嗨，我正在构建 REST 服务并计划消除从该项目（目前使用 PHP 编写的 REST 服务器）开发客户端和服务器的语言限制。

为了安全起见，我正在验证他们的哈希码以及他们的客户端应用程序签名。目前哈希是成功的，但对于签名它总是失败。

每个客户端都有自己的私钥，在服务器上我们将有他们的公钥来验证签名，每个对服务器的请求都会发送一个签名。如果客户端是 Web 服务器，则所有用户只有一个私钥。如果客户端是本机应用程序 (C#)，则每个已安装的客户端应用程序都将拥有其唯一的私钥。

PHP 客户端到 PHP REST 服务器 -> 计算哈希正常，验证客户端签名正常 C# 客户端 (winapp) 到 PHP REST 服务器 -> 计算哈希正常，验证客户端签名失败

将来我想尝试使用 JAVA，反之亦然。

我使用简单的方法来创建自签名证书

openssl genrsa -des3 -out netclient.key 2048
openssl req -new -x509 -key netclient.key -out netclient.crt
openssl pkcs12 -export -inkey netclient.key -in netclient.crt -out netclient.p12

这是我使用 C# 对数据进行签名的代码

public static string (string Base64EncryptedData ) {
X509Certificate2 my;
my = new X509Certificate2("cert/netclient.p12", "abcdefg", X509KeyStorageFlags.Exportable | X509KeyStorageFlags.PersistKeySet);

RSACryptoServiceProvider csp = null;

csp = (RSACryptoServiceProvider)my.PrivateKey;

SHA1Managed sha1 = new SHA1Managed();
UnicodeEncoding encoding = new UnicodeEncoding();
byte[] data = encoding.GetBytes(Base64EncryptedData);
byte[] hash = sha1.ComputeHash(data);

return Convert.ToBase64String(csp.SignHash(hash, CryptoConfig.MapNameToOID("SHA1"))); 
}

它返回一个签名（base64），我使用 GET 方法将其发送到 PHP REST 服务器。在 PHP 服务器上，我重新计算哈希并验证，但它从不返回 1。目前我手动将所有密钥复制到服务器。

set_include_path(get_include_path() . PATH_SEPARATOR ."lib");
include("Crypt/RSA.php");

$p12cert = array();
$fp=fopen("cert/netclient.p12","r");
$priv_key=fread($fp,8192);
fclose($fp);
openssl_pkcs12_read($priv_key, $p12cert, "abcdefg");

//try using the phpseclib library from http://phpseclib.sourceforge.net
//req() will get all the $_POST, $_GET data req("signature") = $_GET["signature"];
//$hash_request is an base64_encode string same exact value as the one in C#
$rsa = new Crypt_RSA();
$rsa->setHash("sha1");
$rsa->setSignatureMode(CRYPT_RSA_SIGNATURE_PKCS1);
$rsa->loadKey($p12cert["cert"]);
$verified_phpseclib = $rsa->verify($hash_request, base64_decode(req("signature"))) ? "verified" : "diff";

//try using php built in openssl 
$verified_builtin = openssl_verify($hash_request, base64_decode(req('signature')), $p12cert["cert");

非结果返回“已验证”或“1”

可能是因为当 C# 对数据进行签名时，数据的格式是 byte[] 吗？还是有其他原因？

我在 linux php 中运行所有代码 - 使用 apache2 c# - 使用 monodevelop

这是我使用 openssl_pkcs12_read 阅读后的 pk12 数组，您可以在此处下载

试试这个：

<?php
set_include_path(get_include_path() . PATH_SEPARATOR ."lib");
include('File/X509.php');

$p12cert = array();
$fp=fopen("cert/netclient.p12","r");
$priv_key=fread($fp,8192);
fclose($fp);
openssl_pkcs12_read($priv_key, $p12cert, "abcdefg");

$x509 = new File_X509();
$x509->loadX509($p12cert["cert"]);
$pubkey = $x509->getPublicKey();
$pubkey->setSignatureMode(CRYPT_RSA_SIGNATURE_PKCS1);
$verified_phpseclib = $pubkey->verify($hash_request, base64_decode(req("signature"))) ? "verified" : "diff";
