gdata-vaas

An SDK to easily utilize G DATA VaaS.

Verdict-as-a-Service (VaaS) is a service that provides a platform for scanning files for malware and other threats. It allows easy integration in your application. With a few lines of code, you can start scanning files for malware.

What does the SDK do?

It gives you as a developer a functions to talk to G DATA VaaS. It wraps away the complexity of the API into 3 basic functions.

forSha256

If you calculate the sha256 for a file, you can request that sha256 against G DATA VaaS. It's the fastest way to get a verdict from our service.

forUrl

If you want to request if a file behind a URL is safe, you can specify the URL as well. Depending on the file size, the duration for the analysis can vary.

forFile

You can also ask for a file itself. You will still get the benefit of a fast verdict via Sha256 because the SDK will do that for you first. But additionally, if we don't know the file, the file will get uploaded and (automatically) analyzed by us.

How to use

Installation

Add this in your build.gradle:

implementation 'de.gdata:vaas'

Import

import de.gdata.vaas.ClientCredentialsGrantAuthenticator;
import de.gdata.vaas.Vaas;
import de.gdata.vaas.VaasConfig;

Request a verdict

Authentication & Initializing:

var authenticator = new ClientCredentialsGrantAuthenticator(
    CLIENT_ID,
    CLIENT_SECRET,
    TOKEN_URL
    );
var config = new VaasConfig(
        new URI(TOKEN_URL),
        new URI(VAAS_URL));
var vaas = new Vaas(config, authenticator);
vaas.connect();

Verdict Request for SHA256:

var sha256 = new Sha256("000005c43196142f01d615a67b7da8a53cb0172f8e9317a2ec9a0a39a1da6fe8");
var verdict = vaas.forSha256(sha256);

vaas.disconnect();

System.out.printf("File %s was detected as %s", verdict.getSha256(), verdict.getVerdict());

Verdict Request for a file:

var file = Path.of(SCAN_PATH);
var verdict = vaas.forFile(file);

vaas.disconnect();

System.out.printf("File %s was detected as %s", verdict.getSha256(), verdict.getVerdict());

Verdict Request for a URL:

var url = new URL("https://www.gdatasoftware.com/oem/verdict-as-a-service");
var verdict = vaas.forUrl(url);

vaas.disconnect();

System.out.printf("File %s was detected as %s", verdict.getSha256(), verdict.getVerdict());
