Microsoft.Data.SqlClient.AlwaysEncrypted.EncryptionAlgorithmFactory

Abstract base class for all TCE cryptographic algorithm factory classes. Factory classes create instances of a cryptographic algorithm with a given key. At runtime when we determine a particular column is marked for TCE, based on the cryptographic algorithm we invoke the corresponding factory class and retrieve an implementation of an cryptographic algorithm.
