这是我的代码.
X509Certificate pXCert = new X509Certificate2(@"keyStore.p12", "password");
RSACryptoServiceProvider csp = (RSACryptoServiceProvider)pXCert.PrivateKey;
string id = CryptoConfig.MapNameToOID("SHA256");
return csp.SignData(File.ReadAllBytes(filePath), id);
在最后一行我得到了异常:
On the last line I'm getting the exception:
System.Security.Cryptography.CryptographicException "指定的算法无效."
System.Security.Cryptography.CryptographicException "Invalid algorithm specified."
我做错了什么?
更新:
id = 2.16.840.1.101.3.4.2.1
id = 2.16.840.1.101.3.4.2.1
.NET 代码或您提供的 CSP 代码没有问题.
There is no issue with .NET code or the CSP code you provided.
您的问题是 CSP 不支持 SHA 256.您可以获取更多信息 这里
Your problem is that CSP just doesn’t support SHA 256. You can get further information here
