This article provides the steps to provision keys for Always Encrypted using the SqlServer PowerShell module. You can use PowerShell to provision Always Encrypted keys both with and without role separation, providing control over who has access to the actual encryption keys in the key store, and who has access to the database.
'Soft' keys: A key processed in software by Key Vault, but is encrypted at rest using a system key that is in an HSM. Clients may import an existing RSA or EC (Elliptic Curve) key, or request that Key Vault generate one. 'Hard' keys: A key processed in an HSM (Hardware Security Module). These keys are protected in one of the Key Vault HSM. The Azure disk encryption solution lets you encrypt your IaaS virtual machine disks, including boot and data disks. The solution is integrated with Key Vault to help you control and manage the disk encryption keys in your Key Vault subscription, while ensuring that all data in the virtual machine disks are encrypted at rest in your Azure storage.
For an overview of Always Encrypted key management, including some high-level best practice recommendations, see Overview of key management for Always Encrypted.For information about how to start using the SqlServer PowerShell module for Always Encrypted, see Configure Always Encrypted using PowerShell.
Key Provisioning without Role Separation
The key provisioning method described in this section doesn't support role separation between Security Administrators and DBAs. Some of the below steps combine operations on physical keys with operations on key metadata. Therefore, this method of provisioning the keys is recommended for organizations using the DevOps model, or if the database is hosted in the cloud and the primary goal is to restrict cloud administrators (but not on-premises DBAs) from accessing sensitive data. It is not recommended if potential adversaries include DBAs, or if DBAs shouldn't have access to sensitive data.
Before running any steps that involves access to plaintext keys or the key store (identified in the Accesses plaintext keys/key store column in the below table), make sure that the PowerShell environment runs on a secure machine that is different from a computer hosting your database. For more information, see Security Considerations for Key Management.
Windows Certificate Store without Role Separation (Example)Generate Key And Encrypt It With Vault Card
This script is an end-to-end example for generating a column master key that is a certificate in Windows Certificate Store, generating and encrypting a column encryption key, and creating key metadata in a SQL Server database.
Azure Key Vault without Role Separation (Example)
This script is an end-to-end example for provisioning and configuring an Azure Key Vault, generating a column master key in the vault, generating and encrypting a column encryption key, and creating key metadata in an Azure SQL database. https://ccgenerous420.weebly.com/blog/16-digit-random-key-generator.
CNG/KSP without Role Separation (Example)
The below script is an end-to-end example for generating a column master key in a key store that implements Cryptography Next Generation API (CNG), generating and encrypting a column encryption key, and creating key metadata in a SQL Server database.
The example leverages the key store that uses Microsoft Software Key Storage Provider. You may choose to modify the example to use another store, such as your hardware security module. For that, you'll need to make sure the key store provider (KSP) that implements CNG for your device is installed and properly on your machine. You'll need to replace
Microsoft Software Key Storage Provider with your device's KSP name.
Key Provisioning With Role Separation
This section provides the steps to configure encryption where security administrators don't have access to the database, and database administrators don't have access to the key store or plaintext keys.
Security Administrator
Before running any steps that involves access to plaintext keys or the key store (identified in the Accesses plaintext keys/key store column in the below table), make sure that:

DBA
DBAs use the information they receive from the Security Admin (step 6 above) to create and manage the Always Encrypted key metadata in the database. https://ccgenerous420.weebly.com/blog/rocket-league-xbox-one-key-generator.
