Calculating hash value from input of any length

Hi,

I am looking for PLSQL implementation of MD5 algorithm that would work on input of any length, and not just on one varchar2 input string (as dbms_obfuscation_toolkit implementation does).

I need something like this -

create or replace package MD5 as
  procedure initialise;

• procedure initialise resets MD5 calculation procedure datainput( value varchar2 );
• procedure datainput reads piecees of input data function MD5digest return varchar2(16);
• function MD5digest returns MD5 digest calculated for input data end; /

Can anyone give me some help with writing it?

Many Thanks,
