Creating and deleting temp files

180 New Member
Hi guys,
I have written a function to encrypt and decrypt a file using crypto++. I have made use of crypto++ API's to do that. These API's take one input file(plain text) and outputfile(encrypted file). So two files gets generated...

Now my question is-->
Is there a way by which I can encrypt and decrypt infomation in the same file???

Please suggest taking security into consideration.
