help! I am by no means the world's best PL/SQL programmer (heck, I can barely program in it, PL/SQL 101 is on my desk at home)

I am trying to see how hard it would be to add encryption to sensitive data in our database, so I'm playing with DBMS_OBFUSCATION_TOOLKIT.

I created a table:
SQL> desc test_encrypt

Name                            Null?    Type
------------------------------- -------- ----
COL1                                     VARCHAR2(10)
COL2                                     VARCHAR2(10)

and wrote a quick and dirty PL/SQL anonymous block:

begin
declare

    encrypted_str varchar2(10);
    inp_string varchar2(10);

  begin

     inp_string := '123456';
dbms_obfuscation_toolkit.desencrypt(inp_string,'lksdjfasljf',encrypted_str);

     insert into test_encrypt values (inp_string,encrypted_str);
     commit;

  end;
end;
/

when I run this, I get the following error:

     dbms_obfuscation_toolkit.desencrypt
(inp_string,'lksdjfasljf',encrypted_str);

     *
ERROR at line 7:

ORA-06550: line 7, column 6:
PLS-00307: too many declarations of 'DESENCRYPT' match this call
ORA-06550: line 7, column 6:

PL/SQL: Statement ignored

now, I KNOW that they overload the procedure, they say so in the dbmsobtk.sql file in $ORACLE_HOME/rdbms/admin

but what am I doing wrong that it's not recognizing that I'm using varchar not raw and accepting what I input???

Not urgent, but annoying
