第三个元素signatureValue是BIT STRING类型。值为对tbsCertificate的SM2签名，而按照国密标准本身SM2签名也是ASN1结构，所以从下图可以看出签名的r-s结构。证书的X509结构就介绍完毕，欢迎各位指正。
3)编程的方法创建,.Net提供了X509Certificate2类,该类可以用于创建证书,但只能从RawData中创建,创建后无法修改除FriendlyName以外的任何属性。 我在互联网上找了很久,始终没有找到完全通过程序创建自定义的证书的方法。后来想了一个折中办法,就是用程序调用makecert.exe先生成一个证书,证书的一些参数如Subject,有效期,...
privateKey = RSA.ExportParameters(true); //将要重置的密钥对中的公钥参数覆盖原参数 j = 0; for (i = modulePos; i < modulePos + 128; i++) { certBytes[i] = publicKey.Modulus[j]; j++; } //用新参数重新创建证书 cert = new X509Certificate2(certBytes); 这样一来privateKey就成了新证书...
