I am trying to create X509Certificate2 from string. Let me show an example:
string keyBase64String = Convert.ToBase64String(file.PKCS7);
var cert = new X509Certificate2(Convert.FromBase64String(keyBase64String));
and keyBase64String has a such content: "MIIF0QYJKoZI ........hvcNAQcCoIIFwjCCBb4CA0="
and file.PKCS7 is byte array which I downloaded from database.
I've got the following exception when creating X509Certificate2:
Cannot find the requested object
And the stack trace:
"Cannot find requested object" X509Certificate2 Exception "Cannot find requested object"} at System.Security.Cryptography.CryptographicException.ThrowCryptographicException(Int32 hr) at System.Security.Cryptography.X509Certificates.X509Utils._QueryCertBlobType(Byte[] rawData) at System.Security.Cryptography.X509Certificates.X509Certificate.LoadCertificateFromBlob(Byte[] rawData, Object password, X509KeyStorageFlags keyStorageFlags) at System.Security.Cryptography.X509Certificates.X509Certificate2..ctor(Byte[] rawData) at WebApp.SoupController.d__7.MoveNext() in D:\Projects\WebApp\Controllers\SoupController.cs:line 118
Please, say me what I am doing wrong. Any help would be greatly appreciated!
