BigInteger number = new BigInteger(bb.array()).abs();
return encode58(number);
byte[]uuidToByteArray(UUID uuid)
uuid To Byte Array 
ByteBuffer bb = ByteBuffer.wrap(new byte[16]);
bb.putLong(uuid.getMostSignificantBits());
bb.putLong(uuid.getLeastSignificantBits());
return bb.array();
byte[]uuidToBytes(UUID id)
uuid To Bytes 
byte[] b = new byte[16];
return ByteBuffer.wrap(b).order(ByteOrder.BIG_ENDIAN).putLong(id.getMostSignificantBits())
        .putLong(id.getLeastSignificantBits()).array();
byte[]uuidToBytes(UUID uuid)
uuid To Bytes 
byte[] bytes = new byte[16];
ByteBuffer buffer = ByteBuffer.wrap(bytes);
buffer.order(ByteOrder.LITTLE_ENDIAN);
buffer.putInt((int) (uuid.getMostSignificantBits() >> 32));
buffer.putShort((short) (uuid.getMostSignificantBits() >> 16));
buffer.putShort((short) uuid.getMostSignificantBits());
buffer.order(ByteOrder.BIG_ENDIAN);
buffer.putLong(uuid.getLeastSignificantBits());

byte[]uuidToBytes(UUID uuid)
Converts an UUID to byte array. 
byte[] bytes = new byte[(Long.SIZE >> 3) * 2];
uuidToBytes(uuid, bytes, 0);
return bytes;
byte[]uuidToBytes(UUID uuid)
Converts a UUID object to a byte array for storing in MySQL. 
ByteBuffer bb = ByteBuffer.wrap(new byte[16]);
bb.putLong(uuid.getMostSignificantBits());
bb.putLong(uuid.getLeastSignificantBits());
return bb.array();
byte[]uuidToBytesNullOk(UUID uuid)
uuid To Bytes Null Ok 
if (uuid != null) {
    return bytes(uuid);
