Generate a new secret key. To generate the key, follow the same process as the one for generating a new private key. You use the Security library in each case. Import encrypted keys more securely. Android 9 (API level 28) and higher allow you to import encrypted keys securely into the Keystore using an ASN.1‑encoded key format. New devices running Android 10 and higher must use file-based encryption. Full-disk encryption is the process of encoding all user data on an Android device using an encrypted key. Once a device is encrypted, all user-created data is automatically encrypted before committing it to disk and all reads automatically decrypt data before returning. Import it into the hardware backed Keystore such that it es decrypted in there with the private key of the pair and stored under a new alias; Use this new key alias to perform symmetric encryption and decryption; 1-4 should be possible, the missing link for me now is point 5. In this list. Jan 20, 2020  Modern encryption is based on digital “keys”. OpenKeychain stores and manages your keys, and those of the people you communicate with, on your Android smartphone. It also helps you find others’ keys online, and exchange keys. But its most frequent use is in using those keys to encrypt and decrypt messages. Deleting and re-creating encryption keys are activities that fall outside of routine encryption key maintenance. You perform these tasks in response to a specific threat to your report server, or as a last resort when you can no longer access a report server database.

Creating and managing keys is an important part of the cryptographic process. Symmetric algorithms require the creation of a key and an initialization vector (IV). The key must be kept secret from anyone who should not decrypt your data. The IV does not have to be secret, but should be changed for each session. Asymmetric algorithms require the creation of a public key and a private key. The public key can be made public to anyone, while the private key must known only by the party who will decrypt the data encrypted with the public key. This section describes how to generate and manage keys for both symmetric and asymmetric algorithms.

Symmetric Keys

The symmetric encryption classes supplied by the .NET Framework require a key and a new initialization vector (IV) to encrypt and decrypt data. Whenever you create a new instance of one of the managed symmetric cryptographic classes using the parameterless constructor, a new key and IV are automatically created. Anyone that you allow to decrypt your data must possess the same key and IV and use the same algorithm. Generally, a new key and IV should be created for every session, and neither the key nor IV should be stored for use in a later session.

To communicate a symmetric key and IV to a remote party, you would usually encrypt the symmetric key by using asymmetric encryption. Sending the key across an insecure network without encrypting it is unsafe, because anyone who intercepts the key and IV can then decrypt your data. For more information about exchanging data by using encryption, see Creating a Cryptographic Scheme.

The following example shows the creation of a new instance of the TripleDESCryptoServiceProvider class that implements the TripleDES algorithm.

When the previous code is executed, a new key and IV are generated and placed in the Key and IV properties, respectively.

Sometimes you might need to generate multiple keys. In this situation, you can create a new instance of a class that implements a symmetric algorithm and then create a new key and IV by calling the GenerateKey and GenerateIV methods. The following code example illustrates how to create new keys and IVs after a new instance of the symmetric cryptographic class has been made.

When the previous code is executed, a key and IV are generated when the new instance of TripleDESCryptoServiceProvider is made. Another key and IV are created when the GenerateKey and GenerateIV methods are called.

Asymmetric Keys

The .NET Framework provides the RSACryptoServiceProvider and DSACryptoServiceProvider classes for asymmetric encryption. These classes create a public/private key pair when you use the parameterless constructor to create a new instance. Asymmetric keys can be either stored for use in multiple sessions or generated for one session only. While the public key can be made generally available, the private key should be closely guarded.

A public/private key pair is generated whenever a new instance of an asymmetric algorithm class is created. After a new instance of the class is created, the key information can be extracted using one of two methods:

  • The ToXmlString method, which returns an XML representation of the key information.

  • The ExportParameters method, which returns an RSAParameters structure that holds the key information.

Both methods accept a Boolean value that indicates whether to return only the public key information or to return both the public-key and the private-key information. An RSACryptoServiceProvider class can be initialized to the value of an RSAParameters structure by using the ImportParameters method.

Asymmetric private keys should never be stored verbatim or in plain text on the local computer. If you need to store a private key, you should use a key container. For more on how to store a private key in a key container, see How to: Store Asymmetric Keys in a Key Container.

The following code example creates a new instance of the RSACryptoServiceProvider class, creating a public/private key pair, and saves the public key information to an RSAParameters structure.

Use Intune to manage a devices built-in disk or drive encryption to protect data on your devices.

Configure disk encryption as part of a device configuration profile for endpoint protection. The following platforms and encryption technologies are supported by Intune:

  • macOS: FileVault
  • Windows 10 and later: BitLocker

Intune also provides a built-in encryption report that presents details about the encryption status of devices, across all your managed devices.

FileVault encryption for macOS

Use Intune to configure FileVault disk encryption on devices that run macOS. Then, use the Intune encryption report to view encryption details for those devices and to manage recovery keys for FileVault encrypted devices.

User-approved device enrollment is required for FileVault to work on the device. The user must manually approve of the management profile from system preferences for enrollment to be considered user-approved.

FileVault is a whole-disk encryption program that is included with macOS. You can use Intune to configure FileVault on devices that run macOS 10.13 or later.

To configure FileVault, create a device configuration profile for endpoint protection for the macOS platform. FileVault settings are one of the available settings categories for macOS endpoint protection.

After you create a policy to encrypt devices with FileVault, the policy is applied to devices in two stages. First, the device is prepared to enable Intune to retrieve and back up the recovery key. This action is referred to as escrow. After the key is escrowed, the disk encryption can start.

For details about the FileVault setting you can manage with Intune, see FileVault in the Intune article for macOS endpoint protection settings.

Silently enable BitLocker on devices

Where To Find Encryption Key

You can configure a BitLocker policy that automatically and silently enables BitLocker on a device. That means that BitLocker enables successfully without presenting any UI to the end user, even when that user isn't a local Administrator on the device.

Device Prerequisites:

A device must meet the following conditions to be eligible for silently enabling BitLocker:

  • The device must run Windows 10 version 1809 or later
  • The device must be Azure AD Joined

BitLocker policy configuration:

The following two settings for BitLocker base settings must be configured in the BitLocker policy:

  • Warning for other disk encryption = Block.
  • Allow standard users to enable encryption during Azure AD Join = Allow

The BitLocker policy must not require use of a startup PIN or startup key. When a TPM startup PIN or startup key is required, BitLocker cannot silently enable and requires interaction from the end user. This requirement is met through the following three BitLocker OS drive settings in the same policy:

  • Compatible TPM startup PIN must not be set to Require startup PIN with TPM
  • Compatible TPM startup key must not set to Require startup key with TPM
  • Compatible TPM startup key and PIN must not set to Require startup key and PIN with TPM

Manage BitLocker

After Intune encrypts a Windows 10 device with BitLocker, you can view and retrieve BitLocker recovery keys when you view the Intune encryption report.

Rotate BitLocker recovery keys

You can use an Intune device action to remotely rotate the BitLocker recovery key of a device that runs Windows 10 version 1909 or later.

Prerequisites

Devices must meet the following prerequisites to support rotation of the BitLocker recovery key:

  • Devices must run Windows 10 version 1909 or later

  • Azure AD-joined and Hybrid-joined devices must have support for key rotation enabled:

    • Client-driven recovery password rotation

    This setting is under Windows Encryption as part of a device configuration policy for Windows 10 Endpoint Protection.

To rotate the BitLocker recovery key

  1. Sign in to the Microsoft Endpoint Manager admin center.

  2. Select Devices > All devices.

  3. In the list of devices that you manage, select a device, select More, and then select the BitLocker key rotation device remote action.
