How do I create a Key-pair in the Secure Enclave, which I can access from the System Keychain? For a internal project, I need a AD Certificate, where the private key should be stored in the SE. For this I write a Swift Application which generates a key pair in the SE and build a CSR from this.

Secure Enclave is a hardware component of modern Apple mobile devices, such as the iPhone. It is a coprocessor of the device's ARMCPU, in models S2, A7, and later A-series processors. It provides all cryptographic operations for authenticating the user and is designed to be secure even if the iOSkernel is hacked.

PuTTY doesn't natively support the private key format (.pem) generated by Amazon EC2. You must convert your private key into a.ppk file before you can connect to your instance using PuTTY. You can use the PuTTYgen tool for this conversion. This tool, available for both Windows and Unix operating system, can convert keys. PuTTYgen is a key generator tool for creating pairs of public and private SSH keys. It is one of the components of the open-source networking client PuTTY. Although originally written for Microsoft Windows operating system, it is now officially available for. Now convert the PPK keys to SSH keypairs:cache search. To generate the private key: cd puttygen iddsa.ppk -O private-openssh -o iddsa. And to generate the public key: puttygen iddsa.ppk -O public-openssh -o iddsa.pub. Move these keys to /.ssh and make. Generate public key from ppk mac.

Nov 20, 2018  The TPM stores the private key, which requires either your face, fingerprint, or PIN to unlock it. Similarly, a FIDO2 device, like a security key, is a small external device with its own built-in secure enclave that stores the private key and requires the biometric or PIN to unlock it. Oct 31, 2019 Enclave-enabled column encryption key - a column encryption key that is encrypted with an enclave-enabled column master key. When the SQL Server Engine determines operations, specified in a query, need to be performed inside the secure enclave, the SQL Server Engine requests the client driver shares the column encryption keys that are needed for the computations with the secure enclave. Oct 07, 2019  When the device boots, the Secure Enclave generates an ephemeral encryption key and 'entangles' it with a UID (user ID) which cannot be accessed by the rest of the CPU. This key is used to encrypt, and verify the authenticity of, the Secure Enclave's portion of. However, it’s typically easier to store only the private key and then generate the public key from it when needed. That way you don’t need to keep track of another tag or clutter your keychain. For a complete list of available key attributes, see Key Generation Attributes. Be sure that you don’t generate multiple, identically tagged.

Secure Enclave was developed in conjunction with Apple's Touch ID technology, which can identify a user by his or her fingerprint. They were introduced together on September 10, 2013, as part of Apple's announcement of the iPhone 5s, the first device to feature Touch ID.

How it works

  • The Secure Enclave runs a dedicated microkernel and undergoes a secure boot process separate from the rest of the device. It receives its system updates independent of the other CPU components.
  • When the device boots, the Secure Enclave generates an ephemeral encryption key and 'entangles' it with a UID (user ID) which cannot be accessed by the rest of the CPU. This key is used to encrypt, and verify the authenticity of, the Secure Enclave's portion of the device's memory. Any data written to NAND flash storage by the Secure Enclave is encrypted by combining this entangled ephemeral key with an anti-replay counter to prevent data tampering.
  • Authentication data is sent from biometric sensors to the Secure Enclave over a serialbus. The CPU facilitates this operation, but cannot read the data. The data is processed by the Secure Enclave in its encrypted memory space.
  • If the Secure Enclave verifies the biometric data as authentic, it sends a message to the CPU using a 'mailbox' of hardware interrupts. The CPU then permits the user to unlock or make purchases with the device.

Face ID

On September 12, 2017, Apple announced that Face ID, its new biometric authentication technology featured in the iPhone X, replaces Touch ID on newer devices. On the iPhone X, Face ID stores and processes all biometric data in the Secure Enclave of its ARM A11 CPU.

This article provides the steps to provision column master keys and column encryption keys for Always Encrypted using SQL Server Management Studio (SSMS).

For an overview of Always Encrypted key management, including best practice recommendations and important security considerations, see Overview of key management for Always Encrypted.

Provision Column Master Keys with the New Column Master Key Dialog

The New Column Master Key dialog allows you to generate a column master key or pick an existing key in a key store, and create column master key metadata for the created or selected key in the database. Generate public key from private ubuntu.

  1. Using Object Explorer, navigate to the Security>Always Encrypted Keys folder under your database.

  2. Right click on the Column Master Keys folder and select New Column Master Key...

  3. In the New Column Master Key dialog, enter the name of the column master key metadata object.

  4. Select a key store:

    • Certificate Store - Current User - indicates the Current User certificate store location in the Windows Certificate Store, which is your personal store.
    • Certificate Store - Local computer - indicates the Local computer certificate store location in the Windows Certificate Store.
    • Azure Key Vault - you'll need to sign in to Azure (click Sign in). Once you sign in, you'll be able to pick one of your Azure subscriptions and a key vault.
    • Key Store Provider (KSP) - indicates a key store that is accessible via a key store provider (KSP) that implements the Cryptography Next Generation (CNG) API. Typically, this type of a store is a hardware security module (HSM). After you select this option, you'll need to pick a KSP. Microsoft Software Key Store Provider is selected by default. If you want to use a column master key stored in an HSM, select a KSP for your device (it must be installed and configured on the computer before you open the dialog).
    • Cryptographic Service Provider (CSP) - a key store that is accessible via a cryptographic service provider (CSP) that implements the Cryptography API (CAPI). Typically, such a store is a hardware security module (HSM). After you select this option, you'll need to pick a CSP. If you want to use a column master key stored in an HSM, select a CSP for your device (it must be installed and configured on the computer before you open the dialog).

    Note

    Since CAPI is a deprecated API, the Cryptographic Service Provider (CAPI) option is disabled by default. You can enable by creating the CAPI Provider Enabled DWORD value under the [HKEY_CURRENT_USERSoftwareMicrosoftMicrosoft SQL Serversql13ToolsClientAlways Encrypted] key in Windows Registry, and setting it to 1. You should use CNG instead of CAPI, unless your key store does not support CNG.

    For more information about the above key stores, see Create and store column master keys for Always Encrypted.

  5. If you're using SQL Server 2019 (15.x) and your SQL Server instance is configured with a secure enclave, you can select the Allow enclave computations checkbox to make the master key enclave-enabled. See Always Encrypted with secure enclaves for details.

    Note

    The Allow enclave computations checkbox does not appear if your SQL Server instance is not correctly configured with a secure enclave.

  6. Pick an existing key in your key store, or click the Generate Key or Generate Certificate button, to create a key in the key store.

  7. Click OK and the new key will show up in the list.

Once you complete the dialog, SQL Server Management Studio creates metadata for your column master key in the database. The dialog achieves this by generating and issuing a CREATE COLUMN MASTER KEY (Transact-SQL) statement.

If you're configuring an enclave-enabled column master key, SSMS also signs the metadata using the column master key.

Permissions for provisioning a column master key

You need the ALTER ANY COLUMN MASTER KEY database permission in the database for the dialog to create a column master key. To use the dialog to create a new column master key or use an existing key in a key store create, you might require permissions on the key store or/and the key:

  • Certificate Store - Local computer - you must have Read access to the certificate that is used as a column master key, or be the administrator on the computer.
  • Azure Key Vault - you need the get and list permissions to select and use a key, the create permission to create a new key. To configure an enclave-enabled column master key, you also need the sign permission to generate a signature of the key metadata.
  • Key Store Provider (CNG) - you might be prompted for the required permission and credentials when using a key store or a key, depending on the store and the KSP configuration.
  • Cryptographic Service Provider (CAPI) - you might be prompted for the required permission and credentials when using a key store or a key, depending on the store and the CSP configuration.

For more information, see Create and store column master keys for Always Encrypted.

Provision Column Encryption Keys with the New Column Encryption Key Dialog

Generate Key In Secure Enclave Key

The New Column Encryption Key dialog allows you to generate a column encryption key, encrypt it with a column master key, and create the column encryption key metadata in the database.

Generate Key In Secure Enclave 2017

  1. Using Object Explorer, navigate to the Security/Always Encrypted Keys folder under your database.
  2. Right click on the Column Encryption Keys folder and select New Column Encryption Key...
  3. In the New Column Encryption Key dialog, enter the name of the column encryption key metadata object.
  4. Select a metadata object that represents your column master key in the database.
  5. Click OK.
Secure

Once you complete the dialog, SQL Server Management Studio generates a new column encryption key and then it retrieves the metadata for the column master key you selected from the database. SSMS then uses the column master key metadata to contact the key store containing your column master key and encrypt the column encryption key. Finally, SSMS creates the metadata data for the new column encryption in the database by generating and issuing a CREATE COLUMN ENCRYPTION KEY (Transact-SQL) statement.

Windows Secure Enclave

Permissions for provisioning a column encryption key

You need the ALTER ANY COLUMN ENCRYPTION KEY and VIEW ANY COLUMN MASTER KEY DEFINITION database permissions in the database for the dialog to create the column encryption key metadata and to access column master key metadata.To access a key store and use the column master key, you might require permissions on the key store or/and the key:

  • Certificate Store - Local computer - you must have Read access to the certificate that is used as a column master key, or be the administrator on the computer.
  • Azure Key Vault - you need the get, unwrapKey, wrapKey, sign, and verify permissions on the vault containing the column master key.
  • Key Store Provider (CNG) - you might be prompted for the required permission and credentials when using a key store or a key, depending on the store and the KSP configuration.
  • Cryptographic Service Provider (CAPI) - you might be prompted for the required permission and credentials when using a key store or a key, depending on the store and the CSP configuration.

For more information, see Create and store column master keys (Always Encrypted).

Provision Always Encrypted Keys using the Always Encrypted Wizard

The Always Encrypted Wizard is a tool for encrypting, decrypting, and re-encrypting selected database columns. While it can use already configured keys, it also allows you to generate a new column master key and a new column encryption.
