System.Security.Cryptography.CryptographicException:密钥在指定状态下无效。
在 System.Security.Cryptography.CryptographicException.ThrowCryptographicException(Int32 hr) 在 System.Security.Cryptography.Utils._ExportKey(SafeKeyHandle hKey, Int32 blobType, Object cspObject) 在 System.Security.Cryptography.RSACryptoServiceProvider.ExportParameters(Boolean includePrivateParameters) 在 System .Security.Cryptography.RSA.ToXmlString(布尔值 includePrivateParameters)
现在,我相信会发生这种情况,因为当 Azure 将证书添加到我的 WorkerRole 部署时,它不会使用“将此密钥标记为可导出”选项安装证书。
我需要向我的工人角色添加一个证书才能解密加密设置。
任何人都对我如何使 Azure 将证书私钥标记为可导出有任何想法。或者如果这可能是另一个问题。
开始:
try{
var conn = System.Text.UTF8Encoding.UTF8.GetString(Decrypt(Convert.FromBase64String(setting), true, cert));
}catch(Exception ex)
{
Trace.TraceError(ex.ToString());
}
方法:

store.Certificates.Find(X509FindType.FindByThumbprint,
tprint, false);
if (certificateCollection.Count > 0)
{
// We ignore if there is more than one matching cert,
// we just return the first one.
return certificateCollection[0];
}
else
{
throw new ArgumentException("Certificate not found");

finally
