SqlColumnEncryptionEnclaveProvider.CreateEnclaveSession Method

Definition

Namespace:

System.Data.SqlClient

Assembly:

System.Data.dll

When overridden in a derived class, performs enclave attestation, generates a symmetric key for the session, creates a an enclave session and stores the session information in the cache.

public:
 abstract void CreateEnclaveSession(cli::array <System::Byte> ^ enclaveAttestationInfo, System::Security::Cryptography::ECDiffieHellmanCng ^ clientDiffieHellmanKey, System::String ^ attestationUrl, System::String ^ servername, [Runtime::InteropServices::Out] System::Data::SqlClient::SqlEnclaveSession ^ % sqlEnclaveSession, [Runtime::InteropServices::Out] long % counter);

public abstract void CreateEnclaveSession (byte[] enclaveAttestationInfo, System.Security.Cryptography.ECDiffieHellmanCng clientDiffieHellmanKey, string attestationUrl, string servername, out System.Data.SqlClient.SqlEnclaveSession sqlEnclaveSession, out long counter);

Public MustOverride Sub CreateEnclaveSession (enclaveAttestationInfo As Byte(), clientDiffieHellmanKey As ECDiffieHellmanCng, attestationUrl As String, servername As String, ByRef sqlEnclaveSession As SqlEnclaveSession, ByRef counter As Long)

Parameters

enclaveAttestationInfo

Byte[]

The information the provider uses to attest the enclave and generate a symmetric key for the session. The format of this information is specific to the enclave attestation protocol.

clientDiffieHellmanKey

ECDiffieHellmanCng

A Diffie-Hellman algorithm object that encapsulates a client-side key pair.

attestationUrl

String

The endpoint of an attestation service for attesting the enclave.

servername

String

The name of the SQL Server instance containing the enclave.

sqlEnclaveSession

SqlEnclaveSession

The requested enclave session or null if the provider doesn't implement session caching.

counter

Int64

A counter that the enclave provider is expected to increment each time SqlClient retrieves the session from the cache. The purpose of this field is to prevent replay attacks.
