CLCERT Beacon Observer

This is the unofficial Java SDK to consume the CLCERT Beacon service.

Install

Step 1: Add the JitPack repository to your build file

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

Step 2: Add the dependency

<dependency>
    <groupId>com.github.elbraulio</groupId>
    <artifactId>clcert-beacon-observer</artifactId>
    <version>0.2.0</version>
</dependency>

How to use

Pretty simple to use:

// get an observer.
BeaconObserver beaconObserver = BeaconFactory.observer();

// ask for randomness.
PulseContainer pulseContainer = beaconObserver.lastPulse();

You can ask for specific times as well. Always remember to use UTC.

Instant instant = Instant
                    .now()
                    .atOffset(ZoneOffset.UTC)
                    .toInstant()
                    .truncatedTo(ChronoUnit.MINUTES);
PulseContainer pulseContainer = beaconObserver.pulseBefore(instant);
