php – 从rsa私钥中删除密码

2019-09-25 19:31:43 作者：互联网

这是我用phpseclib做的方法(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

-----END RSA PRIVATE KEY-----');

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

但是,为了进行比较,我正在尝试使用OpenSSL.这是我的代码：

<?php
$pkey = openssl_pkey_get_private('-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: DES-EDE3-CBC,E3B1C06E0D0C2633

-----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：代码过早死亡,回应失败.即. openssl_pkey_get_private()未加载密钥. openssl_error_string表示“错误：0906D066：PEM例程：PEM_read_bio：错误的结束行”.

有任何想法吗？

解决方法:

我不确定这里发生了什么;我已经尝试过你的代码并且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

-----END RSA PRIVATE KEY-----
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:

似乎OpenSSL也存在问题,所以它不是PHP.

原来你的线太长了(它们应该是64个字符宽)：
