Description
The New-SqlColumnMasterKey cmdlet creates a column master key object in the database. A column master key object captures the ___location of a physical cryptographic key that is intended to be used as a column master key for the Always Encrypted feature.
Examples
Example 1: Create a column master key object that references a certificate
$CmkSettings = New-SqlCertificateStoreColumnMasterKeySettings -CertificateStoreLocation 'CurrentUser' -CertificateThumbprint 'f2260f28d909d21c642a3d8e0b45a830e79a1420'
New-SqlColumnMasterKey -Name 'CMK1' -ColumnMasterKeySettings $CmkSettings
The first command uses the New-SqlCertificateStoreColumnMasterKeySettings cmdlet to create a column
master settings referencing a certificate in Windows Certificate Store and stores the result in the
variable named $CmkSettings.
Example 2: Create a column master key object that references a key in Azure Key Vault
$CmkSettings = New-SqlAzureKeyVaultColumnMasterKeySettings -KeyUrl 'https://myvault.vault.contoso.net/keys/CMK/4c05f1a41b12488f9cba2ea964b6a700'
New-SqlColumnMasterKey 'CMK1' -ColumnMasterKeySettings $CmkSettings
The first command uses the New-SqlCertificateStoreColumnMasterKeySettings cmdlet to create
column master key object referencing a key in Azure Key Vault and stores the result in the
variable named $CmkSettings.
Example 3: Create a column master key object that references a key supporting CNG
$CmkSettings = New-SqlCngColumnMasterKeySettings -CngProviderName 'Microsoft Software Key Storage Provider' -KeyName 'AlwaysEncryptedKey'
New-SqlColumnMasterKey 'CMK1' -ColumnMasterKeySettings $CmkSettings
The first command uses the New-SqlCertificateStoreColumnMasterKeySettings cmdlet to create column
master key object referencing a key in a key store supporting the Cryptography Next Generation (CNG)
API and stores the result in the variable named $CmkSettings.
Example 4: Create a column master key object that references a key supporting CSP
$CmkSettings = New-SqlCspColumnMasterKeySettings 'MyCspProvider' 'AlwaysEncryptedKey'
New-SqlColumnMasterKey 'CMK1' -ColumnMasterKeySettings $CmkSettings
The first command uses the New-SqlCertificateStoreColumnMasterKeySettings cmdlet to create column master key object referencing a key in a key store key store with a Cryptography Service Provider (CSP) supporting Cryptography API (CAPI).
Example 5: Create a column master key object that references a certificate, it is auto-signed and supports enclave computations
$CmkSettings = New-SqlCertificateStoreColumnMasterKeySettings -CertificateStoreLocation 'CurrentUser' -CertificateThumbprint 'f2260f28d909d21c642a3d8e0b45a830e79a1420' -AllowEnclaveComputations
New-SqlColumnMasterKey -Name 'CMK1' -ColumnMasterKeySettings $CmkSettings
The first command uses the New-SqlCertificateStoreColumnMasterKeySettings cmdlet to create column master settings referencing a certificate that supports enclave computations and is stored in Windows Certificate Store.
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.
Parameter properties

| Supports wildcards: | False |
| DontShow: | False |
Parameter sets
(All)
| Position: | Named |
| Mandatory: | False |
| Value from pipeline: | False |
| Value from pipeline by property name: | False |
| Value from remaining arguments: | False |
-ColumnMasterKeySettings
Specifies the SqlColumnMasterKeySettings object that specifies the ___location of the actual column master key.
The SqlColumnMasterKeySettings object has two properties: KeyStoreProviderName and KeyPath.
KeyStoreProviderName specifies the name of a column master key store provider, which an Always Encrypted-enabled client driver must use to access the key store containing the column master key.
KeyPath specifies the ___location of the column master key within the key store. The KeyPath format is specific to the key store.
Parameter properties
| Type: | SqlColumnMasterKeySettings |
| Default value: | None |
| Supports wildcards: | False |
| DontShow: | False |
Parameter sets
(All)
| Position: | Named |
| Mandatory: | True |
| Value from pipeline: | False |
| Value from pipeline by property name: | False |
| Value from remaining arguments: | False |
-Encrypt
The encryption type to use when connecting to SQL Server.
This value maps to the Encrypt property SqlConnectionEncryptOption on the SqlConnection object of the Microsoft.Data.SqlClient driver.
In v22 of the module, the default is Optional (for compatibility with v21). In v23+ of the module, the default value will be 'Mandatory', which may create a breaking change for existing scripts.
This parameter is new in v22 of the module.

| Value from remaining arguments: | False |
-HostNameInCertificate
The host name to be used in validating the SQL Server TLS/SSL certificate. You must pass this parameter if your SQL Server instance is enabled for Force Encryption and you want to connect to an instance using hostname/shortname. If this parameter is omitted then passing the Fully Qualified Domain Name (FQDN) to -ServerInstance is necessary to connect to a SQL Server instance enabled for Force Encryption.
This parameter is new in v22 of the module.
