create or replace function crypt( p_str in varchar2 )
return varchar2
as
l_data varchar2(255);
begin
l_data := rpad( p_str, (trunc(length(p_str)/8)+1)*8, chr(0) );
dbms_obfuscation_toolkit.DESEncrypt
( input_string => l_data,
key_string => 'MagicKey',
encrypted_string=> l_data );
return UTL_RAW.CAST_TO_RAW( l_data );
end;

Function created

SQL> select crypt( '012345678 ') from dual;
select crypt( '012345678 ') from dual
