Re: Integer to byte*

	There is also the Encode feature that will do more what you originally 
wanted, but I would stick with DEREncode.  You can run a 
BufferedTransformation through HashFilter, but that is just one way. 
The whole sink/source/filter concept throws people at first, but is very 
powerful for quickly generating code once you learn it.  Spend some time 
 looking at the documentation and examples and I think you'll get it.

So calling Integer::DEREncode(bf) will be enough? How to aply hashing on 
bf which is a BufferedTransformation object?

    Well, there is a slight disconnect between Integer and an array of
    octets.  This stems from the multitude of ways they can be represented.
      If you want a byte of the n-bit Integer then you can get one (given
    normal byte boundaries) with GetByte().  You can also get the ASN.1
    encoding on an Integer, which is a stream of octets with a header
    explaining how long it is, and that it is an Integer.
    Normally a definitive format like DEREncoding to ASN.1 then hashing is
    a good way of doing this.  It eliminates ordering and other problems
    that can crop up.
