote to $out_key_file\n";

这对我来说很好。

更新

我也尝试使用openssl命令行执行此操作，使用您的密钥：

openssl rsa -in des3big.rsa -out des3bignopass.rsa
unable to load Private Key
14179:error:0906D066:PEM routines:PEM_read_bio:bad end line:pem_lib.c:746:

OpenSSL 似乎也有问题，所以它不是 PHP。

原来你的行太长了（它们应该是 64 个字符宽）：

通过查看错误原因可能会找到更多信息：

if ($pkey === false) {
  echo openssl_error_string();
  exit('FAILURE');
}

编辑：鉴于错误“PEM_read_bio:bad end line”，这里是触发的 OpenSSL 源部分：

[...]
if ((strncmp(buf,"-----END ",9) != 0) ||
        (strncmp(nameB->data,&(buf[9]),i) != 0) ||
        (strncmp(&(buf[9+i]),"-----\n",6) != 0)) {

        PEMerr(PEM_F_PEM_READ_BIO,PEM_R_BAD_END_LINE);
        goto err;
        }
[...]

查看您的代码，我怀疑您需要在私钥字符串的末尾附加一个换行符。
