Rachel,

Perhaps if you used Named Notation for the arguments for the procedure, Oracle would understand which of the overloaded procs you're calling.

dbms_obfuscation_toolkit.desencrypt
(

 input_string     => inp_string
,key_string       => 'lksdjfasljf'
,encrypted_string => encrypted_str

)
;

Let us know what works.

Jack

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

Rachel
