3des encryption

Hi all,

I have created a Oracle database proceudure as follows

CREATE OR REPLACE procedure encrypt_card_1hex(

plain_card_id IN varchar2,

password_t IN varchar2,

enc_card_string out varchar2,

whch IN number)

pseudo_string varchar2(100);

plain_card_string varchar2(24) := plain_card_id;

key_string varchar2(24) := password_t;

encrypted_card_string varchar2(256);

begin

dbms_obfuscation_toolkit.DES3Encrypt(

input_string => plain_card_string,

key_string => key_string,

encrypted_string => encrypted_card_string,

which => whch);

enc_card_string := rawtohex(UTL_RAW.CAST_TO_RAW(encrypted_card_string));

end;

I have created an abap program to encrypt a string using this procedure

PARAMETERs: cr_card(24).

DATA: en_card type c length 48,

pwdc(24),

which TYPE i,

f1(80).

PARAMETERS: crcard type c length 24.

START-OF-SELECTION.

MOVE 'f9ejds73hs727i0z' TO pwdc.

EXEC SQL.

execute procedure

encrypt_card_1hex ( in :crcard, in :pwdc, out :en_card, in 0)

ENDEXEC.

This returns a 32 character string. But if this procedure is called from PL sql, it returns 48 characters. Also if the input cr_card is not a multiple of 8, the program abends with the following error:-

Database error text........: "ORA-28232: invalid input length for obfuscation

toolkit#ORA-06512: at "SYS.DBMS_OBFUSCATION_TOOLKIT_FFI", line 0#ORA-06512: at

"SYS.DBMS_OBFUSCATION_TOOLKIT", line 201#ORA-06512:

Any takers. I have never returned emplty handed from sdn.

thanks

Ravi

I realised that it is possible in 46c
