Tao Encryption
==============

[](#tao-encryption)

> This article describes the functioning of tao encryption, focusing of encryption of sensitive data information on a database level.

Installation
------------

[](#installation)

You can add the Tao Encryption as a standard TAO extension to your current TAO instance.

```
 $ composer require oat-sa/extension-tao-encryption
```

Encrypted services supported
----------------------------

[](#encrypted-services-supported)

### 1. Results Encryption

[](#1-results-encryption)

- #### Setup scripts for Tao Server instance

    [](#setup-scripts-for-tao-server-instance)

###### Encrypt

[](#encrypt)

```
 $ sudo -u www-data php index.php 'oat\taoEncryption\scripts\tools\SetupAsymmetricKeys' generate
```

*Note*:

> This command will generate two keys (public and private) and save them on the filesystem.

*Note*:

> On Client Tao instance. You have to copy the public key.

*Note*:

> On Server Tao instance. You need both keys

###### Decrypt

[](#decrypt)

In order to decrypt your results use the following script by passing a delivery id.

```
 $ sudo -u www-data php index.php 'oat\taoEncryption\scripts\tools\DecryptResults' -d
```

Or by passing the -all argument

```
 $ sudo -u www-data php index.php 'oat\taoEncryption\scripts\tools\DecryptResults' -all
```

*Note*:

> This command will decrypt results and store in the delivery result storage setup.

- #### Setup scripts for Tao Client instance

    [](#setup-scripts-for-tao-client-instance)

```
 $ sudo -u www-data php index.php 'oat\taoEncryption\scripts\tools\SetupEncryptedResultStorage'
```

- #### Sync Encrypted Result (Run on Server and client)

    [](#sync-encrypted-result-run-on-server-and-client)

In order to sync encrypted results the script needs to be run on the server tao instance and client as well.

```
 $ sudo -u www-data php index.php 'oat\taoEncryption\scripts\tools\SetupEncryptedSyncResult'
```

### 2. Test State data encryption

[](#2-test-state-data-encryption)

- #### Setup scripts for Tao Client instance

    [](#setup-scripts-for-tao-client-instance-1)

In order to use the encrypted state test service you have to run the following command on tao client instance:

```
 $ sudo -u www-data php index.php 'oat\taoEncryption\scripts\tools\SetupEncryptedStateStorage'
```

```
 $ sudo -u www-data php index.php 'oat\taoEncryption\scripts\tools\SetupEncryptedMonitoringService'
```

This service it's using the symmetric algorithm in order to encrypt information.

### 3. User Encryption

[](#3-user-encryption)

- #### Setup scripts for Tao Client instance

    [](#setup-scripts-for-tao-client-instance-2)

```
 $ sudo -u www-data php index.php 'oat\taoEncryption\scripts\tools\SetupEncryptedUser'
```

- #### Setup scripts for Tao Server instance

    [](#setup-scripts-for-tao-server-instance-1)

```
 $ sudo -u www-data php index.php 'oat\taoEncryption\scripts\tools\SetupUserEventSubscription'
```

- #### Both Instances

    [](#both-instances)

```
 $ sudo -u www-data php index.php 'oat\taoEncryption\scripts\tools\SetupUserSynchronizer'

[](#4-setup-encrypted-file-systems)

- #### Setup scripts for Tao Client instance

    [](#setup-scripts-for-tao-client-instance-3)

```
 $ sudo -u www-data php index.php "oat\taoEncryption\scripts\tools\SetupEncryptedFileSystem" -f private -e taoEncryption/symmetricEncryptionService -k taoEncryption/symmetricFileKeyProvider
```

```
 $ sudo -u www-data php index.php 'oat\taoEncryption\scripts\tools\SetupDeliveryEncrypted'
```

- #### Setup scripts for Tao Server instance

    [](#setup-scripts-for-tao-server-instance-2)

```
 $ sudo -u www-data php index.php 'oat\taoEncryption\scripts\tools\SetupUserApplicationKey'
```

```
 $ sudo -u www-data php index.php 'oat\taoEncryption\scripts\tools\SetupRdfDeliveryEncrypted'
