[namedgraphs] Digest encoding

[Blom, J.J.C. (Jaap) <jb...@cr...>]

Hi,

I was wondering why the digest for a data graph is first hexadecimal encoded and then base 64 encoded (instead of only base 64 encoded like the signature for a warrant graph). I conclude this on basis of the code from NG4J 0.9.3. In de.fuberlin.wiwiss.ng4j.swp.util.SWPSignatureUtilities in the function protected static String calculateDigest( String dataInCanonicalForm, Node digestMethod ) on line 225 the following lines of code are present:
        res = Hex.encode( resBuf );
        return new String(Base64.encodeBase64( res )) ;



I suspect that this is a bug, am I correct?

Greetings,
  Jaap Blom
