hi,

I was wondering is there any way to decrypt pdf files which has been already encrypted by another application and know are save in our oracle DB as BLOB fields?

I have spent some time with Decrypt procedure with no success because of getting "ORA-01405: fetched column value is NULL" error message :

PROCEDURE Decrypt (dst IN OUT NOCOPY BLOB,
src IN BLOB,
typ IN PLS_INTEGER,
key IN RAW,
iv IN RAW DEFAULT NULL);

I realy don't know is this error occure becuase type of my file which is PDF or is it because other resoans?

Thanks in advance,

Just becuase a PDF is in a blob field, doesn't mean it's "encrypted". Maybe yours is encrypted though? You need to get the decryption details from whoever did the encryption. That proc doesn't look like it came from Oracle corp.
