Description
The New-SqlColumnEncryptionKey cmdlet creates a column encryption key object in the database. A column encryption key object encapsulates an encrypted value of a symmetric cryptographic key that can be subsequently used to encrypt database columns using the Always Encrypted feature.
This cmdlet supports two modes of operation:
If the encrypted value of a column encryption key is specified, the cmdlet simply creates a new column encryption key object encapsulating the specified encrypted value.
If the encrypted value of a column encryption key is not specified, the cmdlet first generates a plaintext key value, encrypts it with the specified column master key, and then creates a new column encryption key object encapsulating the generated encrypted value. In this mode, the cmdlet communicates with a key store holding the column master key. If the key is stored in Azure, you need to specify a valid authentication token for a key vault or a managed HSM holding the key. Alternatively, you can authenticate to Azure with Add-SqlAzureAuthenticationContext before calling this cmdlet.
Module requirements: version 21+ on PowerShell 5.1; version 22+ on PowerShell 7.x.
Examples
Example 1: Generate and encrypt a column encryption key
New-SqlColumnEncryptionKey -Name 'CEK1' -ColumnMasterKeyName 'CMK1'
This command generates a plaintext value of a column encryption key, encrypts the plaintext value with the specified master key, and then creates a column encryption key object, encapsulating the generated encrypted value in the database.
Example 2: Generate and encrypt a column encryption key using a column master key stored in a key vault in Azure Key Vault.
In this example a token to key vaults in Azure Key Vault is passed to the cmdlet.
# Connect to Azure account.
Import-Module Az.Accounts -MinimumVersion 2.2.0
Connect-AzAccount
# Obtain the access token.
$keyVaultAccessToken = (Get-AzAccessToken -ResourceUrl https://vault.azure.net).Token
# Pass the token to the cmdlet. It will use the token to communicate with the key vault containing the column master key.
New-SqlColumnEncryptionKey -Name 'CEK1' -ColumnMasterKeyName 'CMK1' -KeyVaultAccessToken $keyVaultAccessToken
Example 3: Create a column encryption key object for an existing encrypted value of a column encryption key.
New-SqlColumnEncryptionKey -Name 'CEK1' -ColumnMasterKeyName 'CMK1' -EncryptedValue '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
Parameters
-AccessToken
The access token used to authenticate to SQL Server, as an alternative to user/password or Windows Authentication.
This can be used, for example, to connect to SQL Azure DB and SQL Azure Managed Instance
using a Service Principal or a Managed Identity.
The parameter to use can be either a string representing the token or a PSAccessToken object as returned by running Get-AzAccessToken -ResourceUrl https://database.windows.net.
This parameter is new in v22 of the module.
