Document

Returns a big-endian representation of value in an 8-element byte array; equivalent to ByteBuffer.allocate(8).putLong(value).array() .

Usage

From source file:io.warp10.crypto.CryptoUtils.java

public static byte[] addMAC(byte[] key, byte[] data) {
    long hash = SipHashInline.hash24_palindromic(key, data);

    byte[] authenticated = Arrays.copyOf(data, data.length + 8);
    System.arraycopy(Longs.toByteArray(hash), 0, authenticated, data.length, 8);

    return authenticated;
}
