java get sha output in raw 20 characters binary format

Question

I have tried a bunch of different ways to solve this and referred to endless SO posts and most of them lead me to the hex encoded value.

Based on one of the answers on formatting the output I thought the following snippet would do the trick

Formatter formatter = new Formatter();
    for (byte b : hash) {
        formatter.format("%02o", b);
    }
    return formatter.toString();

I am trying to emulate the php sha1 function with the second parameter set to true.

Any help is much appreciated.
