Setup PureKit

This guide is the first step to adding password-hardened encryption to your solution. Here you can learn how to set up PureKit at your backend to protect your users's passwords and data.

For more details about password-hardened encryption (PHE), take a look at our overview here.

Before you begin

Install PureKit

Use your package manager to install PureKit at your backend.

The PureKit Kotlin/Java SDK is provided as a package named purekit with group id named com.virgilsecurity. You can either use Gradle or Maven to add it to your project dependencies.

Maven Add jcenter repository:

<repositories>
    <repository>
        <id>jcenter</id>
        <name>jCenter</name>
        <url>http://jcenter.bintray.com</url>
    </repository>
</repositories>

and add purekit dependency:

<dependencies>
    <dependency>
        <groupId>com.virgilsecurity</groupId>
        <artifactId>purekit</artifactId>
        <version><latest-version></version>
    </dependency>
</dependencies>

Gradle

Add jcenter repository:

repositories {
    jcenter()
}

and add purekit dependency:

implementation 'com.virgilsecurity:purekit:<latest-version>'

The <latest-version> of the SDK can be found in the Maven Central Repository: https://mvnrepository.com/artifact/com.virgilsecurity/purekit

Initialize PureKit

Use the previously generated credentials to configure PureKit:

PureContext context = PureContext.createContext( "AT.znqRZcOdzybj62Rzer897pX2DZ9KZoYF", "NM.Qs0YFBS7Mr3Aaa9qn4OCVcNC1wvPCXfUpZNWFCPUOUI=", "BU.MCowBQYDK2VwAyEAKWSBAZbbekJ5Ns36jRcjEiut3rH4rpaCCVnRxcB+d/E=", "SK.1.ieSin9pO6Bx96+RJw/85fARl4fWdD9DfU/JQF+mbdqE=.hMnMH+oIg8eKZNxGq27LYQbzK4gDlvWvMLJh3jBCkRk=.ug2KqJdUl50kYx+/RKcACLCR4zAujSlK6vQMvDKst+w=", "PK.1.BO/YeE7oxlUad1TSpKb3DtudynpwB9miM/+1CsMkmf50qP/QUaYt7pXIxrsyLh38u08p6FFkCWedy/VhA//2MJY=.BPkoDhRO/01QmA8JIVcqxMQKrXfA4agTjBFEm42Lh5NIimcEFWUNWXZwq1Q962rxfkJd7kNZDpm0mlPLeHU+iyI=", null); Pure pure = new Pure(context);

If you want to use your own custom storage instead of Virgil Cloud for storing encryption keys and user records - for example, if you need a better performance - you'll need to go through the Set Up Custom Storage guide.

Next step

Now that you have PureKit installed and configured, you can move on to encrypting users' passwords as a part of user authentication:
