Encryption & Backup : I'm need some help on a project, the plan is to make a c program that can take an input file name and then do these three tasks
1-copy it's contents and store it's duplicate in another user specified location
2-change the backup file's format i.e from ".txt" to something like ".img"
3-encrypt the contents of file(any cypher method)
------*note: the input file name has to be scanned during execution
I and my team have already made about 75% of it but it's in separate parts like each of the following three tasks is an individual program..and we are having trouble combining them.
Another error is that we are using "rename" function from files concept to copy files and change their format and we don't have any idea of how to use scanf to read the file name and give it as input to the rename function..
So if you could give me any suggestions..I'd really be grateful.
