SqlColumnEncryptionEnclaveProvider
Remarks
An enclave is a protected region of memory inside SQL Server, used for computations on encrypted columns. An enclave provider encapsulates the client-side implementation details of the enclave attestation protocol as well as the logic for creating and caching enclave sessions.
Constructors
| SqlColumnEncryptionEnclaveProvider() |
Initializes a new instance of the SqlColumnEncryptionEnclaveProvider class. |
Methods
| CreateEnclaveSession(Byte[], ECDiffieHellmanCng, String, String, SqlEnclaveSession, Int64) |
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. |
| Equals(Object) |
Determines whether the specified object is equal to the current object. (Inherited from Object) |
| GetAttestationParameters() |
Gets the information that SqlClient subsequently uses to initiate the process of attesting the enclave and to establish a secure session with the enclave. |
| GetEnclaveSession(String, String, SqlEnclaveSession, Int64) |
When overridden in a derived class, looks up an existing enclave session information in the enclave session cache. If the enclave provider doesn't implement enclave session caching, this method is expected to return |
| GetHashCode() |
Serves as the default hash function. (Inherited from Object) |
| GetType() |
Gets the Type of the current instance. (Inherited from Object) |
| InvalidateEnclaveSession(String, String, SqlEnclaveSession) |
When overridden in a derived class, looks up and evicts an enclave session from the enclave session cache, if the provider implements session caching. |
| MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
| ToString() |
Returns a string that represents the current object. (Inherited from Object) |
