Scope

This library offers an easy way to encrypt and decrypt XML documents and String objects. It is based on a symmetric key based on the AES standard for cryptography.

Sample Usage

These samples are taken from the exploitation the resource library does of the encryption library for protecting the AccessData content of the RuntimeResource class.

Encryption

import org.gcube.common.utils.encryption.StringEncrypter;
 
//...
resource.setAccessData(new StringEncrypter("my sensible data").encrypt());

After serialization, the resource will appears as follows: 

<?xml version='1.0' encoding='UTF-8' standalone='yes' ?>
<Resource version="0.4.x">
	<ID>ac41d0d0-4791-11e1-b442-a3a8a4cd06fd</ID>
	<Type>RuntimeResource</Type>
	<Profile>

		<Name>resource name</Name>
		<Description>a description</Description>
		<Platform>
			<Name>Test platform</Name>
			<Version>1</Version>
			<MinorVersion>1</MinorVersion>
		</Platform>
		<RunTime>
			<HostedOn>macos-manuele</HostedOn>
			<GHN UniqueID="123456789"/>
			<Status>READY</Status>
		</RunTime>
		<AccessPoint>
			<Interface>
				<Endpoint EntryName="ap">http://myaccesspoint.eu</Endpoint>
			</Interface>
			<AccessData>dtvKM4JImPLQvboHwBvKEur1tbvdnKXYB82AICLq5/c=</AccessData>
		</AccessPoint>
	</Profile>
</Resource>

Decryption

import org.gcube.common.utils.encryption.StringEncrypter;
 
//...
AccessPoint ap = new AccessPoint();
ap.setAccessData(new StringEncrypter(this.load("AccessData")).decrypt());
System.out.println("Access data's content: " + ap.getAccessData());

This will print the following line: 

Access data's content: my sensible data
