Standalone decrypt returning an error

Question

Dear All,
As the part of MAC check mechanism,
We need to decrypt the original data(un encrypted).
But we are getting an error .Can any one suggest on this?
SQL> DECLARE
2 encryption_type PLS_INTEGER := -- total encryption type
3 DBMS_CRYPTO.ENCRYPT_AES128
4 + DBMS_CRYPTO.CHAIN_CBC
5 + DBMS_CRYPTO.PAD_PKCS5;
6 decrypted_raw RAW (2000);
7 BEGIN
8 decrypted_raw := DBMS_CRYPTO.DECRYPT( src => 'FABC12345',
9 typ => encryption_type,
10 key => hextoraw('A1234FEB98491234A1234FEB98491234'));
11 DBMS_OUTPUT.PUT_LINE ( 'Decrypted value: ' || decrypted_raw);
12 END;
13 /

DBMS_OUTPUT.PUT_LINE ( 'Decrypted value: ' || decrypted_raw);
END;
ORA-28817: PL/SQL function returned an error.
ORA-06512: at "SYS.DBMS_CRYPTO_FFI", line 67

Please suggest on the same.
