Change In “Wrap” methods Of oracle Versions

Posted by sriram on May 4, 2011


As we all know ,

We can wrap the source code using wrapper utility.In the same way Oracle has wrapped some objects in Oracle Database By default.

But  there is some change in its wrapping methods.

For Example..
In Oracle 10g

CREATE OR REPLACE FUNCTION “SYSMAN”.”DECRYPT” wrapped

where as in Oracle 11.2.0 the same function wrapped as

MM1SVgqke3o2ohYAkBJWC4PfU//ZEzvyC0TtT+xJsHs8S+BMQbLiMeKs38MrcRD7gl5SzA==

seems its more difficult than 10g.
for Examples see these lines from 10g code.

1FUNCTION:
1DECRYPT:
1CIPHER_TEXT:
1VARCHAR2:
1RETURN:
1RAW_TEXT:
1RAW:
132767:
1DBMS_CRYPTO:
1SRC:
1HEXTORAW:
1TYP:
1ENCRYPT_3DES:
1+:
1CHAIN_CBC:
1PAD_PKCS5:
1KEY:
1GETEMKEY:
1UTL_I18N:
1RAW_TO_CHAR:
1AL32UTF8:

which can give us some clues to re write it as below

create or replace FUNCTION DECRYPT(CIPHER_TEXT IN VARCHAR2)
RETURN VARCHAR2 AS
RAW_TEXT RAW(32767);
BEGIN
IF CIPHER_TEXT IS NULL THEN
RETURN NULL;
END IF;

RAW_TEXT := SYS.DBMS_CRYPTO.DECRYPT(

SRC=>HEXTORAW(CIPHER_TEXT),
TYP=>SYS.DBMS_CRYPTO.ENCRYPT_3DES+SYS.DBMS_CRYPTO.CHAIN_CBC+SYS.DBMS_CRYPTO.PAD_PKCS5,
KEY=>GETEMKEY());

RETURN SYS.UTL_I18N.RAW_TO_CHAR(RAW_TEXT, ‘AL32UTF8‘);
END;

Similarly some other methods.

Hope you Enjoyed it. 😉
