Usage

From source file:bft.BFTNode.java

    bos.close();

    byte[] buffer = bos.toByteArray();

    //Add golang idiosyncrasies
    byte[] bytes = new byte[buffer.length + 2];
    bytes[0] = 48; // no idea what this means, but golang's encoding uses it
    bytes[1] = (byte) buffer.length; // length of the rest of the octet string, also used by golang
    for (int i = 0; i < buffer.length; i++) { // concatenate
        bytes[i + 2] = buffer[i];
