Definition

Namespace:

Microsoft.Data.SqlClient

Assembly:

Microsoft.Data.SqlClient.dll

Package:

Microsoft.Data.SqlClient v5.2.0

Encrypts the given plain text column encryption key using an asymmetric key specified by the key path and the specified algorithm. The key path will be in the format of [ProviderName]/KeyIdentifier and should be an asymmetric key stored in the specified CNG key store provider. The valid algorithm used to encrypt/decrypt the CEK is 'RSA_OAEP'.
