Add data to binary file -
I would like to add some data to a binary file and then later strip the data from a binary file at a later date.
What I am thinking is to take a file(Zip, Word, excel, or txt) and take the name of the file and add it to the file or append to the file. Then I plan on encrypting the file and renaming the resulting encrptyed file to something.encrpt. Thus in affect hiding the name of the encrptyed file as well as it's data.
Anyone have a starting point on doing something like this?
thanks,
Dean
