问题描述
我正在尝试在 PHP 中使用 OpenSSL 函数进行 RSA 签名/验证.当我尝试使用我的公钥执行 openssl_verify 时，出现此错误:error:0906D06C:PEMroutines:PEM_read_bio:no start line，但函数本身可以正常工作(如果消息被修改则返回 0，如果完好则返回 1).openssl_sign 工作正常.
I am trying to use OpenSSL function for RSA sign/verify in PHP.
When I try to do openssl_verify using my public key, I am getting this error: error:0906D06C:PEM routines:PEM_read_bio:no start line, but the function itself works correctly (returns 0 if messages was modified, and 1 if intact). openssl_sign works fine.
我该如何解决?
目前，我使用的是由 openssl 生成的公钥:
Currently, I use public key generated by openssl:
define("SC_MSG_PUBLIC", <<<EOD
-----BEGIN PUBLIC KEY-----
MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBALjPcOckMHDVLiUstcRwwx8kF5PzsiEs
rskyndWisbXMLU9BHomXwL7Qg2L91jE+sNSobkzBDF41CbwDiNlofZUCAwEAAQ==
-----END PUBLIC KEY-----
EOD
);
知道为什么会触发此错误，但一切正常吗?
Any ideas why this error triggers, but things works fine?
尝试从私有中生成公钥并使用它，但它似乎完全相同，相同的错误消息:-S
Tried to generate public key out of private, and use it, but it appeared to be exactly the same, same error message :-S
$pkey = openssl_pkey_get_private(SC_MSG_PRIVATE);
$keyDetails = openssl_pkey_get_details($pkey);
file_put_contents('c:publickey', $keyDetails['key']);
此外，我尝试安装所有更新版本(PHP 5.3.1、OpenSSL 1.0.0a) - 结果相同.而且，我在窗户上.
Also, I've tried to install newer versions of everything (PHP 5.3.1, OpenSSL 1.0.0a) - same result. And, I am on windows.
推荐答案
您是否尝试使用包含您的公钥而不是纯公钥的(可能是自签名的)证书调用 openssl_verify()关键?
Have you tried to call openssl_verify() with a (maybe self-signed) certificate containing your public key instead of a pure public key ?
据我所知，一些 PHP OpenSSL 函数不能正确支持裸公钥，尽管尽管出现错误，但它确实验证正确似乎很奇怪.
As far as I know, some PHP OpenSSL functions do not properly support naked public keys although it seems strange that it does verify correctly in spite of the error.
<?php
$private = openssl_pkey_get_private(file_get_contents('private'), 'passphrase');
// This causes the "no start line" error when using a naked public key:
$public = openssl_pkey_get_public(file_get_contents('public')); // <-- this should be cert
echo openssl_error_string()."
";
openssl_sign('Test', $sig, $private);
var_dump(openssl_verify('Test', $sig, $public));
echo openssl_error_string()."
";
?>
在 bash 等 Linux/UNIX shell 中将公钥转换为简单证书的示例(有关更多信息，请参阅 OpenSSL 文档或一些教程):
Example for converting a public key to a simple certificate in a Linux/UNIX shell such as bash (refer to the OpenSSL documentation or some tutorials for more):
# Create certificate request
openssl req -new -days 3600 -key [PRIVATE-KEY-FILE] -out [REQUEST-TMP-FILE]
# Create certificate from request
RANDFILE=[RANDOM-TMP-FILE] openssl x509 -req -in [REQUEST-TMP-FILE] -signkey [PRIVATE-KEY-FILE] -out [CERTIFICATE-OUT-FILE]
这也会创建您之后可能想要删除的临时文件，即 [REQUEST-TMP-FILE] 和 [RANDOM-TMP-FILE].
This will also create temporary files you might want to delete afterwards, namely [REQUEST-TMP-FILE] and [RANDOM-TMP-FILE].
