Trouble calling dbms_obfuscation_toolkit.desdecrypt

I'm trying to:

create or replace
  function decrypt (p_str in varchar2, p_key in varchar2) return varchar2   is
    str varchar2(16);
  begin
    dbms_obfuscation_toolkit.desdecrypt(p_str,p_key,str);     return str;
  end;
/

sho err

LINE/COL ERROR

-------- -----------------------------------------------------------------
5/5      PLS-00307:  too many declarations of 'DESDECRYPT' match this call
5/5      PL/SQL: Statement ignored

What am I doing wrong?

(Yes, I know there are two versions of desdecrypt(), one raw and one varchar2 version. But that can't be the problem here?).
